摘要 在变结构控制理论的基础上 ,设计了一种基于神经网络的电力系统稳定器 (NNPSS)。利用BP神经网络对系统的状态进行辨识 ,通过对网络的训练 ,使神经网络能对不同的运行状态及扰动产生相对应的附加励磁控制。仿真实验证实了神经网络电力系统稳定器的可行性 ,所设计的NNPSS有效改善了电力系统的稳定性。 This paper presents a novel power system stabilizer based on neural network(NNPSS).Based on the theory of varible structure control,the NNPSS trained can identify the conditions of the generator after disturbances and thus give the optimal control.Simulations shows that the NNPSS can improve the dynamic and the transient stability under various conditions.
