摘要
提出一种以PLC为工作平台的多指标非线性励磁控制器,理论上,该控制器能够在有效控制发电机端电压的前提下提高系统的动态稳定性。介绍了基于西门子PLC的励磁控制器的实现方法。仿真和试验结果表明,该控制器实现了对系统动、静态性能的综合协调,从而提高了系统的整体性能。
A kind of multi-index non-linear excitation controller is proposed based on PLC.In theory,this controller can improve the dynamic stability of the system on the premise of controlling the end voltage of the generator effectively.The thesis introduces the realization method of excitation controller based on Siemens PLC.Simulation and test result show that this controller has realized the comprehensive coordination of dynamic and static performance of the system,thus has improved the whole system performance.
