Design and realization of turbine valve status diagnostic system

Abstract

Abstract:

Abstract:Taking the turbine valve operation of six turbine plants in Sichuan Guangan Power Plant Company Limited as an example,the valve state diagnosis system for steam turbine is designed which is based on DEH internal hardware monitoring and communication technologies, and directly acquires DEH and servo data.The turbine valve performance and condition are judged by programming,analyzing real time and historical data.The state of the turbine valve monitoring,alarm and turbine valve test and maintenance are integrated into the man machine interface,which has a diagnostic accuracy,simplify,facilitate intuitive features.The system are timely diagnosis,accurate,intuitive and economic prominence.

Key words: Keywords:turbine, turbine digital electro hydraulic control system, vavle, diagnosis, design, implementation
