摘    要:介绍了静止无功发生器的工作原理及控制方法,提出了一种静止无功发生器控制器的设计方案,给出了该控制器设计过程中需注意的主、分控制器通信问题,显示CPLD收发数据的消抖问题,IGBT上下桥臂的短路问题,程序跑飞问题及相应的解决措施。该控制器基于滞环瞬时比较控制原理,采用主控制器+分控制器的设计方式,且主、分控制器均采用DSP+CPLD的结构,提高了静止无功发生器控制器的运算速度和实时性。

关 键 词:静止无功发生器  控制器  滞环瞬时比较控制  CPLD  DSP

Abstract:The paper introduced working principle and control method of STATCOM and proposed a design scheme of a STATCOM controller.It also gave some problems and corresponding solutions including communication between the master controller and the slave one,jitter elimination in process of data transceiving of displaying CPLD,short circuit in bridges of IGBT and procedures fleet.The controller is based on the theory of hysteresis instantaneous comparison control and uses a mode of master-slave controller.The master controller and the slave one both adopt DSP+CPLD structure so as to improve operation speed and real-time performance of the STATCOM controller.
Keywords:STATCOM  controller  hysteresis instantaneous comparison control  CPLD  DSP
