Abstract:

Abstract:In order to realize the automatic sequence control of air cooling system for a certain gas steam combined cycle power plant in Malaysia,the sequence start up and sequence shutdown functions for the air cooling system were designed according to the unit condition, which based on the analysis of design parameters and the control system configuration of air cooling system.In addition,a dedicated back pressure adjusting system for air cooling condenser was designed in order to ensure the safe operation of unit.Since the adoption of sequence control mode for air cooling system,the automation level of the unit was improved and the labor intensity of operating staff was reduced.

Key words: Keywords:gas steam combined cycle power plant, air cooling condenser, air cooling system, sequence control
