| Abstract: | In large turbine generator of the speed for long-distance transmission system, Valve opening influence generator power and speed. Thus affect the stability of the system. Using the optimal control theory to design the valve opening the optimal controller. Through to the valve governor control simulation, research the output powerand speed characteristics of generator. The results show that the valve opening optimal control plays an important role to improve power system stability and inhibit low frequency oscillation, greatly improve the dynamic function of the system. |
