As an advanced control tool for the steam turbine,the perfect function and performance stability of DEH control system is important to the safety and economic operation of the turbine. This paper analyzed the application of the DEH control system of two 25 MW turbine generator unit in the Liaoning Diaobingshan Coal Gangue Power Gener-ation Limited Liability Company and found the causes of defects during the operation of the DEH control systems,and then proposed the corresponding improvement measures. After a series of related transformation,the stability and relia-bility of the control system had been enhanced,and the unit outages caused by the failure of the control system were completely eliminated.
