In view of high reliability characteristics, strong adaptability and low cost of the digital simulation method, the mathematical model of the Hydraulic Turbine Governing System is established, and dynamic and static characteristics of Hydraulic Turbine Governing System are simulated by using digital thought. To optimize system performance, system speed is compensated by the method of direct torque compensation, which is based on digital simulation of hydraulic turbine governing system. This system drives synchronous generator to simulate the hydro electric power generation system. Experimental results show that the digital simulation system can more accurately simulate all kinds of power system of characteristics.
