静止无功补偿的多DSP控制器研制与应用

无功补偿控制器是影响静止无功补偿(SVC)动态性能的关键环节。基于多DSP系统,给出了无功补偿控制器的实现结构,讨论了SVC无功控制器CPU的功能实现、晶闸管控制电抗器(TCR)控制CPU的同步触发与晶闸管(SCR)导通检测功能的具体实现技术及CPU间的信息交换技术。在该系统中,多个CPU分工协作,分别完成SVC采样与控制的计算,TCR移相触发和SCR导通监测,各CPU间通过双口RAM和VME总线进行信息交换。试验结果表明,该系统具有计算速度快,响应速度快,动态性能好等优点。

Development and Application of Multi-DSP SVC Controller

The reactive power compensation controller is a key component which affects the dynamic performance of SVC.Based on multi-DSP system,this article gives implementation structure of the controller,and discusses function realizations of SVC reactive power controller CPU,TCR synchronous triggering CPU and SCR conduction testing.Then it gives the testing results.In this control system,multiple CPUs cooperate based on division of function such as cal-culation of SVC sampling & control,TCR phase shifting & triggering and SCR conduction monitoring,high speed communication between CPU by using the VME bus through the two port RAM.The results show that the system is featured by high-speed calculating,fast response and good dynamic performance.
