Research on stability of excitation power system of pulse control based on time and state
摘要
Abstract
The stability and dynamic performance of the power system are crucial in the modern power grid,and a good excitation system can ensure the reliable operation of the power system.In order to maintain the stable operation of the system,a new control mode of the excitation system is proposed,that is pulse control based on time and state.The mathematical model of the single-machine infinity excitation system is constructed,and the pulse control scheme under the two conditions of time and state is expounded.The disturbance caused by external interference is considered,and the pulse control in the sense of input-state-stability(ISS)is established.The Lyapunov-like function is used to prove that the excitation power system can achieve exponential stability and input state stability under pulse control based on time and state.The effectiveness and correctness of the proposed method and the proposed control strategy are verified by Matlab simulation experiments,and compared with the synovial control methods in relevant literature.The results show that the designed pulse control has the advantages of fast response speed and low cost,and the state-based pulse control can significantly improve the system performance.关键词
