Reformation Of PLC Automatic Control System In Taipingshao Hydropower Plant

With the development of microprocessor and intranet technology, computers play a more and more important role in many aspects of industry process.This paper regards synthesizing and automatic allying control realizes highly automation, highly dependability and maintainability in the hydropower station as the design object, According to Taipingshao Hydropower plant one's own structure characteristic, use the experience of the monitoring system and PLC Automatic Control System of the domestic and international computer for reference, make the overall design plans of this hydropower station of PLC Automatic Control System. Application study on using PLC to handle automatic sequence control, active and reactive power control and operation mode control of generator within local control unit of the monitoring system for hydropower station is introduced.
