单周控制DSTATCOM的建模及实现

Modeling and implementation of DSTATCOM based on one-cycle control

在简单分析了常见的其它的配电网静止同步补偿器(DSTATCOM)控制策略的同时,将单周控制策略引入DSTATCOM控制器设计中,先建立了其数学模型,再通过仿真验证了该模型的正确性。仿真结果表明,将所设计的单周控制器应用到DSTATCOM实验平台,该装置运行正常。单周控制策略应用于DSTATCOM控制器设计具有鲁棒性高、对系统频率偏差不敏感、控制简单等优点。

In order to apply one-cycle control strategy to controller of DSTATCOM （distribution static synchronous compensator） controller. While other common control strategies of DSTATCOM were analyzed simply,one-cycle control strategy was introduced to design DSTATCOM controller. Mathematical model was created, and it was shown that the model was correct by the simulation result. The one-cycle controller was apphed in the DSTATCOM experimental platform and the device operated normally. It is shown by the simulation and experiment results that one-cycle control strategy used to DSTATCOM controller design has the advantages such as good robust, being not sensitive to the system frequency deviation and simple control.
