Research on hydraulic power plant monitor and control system based on NC2000

This paper describes the research of NC2000 computer monitoring system in Xinjiang Xiabandi hydraulic power plant. The system adopts client/serve system structure; it realizes the remote signaling, remote measuring, remote control and real-time monitoring for the water-turbine generator set. Under the condition of single generate, Through analysis incompatibility in anti-disturbance and stability of the turbine speed governor system which controlled by PID mode, we establish the priority of parameters optimization strategy to ensure the stability, and then follow the given optimization model parameters to adjust the stability. The simulation results and the practice show that the method relieved the contradiction between disturbance and stability, it has obtained certain result. The results of debugging and operating show that, the monitoring system has high control precision, electrical analog data acquisition cycle is less than 250ms, response time is less than 1s, data transmission is reliable, maintenance is easy. It has a high technical level. Contraposing the problems exposed during the operation, this paper puts forward the corresponding solutions to the similar hydraulic power plant at automatic control, it has certain reference.
