ולידציה – Design Specification – DS
The Design Specification -DS is part of the validation documentation that provides information necessary to complete the design of the project. This document covers only the DCS side and integration with ELT-GHS-150-T3 Gas Heater skid
DS Content
The DS is usually structured in a relatively standard fashion, with predetermined chapters and sections, where the final contents are tailored according to the type and size of the system under validation.
:The main chapters and sections of this DS are
Hardware Specification
Wiring and Electrical Cabinet Drawing
Communication and Network Design
Other Documentation
ProfiBus Monitoring Values List
Appendixes
Hardware Specification
.This section defines the required I/O allocation, according to the wiring diagram document No. P09204-020 Rev2, and 35800SIS0-N0
8 digital inputs
1 digital outputs
ProfiBus connection
Wiring and Electrical Cabinet Drawing
:This section lists the following design information
New Electrical drawing is not needed
:All I/O should be named in a standard fashion, i.e., XXXX-YYY-ZZZ, where
XXXX – 4 prefix letters which indicates the containing system; in this case, the system is PRMS
.YYY – indicates the instrument type according to Siemens naming standard – document no
ZZZ – indicates the serial continuing number
.Siemens Engineering file update is needed in Chapters18C 18D 18E. Other chapters should be examine and discussed in the FRS
.BOP PLC must be stopped during the wiring and ProfiBus module installation. Dalkia should be supply with time table
Communication and Network Design
:This section lists the following design information
.The communication used in this project is Profibus
.The Profibus communication protocol and wiring design will be provided by Siemens
.Siemens Engineering file update is needed. All communication and network chapters should be updated
Communication and Network Design
Siemens Engineering file "stand alone skids and instruments" chapter should be update; all Heater manuals and instructions should be attached to this chapter.
ProfiBus Monitoring Values List
tSP Target Setpoint – Setpoint differential CT15/14 – CT15/13
All Operator.MAIN items – To be later configured
All Operator. SYSTEM.StatusWords.Output) – To be later configured
Man Manual/Auto Mode 76 AUTO (0) – +VFD manual percents
Running Logic
start conditions
Heater valve V101 is open. – GS101 HEATER INDICATION.
Heater valve position V102 is open.
Heater bypass valve V103 is closed.
DCS 10EKA01CF001>1500m3h (indicating that at list one of the gas turbines is on).
DCS 25Barg<10EKA001CP001<45Barg (Gas pressure operation range).
All Heater trips are acknowledged and cleared.
Operator pressed "Start" from DCS.
Alarms List
All alarms from profibus
Alarm Response
Holding/Restart Logic
No alarm response from the DCS.
Disaster Recovery
Perform stop operations as in paragraph
- Power shut down
- Compressed air supply shut down
Programming Design
AS (Automation system – PLC) that will be programmed in this integration will be BOP.
The synoptic screen will be programmed and be added to the PRMS screen, as described in Appendix 1 – Synoptic Screen.
All instruments, EG valves and transmitters, will be created according to Siemens standards.
All instruments will be set to READ ONLY, except the START and STOP buttons.
Appendixes
The DS appendixes present examples of design drawings.
Appendix 1 – Synoptic Programming Design.
Appendix 2 – Chapter 18E BOP Example of Electrical Drawing (to be updated)
Appendix 3 – Example of Network Drawing (to be updated)
