2.0 TERMINOLOGIE 2.1 Dispozitive electrice si de

automatizare

Dispozitive de operare electrice si de automatizare Sunt dispozitive de operare in conditii de siguranta, destinate controlului respectiv comandarii instalatiilor in domeniul lor de lucru (parametri normali). Daca exista un sistem de dirijare procese (PLC), dispozitivele de operare electrice si de automatizare se vor concretiza in acest sistem.

2.0 TERMS 2.1 Measurement and control equipment

Measurement and control operating equipment

Equipment that ensures proper operation when monitoring or controlling systems within their acceptable range. Where a process control system exists, measurement and control operating equipment is to be realized as an integral part of this system.

Norma Petrom OMV K 1002 / Petrom OMV Standard K 1002 Pagina/Page 3

Dispozitivele de monitorizare electrice si de automatizare Dispozitivele de monitorizare electrice si de automatizare (Clasa C) semnalizeaza deficientele admise de functionare a instalatiei, pentru a determina acordarea unei atentii sporite sau realizarea unei interventii manuale din partea personalului operator sau se declanseaza automat pentru readucerea parametrilor de proces in domeniul de acceptanta.

Measurement and control monitoring equipment

Measurement and control monitoring equipment (class C) provides feedback on permissible error states in the plant in order to increase awareness or facilitate manual intervention by operating personnel. The equipment also intervenes automatically where process variables stray outside the acceptable range.

Dispozitivele de monitorizare electrice si de automatizare nu trebuie sa indeplineasca conditii speciale. Ele vor fi realizate ca si dispozitivele de operare electrice si de automatizare.

No special requirements apply for measurement and control monitoring equipment. These must be implemented in the same way as measurement and control operating equipment.

Dispozitivele de protectie din domeniul electric si de automatizare La dispozitivele de protectie din domeniul electric si de automatizare trebuie sa se faca distinctia intre dispozitivele din Clasa A si cele din Clasa B.

Measurement and control protective equipment

There is a difference between class A and class B measurement and control protective equipment.

Dispozitivele din Clasa A servesc la evitarea accidentarii personalului, a pagubelor mari produse mediului inconjurator, ca si la evitarea cazurilor de perturbatii si defecte

Class A measurement and control protective equipment serves to prevent injury to persons or major environmental damage and accidents, as well as to avoid disturbances and faults.

Printre acestea se numara de ex. dispozitivele primare de siguranta cum ar fi cele de protectie la suprapresiune daca sunt utilizate in locul supapelor de siguranta. Vezi si dispozitive electrice si de automatizare cu functie de siguranta.

This includes primary safety equipment such as overpressure protection (for example), if installed instead of safety valves. Also see safety-relevant measurement and control equipment.

Trebuie luate masuri adecvate pentru ca aceste dispozitive sa nu poata fi dezactivate. Dispozitivele de protectie AMC din Clasa B sunt destinate evitarii pagubelor materiale de mai mare amploare.

Measures must be taken to ensure that this equipment cannot be inoperative. Class B measurement and control protective equipment serves to prevent major material damage.

2.2 Notiuni de specialitate VPS Scheme semnalizare si blocare: Structurata din componente (inclusiv cartele electronice) in tehnologie cu cablare fixa.

2.2 Technical terms HCS Hardwired control system: Assembly of components (also electronic cards) using hardwired technology.

SSPS Comanda programabila cu functie de siguranta

SPLC Safety programmable logic controller

PRINCIPIUL CURENTULUI DE REPAUS In cazul caderii sursei de tensiune respectiv al ruperii cablului, se declanseaza alarma.

CLOSED-CIRCUIT CURRENT PRINCIPLE An alarm is output in the event of a power failure or cable break.


In varianta de executie cu un canal, comanda aduce automat partea de instalatie respectiva in pozitia sa de siguranta.

The single channel version of the controller automatically brings the affected plant component into the fail safe position.

PRINCIPIUL FAIL-SAFE (VDI/VDE 3542 Fisa 1) Model de comanda cu siguranta la defect: Sistemul preia functia de verificare curenta si se autoverifica. In cazul constatarii unei perturbatii sau deranjament, ca si in cazul principiului curentului de repaus, comanda readuce componenta respectiva in pozitia de siguranta. Daca se utilizeaza sisteme Fail-Safe in dispozitivele de protectie AMC, va fi necesara prezentarea unui certificat de avizare a functionarii Fail Safe a dispozitivului respectiv (de ex. Certificat TV).

FAILSAFE PRINCIPLE (VDI/VDE 3542 Sheet 1) Failsafe design of controller: The system performs the necessary running function check and a self test. In the event of a fault the controller brings the affected plant component into the failsafe position (as is the case with the closed-circuit configuration). Where failsafe systems are implemented in measurement and control protective equipment, certification regarding the Fail Safe function of the components used is required (for example: certification by technical inspection authority- TUV).

DIVERSITATE Inseamna, printre altele, constructie de tipuri diverse, cu mai multe canale (de ex. un canal in curent de repaus, alt canal in curent de lucru)

diverse principii de masurare la emitatoarele de valoare masurata

diverse tipuri de software diverse organe de reglare

DIVERSITY Means (amongst other things) multi-channel heterogeneous design (one channel implemented using closed-circuit current, the other channel using operating current)

various measuring principles of feedback devices

range of software range of control elements

EXECUTIE CU DOUA CANALE Logica de comanda este realizata de doua ori (doua canale). O functie de control da alarma in cazul in care identifica un status diferit al celor doua sisteme de logica de comanda. Rezultatul (declansarea decuplarii) actioneaza ca logica 2 din 2 asupra cartelelor de iesire. Declansarea deconectarii se produce si in cazul identificarii deranjamentelor in ambele canale. Realizarea cu doua canale a logicii de comanda se va face intotdeauna in tehnica Fail-Safe. Scopul acestei variante de executie cu doua canale este marirea gradului de disponibilitate a logicii de comanda.

DUAL-CHANNEL DESIGN The control logic is duplicated (two channels). An antivalence check is performed and an alarm is generated if the control logic states differ. The combined effect (activation of shutdown) of the two control logic systems acts as 2 out of 2 logic on the output cards. Shutdown is also triggered in the event of a fault in both channels. A dual-channel control logic design must always be implemented using Fail Safe technology. The purpose of the dual-channel design is to increase availability of the control logic.

COMUTARE 2 din 3 Declansarea deconectarii se produce in momentul atingerii a doua valori de comutare. Fiecare circuit este semnalizat separat. Cu sistemul de comutare 2 din 3 se sporeste gradul de siguranta si disponibilitate. Ca o consecina circuitele, inclusiv sursa de impuls, trebuie sa fie realizate separat.

2 out of 3 CIRCUIT Shutdown is triggered when 2 switching values are reached. A signal is output for each circuit separately. Where 2 out of 3 circuits are used this increases safety and availability. As a consequence however, the circuits (including impulse sampling) must be implemented separately.

COMUTARE 1 din 2 Declansarea deconectarii se produce direct la momentul atingerii unuia din cele doua puncte

1 of 2 CIRCUIT Shutdown is triggered as soon as one of the two switching points is reached.


de comutare.

Se obtine o crestere a gradului de siguranta insa o diminuare a disponibilitatii. Ca si la comutarea 2 din 3, circuitele, inclusiv sursa de impuls, trebuie sa fie realizate separat.

This increases safety but reduces availability. As is the case with the 2 out of 3 circuit these circuits (including impulse sampling) must be implemented separately.

3.0 PRINCIPII DE UTILIZARE

Inainte de alegerea tipului de comanda, fiecare functie va fi clasificata dupa gradul sau de risc si va fi asociata unuia din dispozitivele de protectie din domeniul electric si automatizarii de la punctul 2.1 (vezi si punctul 7.0).

Utilizarea dispozitivelor de protectie electrice si de automatizare Clasa A si B va fi limitata la un volum minimal. Dispozitivele de protectie AMC Clasa A si B vor fi realizate identic din punct de vedere tehnic.

Pentru dispozitivele de protectie electrice si automatizare se va folosi de preferinta VPS. (scheme semnalizare si blocare).

3.0 BASIC PRINCIPLES OF USE

Before the controller is selected, the risk associated with each individual task must be classified and assigned to an item of measurement and control equipment (in accordance with item 2.1) (see item 7.0).

Whenever possible, the use of class A and class B measurement and control protective equipment must be kept to a minimum. In technical terms, the implementation of class A and B measurement and control protective equipment must be identical.

Whenever possible, hardwired control systems should be used for measurement and control protective equipment.

Fundamentare: Constructia dispozitivelor de protectie electrice si de automatizare trebuie sa fie simpla si logica (deductibila). Un dispozitiv de protectie AMC nu va fi niciodata, respectiv va fi foarte rar, modificat in timpul functionarii.Intr-o instalatie tehnologica numai putine dispozitive electrice si de automatizare sunt realizate si ca dispozitive de protectie. Utilizarea altor tehnologii va fi convenita cu responsabilul de proiect pentru electric automatizari Petrom OMV.Pentru dispozitivele de protectie electrice si de automatizare, principiul Fail-Safe va fi aplicat corespunzator celei mai avansate tehnologii disponibile si recunoscute.

Dispozitivele care nu sunt realizabile pe principiul Fail-Safe vor fi realizate cel putin in forma dublata (de ex.circuite analogice)

In functie de cerintele de disponibilitate impuse, se vor realiza criteriile de comutare 2 din 3 (acolo unde este cazul, va fi integrat si principiul de diversitate a emitatoarelor). Eventual, va fi realizata o logica de comanda cu mai multe canale.

Reason: The configuration of measurement and control protective equipment should be simple and comprehensible. Measurement and control protective equipment is never or only very occasionally modified when in operation.In a processing plant, only a few items of measurement and control equipment are implemented as measurement and control protective equipment. Where use of other technologies is intended this must be discussed with the responsible Petrom OMV measurement and control project manager.The Fail-Safe principle based on state-of-the-art technology must be applied where measurement and control protective equipment is used.

Where the Fail-Safe principle cannot be applied the equipment must be duplicated (analogue circuits, for example).

Depending on availability requirements, activation criteria must be implemented in 2 out of 3 circuits (where feasible, also accompanied by a range of sensors). The control logic may need to be implemented in several channels.


4.0 SCHEME SEMNALIZARE SI BLOCARE

4.1 Generalitati

Pentru montajele de alarma, comanda si blocare se va utiliza un sistem fara contacte

4.0 HARDWIRED CONTROL SYSTEM

4.1 General

A solid state system must be used for the alarm, control and blocking circuits.

Exceptii: - Intrari butoane de oprire in caz de urgenta - Intrari cu contacte releu pentru separare potential

Exceptions: - inputs for emergency off switches - outputs with relay contacts for potential separation

Utilizarea altor tehnologii va fi convenita cu responsabilul de proiect pentru electric si automatizari Petrom OMV.

The intended use of other technologies must be agreed on with the Petrom OMV measurement and control project manager.

In teren (zona expusa la explozii), se vor folosi de regula butoane inductive, tip de constructie cu fanta, cilindrice sau inelare, conform DIN VDE 0660 partea 212 in varianta Fail-Safe.

In the field (Ex area) Fail-Safe inductive switches of slot, cylinder or annular type must generally be used in accordance with DIN VDE 0660 part 212 in varianta Fail-Safe.

In caz de alarma sau deconectare, butonul inductiv va fi acoperit de o placuta de actionare ceea ce inseamna dezactivare (semnal 0). Daca acest lucru nu este posibil, din cauza montajului mecanic, se vor folosi butoane inductive inverse.

In the event of an alarm or shutdown the inductive switch must be covered by the switch flag, i.e. suppressed ("0" signal). If this is not possible due to the mechanical arrangement then inverse inductive switches must be used.

In statia de comanda (zona neexpusa ricului de explozii) se vor folosi contacte de releu capsulate.

Encapsulated relay contacts should be used whenever possible in the control room or switchgear house (Ex-free zone).

Pentru toate intrarile care declanseaza o deconectare va fi prevazut un asa numit intrerupator de suntare pentru mentenanta.

A service bypass switch must be provided for all inputs that trigger a shutdown.

Aceasta suntare nu trebuie sa dezactiveze circuitul de semnalizare.

This bypass must not render the feedback circuit inoperative.

Exceptie: Butoanele de oprire in caz de urgenta si dispozitivele de declansare pentru dispozitivele primare de protectie din Clasa A nu au voie sa fie suntabile.

Exception: it must not be possible to bypass emergency off switches and tripping devices for class A primary protective equipment.

Pentru 2 utilaje paralele vor fi prevazute dispozitive de decuplare separate, cu exceptia cazurilor oprire in caz de urgenta; in cazul a 3 sau mai multe utilaje paralele (utilaje de rezerva), se va realiza un sistem de decuplare 2 din 3 comun.

With 2 parallel machines, separate sensors must be provided for shutdown with the exception of the "emergency off" if necessary; with 3 or more parallel machines (reserve machines) a common shutdown in 2 out of 3 must be implemented.

Observatie: Altfel, in cazul defectarii unui dispozitiv de

Note: Otherwise, if an activation sensor develops a


declanare, nu va mai fii disponibil nici un utilaj de rezerva.

fault no genuine reserve machine will be available.

Sistemele temporizate asigurate la defectarea componentelor trebuie sa fie astfel executate incat, in cazul caderii sursei de alimentare cu tensiune, functionarea sa poata fi reluata dupa remedierea defectului, fara a fi nevoie de o interventie manuala.

Timers with failsafe components must be manufactured in such a way that full functionality is available once the power supply is restored following a power failure without requiring manual intervention.

Sistemele de siguranta trebuie sa fie asigurate impotriva reanclansarii accidentale (automate).

It must be ensured that safety circuits cannot be unintentionally (automatically) switched back on.

Pentru urmatoarele semnale vor fi prevazute iesiri la un sistem de inregistrare alarme in timp real: - pentru fiecare semnalizare individuala; - pentru toate butoanele respectiv contactele de comanda care influenteaza o comutare; - pentru toate intrerupatoarele de suntare de mentenanta; - pentru toate comenzile de comutare care ies in afara; - pentru toate procesele operative interne temporizate de ex. derularea ventilatiei preliminare a unui cuptor.

Outputs to a real time alarm printer system (RTAP) for the following signals must be provided: - for each individual signal - for all switches or switch contacts that affect a circuit - for all service bypass switches

- for all outgoing control commands

- for operative internal time lapses such as the pre-aeration sequence for a furnace

ANEXA 1 RAFINARIILE OMV Schwechat/PETROM

Constructia mecanica a dulapurilor

In realizarea dulapurilor, in dotarea de baza, trebuie sa nu se depaseasca 70 % echipare (echipamente) cu 20% rezerva cablata

Rack-urile vor fi in tehnica 19", cartelele electronice in format simplu Europa.

Rack-urile din dulapuri vor fi prevazute cu rame rabatabile.

Cartelele de intrare (Ex)i vor fi montate in rack-uri separate, in partea de sus a dulapurilor.

Sinele portante pentru borne trebuie sa fie concepute pentru o echipare 100% a dulapului.

Sinele portante pentru borne (Ex)i (X1) trebuie sa fie prevazute numai cu borne (Ex)i.

Pentru partea (Ex)i vor fi prevazute canale de cablu separate..

Se vor monta numai bornele necesare pentru capacitatea comandata plus pentru o echipare de rezerva de 20%.

La rack-urile (Ex)i vor fi cablate toate sloturile pana la regleta de conexiuni [partea (Ex)i]. Punctele de lipire pe stecher vor fi izolate din fabrica cu un furtun contractil.

Cartelele pentru comenzi vor fi montate separat de cartelele pentru alarme.

Cartelele pentru tensiuni 60 V vor fi montate in rack-uri separate, in partea de jos a dulapului. Cablurile vor fi pozate in canale proprii respectiv in furtune.

Intrerupatoarele necesare pentru intretinere si suntare vor fi montate langa unitatile de inzavorare, in zona de rezerva.

Echiparea dulapurilor va fi astfel gandita incat sa nu fie nevoie de sistem suplimentar de racire (ventilatoare).

ANNEX 1 OMV Schwechat/PETROM REFINERIES

Mechanical design of cabinet

When designing the cabinets, not more than 70 % of the basic equipment capacity with a wired reserve of 20 % may be installed.

19-inch technology must be used for the racks and single Euro format must be used for the electronic cards.

The racks must be incorporated into cabinets with swivel frames.

The (Ex)i input cards must be installed in separate racks at the top of the cabinets.

When designing the terminal mounting rails, 100 % equipment capacity in the cabinet must be assured.

Only (Ex)i terminals may be mounted on the (Ex)i terminal(X1) mounting rail.

Separate cable ducts must be provided for the (Ex)i component.

Only the terminals required for the equipment ordered plus 20% reserve equipment may be set.

All slots in (Ex)i racks up to the *(Ex)i page* terminal block must be wired. The soldering point on the connector must be insulated at the factory using shrink tubing.

The control unit cards and the alarm cards must be installed separately.

Cards for voltages greater than or equal to 60 V must be installed in separate racks at the bottom of the cabinet. The wiring must be routed in individual cable ducts or tubes.

The necessary service bypass switches must be installed next to the locking devices in the additional field.

The cabinet equipment must be arranged in such a way that heat will be sufficiently dissipated without requiring additional cooling (fans).


Protectia interna se va face separat pentru alarme si pentru comenzi.

O eventuala protectie pe grupe de componente poate fi facuta cu o siguranta cu buson filetat. Comenzile (deconectarile) inclusiv cartelele de intrare aferente vor fi astfel impartite in grupe de protectie incat, in cazul defectarii unui automat de siguranta, sa fie afectata numai respectiva inzavorare. La cartelele elctronice asigurate la defectarea componentei, frecventa de control va fi generata pe cartela

The internal fuse protection for alarms and control units must be separate.

Where group protection is required, this can be a plug fuse. All controls (cutting-out) including afferent entrance cards are to be divided into protection groups so that in case of a safety automatic machine failure, only the respective locking should be affected.

In electronic cards with failsafe components the testing frequency must be produced on the card.

Pentru cablarea interna a dulapurilor vor fi folosite urmatoarele culori pentru conductori: albastru ... Circuite electrice (Ex)i rosu ... +24 V (L+, EL+) negru ... 0 V (L-) maro ... Tensiuni > 60 V gri ... Inzavorari,

comenzi violet ... Alarme

The following colours must be used for the internal cabinet wiring:

blue ... (Ex)i circuits red ... +24 V (L+, EL+) black ... 0 V (L-) brown ... Voltages > 60 V grey ... Locking systems, control

systems violet ... Alarms

Regletele de conexiuni vor fi astfel marcate:

X1 Intrari (Ex)i X2 Intrari fara (Ex)i X3 Iesiri > 24 V X4 Trieri catre alte dulapuri X5 Iesiri pana la 24 V X7 Iesiri la sistemul EAD X8 Rezerva X9 Semnale sistem (HQ, LQ, LP etc.)

The terminal blocks must be labeled as follows:

X1 (Ex)i inputs X2 Inputs (not (Ex)i) X3 Outputs > 24 V X4 Jumpering to other cabinets X5 Outputs up to 24 V X7 Outputs to RTAP system X8 Reserve X9 System signals (HQ, LQ, LP, etc.)

Inscriptionare: Rack: Fiecare slot va fi marcat cu tipul de cartela prevazut.

Labeling: Racks: Each slot must be labeled with the intended card type.

Suplimentar - Intrarile EExi - WS - Iesirile de releu

vor fi marcate cu numarul de pozitie AMC.

Additionally, - EExi inputs - WUS - Relay outputs

must be labeled with the measurement and control position number.
