Realization of an Early Warning Technique for Abnormal Speed Fluctuations during Turbine Startup
Turbine unit is the core equipment of thermal power generation,and the startup process is divided into two ways:medium pressure cylinder startup and high and medium pressure cylinder combined startup.Taking a 320 MW turbine unit of a thermal power plant as an example,this paper analyzes the abnormal rotational speed problem during the startup process of medium pressure cylinder,and analyzes its generating principle and hazards,so as to realize fault location and diagnosis through the fault early-warning system to provide support for fault maintenance,and to improve the safety and stability of the unit's operation.
