A quick overview of the ControSteam™ Steam Turbine control system
The ControSteam™ consists of:
- 2 MFC1000 or MFC3000 cell heads (master/slave)
- 3 CE1500 field controllers (in a 2-out-of-3 architecture)
- 2-out-of-3 overspeed rack
- 2-out-of-3 safety relay
- 1 clock
- 1 engineer station.
ControSteam™ PLC and cards
It mainly consists of Some specific electronic cards have been produced by Alstom®:
- MFC1000 / MFC3000: The ALSPA™ MFC1000 / MFC3000 is a real-time Multi-Function Controller. MFC1000 provides the communication of control data between the field network and the control room. This controller embeds application programs for sequence control and loop control.
- MPM123: In the ALSPA™ ControSteam™ product, the MPM123 is a safety module (IEC 61508 – SIL3 in 2oo3 configuration) used for machine protection. The MPM123 module can be used as autonomous in the ALSPA™ architecture. It provides threshold detection on critical measurements by “Trip relay”
- SPC160: Hence the module is a digital servomotor positioner which can be used in STG820 1/1, 2/2 and 2/3 architectures. It is made up of 3 electronic cards, i.e. ISPC1/IP160, ISPC2/AS118 and MACO/UT145, which are mounted in a 8035 type housing
- Other cards like PS3300, ZF0001, ZF0000, DS1119, AI4632, AO4632, AT4222, DI9371, DI6371, DO8332, CP1485-1, PS9400, X20HB8884, X20HB888.
ControSteam™ maintenance tools
- Controcad™ (CCAD) is the full package which allows to modify and compile the ControSteam™ program. It also allow to record the signals through the “evlog”, these are capture blocks that are triggered manually or on a signal level.
- Visurec is used to configure :
- SPC 160 to perform commissioning tests, like position loop test
- MPM123 to configure input parameters and Trip threshold, tune scaling function.
