Client: Heating plant Malesice
Location: Malesice, Prague
Project description
ZPA Industry a. s. is partner at Prazska Teplarenska Inc. since 1991. During the years the company participated on number of projects in control system reconstruction, field instrumentation, control cabinets deliveries.
Technological part TMA2
Four steam boilers K11-14 for brown-coal burning with capacity 160t/hour ( in 1995 two boilers were put out of the service, two boilers were reconstructed for black coal burning and output increased to 180 t/hour of steam.
Two backpressure turbines 55MW with five feeder points, third feeder point has steam pressure of 1,0 Mpa. System can operate during entire heating season.
Technological part TMA3
Two hot water boilers K21, 22 burning gas, output power 100GJ/hour. Operating as peak capacity during entire year.
Control system
During 1992-98 the company implemented control system GE Fanuc 90-70, 90-30 in combination with visualisation software Cimlicity HMI Plant Edition to control technological part TMA2.
Systém architecture is based on redundant DCS stations GE Fanuc 90-70 connected with redundant Cimplicity HMI Servers. Cimplicity HMI Servers process data created by DCS system and provide this data to operator’s station for visualisation and control.
Control system architecture for TMA2, TMA3:
8x PLC GE 90-70 (redundancy)
6x PLC GE 90-30 (non redundancy)
1x OPC connect control system Honeywell
2x Cimplicty HMI SERVER K11, K12 ALPHA (Server Redundancy, SQL database);18000 I/O
2x Cimplicty HMI SERVER K21, 22; 1500 I/O
14x Cimplicity HMI Viewer – Operator workstation
