基于DSP的双CPU冗余静止同步补偿器控制系统的设计及其动模试验

The Design of a STATCOM Controlling System with Redundant CPU Using Two DSP and Its Dynamic Experiment

结合Kvar静止同步补偿器的研制,介绍一种STATCOM装置的拓扑结构及其基于DSP的双CPU冗余控制系统的软硬件设计,提出一种基于变结构神经网络模糊控制的内环控制和PI外环控制的双闭环控制结构,试验确定了逆变器的开关频率,试验模拟冲击负载下的单负荷-无穷大系统中STATCOM及其控制系统对系统无功功率的补偿效果,结果表明该装置能够维持负载母线电压的稳定性。

Combined with the development of a Kvar STATCOM equipment based on IGBT power module, One kind of the development scheme is offered . as well as its hardware structure based on DSP with redundant CPU and design of control sol, ware for the apparatus. It puts forward a non - linear controller with a PI external - ring con,roller and an innerring controller using variable structure neural network fuzzy control algorithm model. At the end the results of dynamic experiment are given, which confirm the switching frequency and the performance of this equipment.
