摘　　要：为了解决电力系统励磁控制实际应用中的问题,利用先进的数字信号处理(DSP)技术,结合理论研究,探索了先进的控制手段对于电力系统安全稳定运行性能的改善情况,介绍了改进后的分散非线性励磁控制规律、基于DSP的控制器电路设计和相关的软件算法以及动模试验情况。动模试验结果表明,基于DSP的新型励磁控制器的软硬件完全满足电力系统实时控制的要求,新的分散非线性励磁控制(DNEC)与传统的比例积分微分的PID控制相比对于改善系统的稳定性具有更优的控制性能。Excitation control is an economic and efficient approach to maintain the voltage, improve static and dynamic stability, and enhance network transmission capability in power systems. A decentralized nonlinear excitation control (DNEC) strategy based on DSP was developed to solve stability problems in large power systems. The powerful digital signal process ability enables the excitation controller to implement complicated control algorithms in real time to improve the quality of the electricity power supply. Dynamic simulation results show that the DNEC method improves voltage regulation precision and the static and dynamic stability in power systems in comparison with the traditional PID method.
