摘　　要：针对电力系统输出控制的特点,将电压的稳定作为控制目标,在分析线性系统性质的基础上得到了拟线性控制系统的模型,由于神经网络具有处理非线性的不具有精确模型的问题。通过对单入单出的系统作分析和变换,在神经网络作为逼近的输入元素,将得到的拟线性控制系统运用到电力系统的稳定中去,通过对单机无穷大系统作仿真,表明设计的控制系统具有很好的电压稳定性效果,验证了拟线性系统设计的有效性。The transient stability of the power system is the most important in the normal operation, according to the characteristics of output control. The model is designed after the analysis of the linear control in the system. An ANN strategy is proposed which has the power ability to deal with the nonlinear problern without the accurate model. After analyzing and calculating the SISO system, based on the ANN system, a quasi - linear control system is designed to operate on the power system stability. The simulation results show the stability of power system can be enhanced significantly by using the proposed quasi - linear system.
