摘要
文章建立了静止同步补偿器在ABC三相坐标系下的数学模型,再通过PARK变换将ABC三相坐标转化为dq旋转坐标下的状态空间模型,并针对此系统采用一种双幂次趋近律滑模控制,搭建Matlab/simulink仿真模型,仿真结果表明在双幂次趋近律滑模控制器的控制下,静止同步补偿器具有较好的鲁棒性,其系统稳定性较好,验证了控制策略的正确性和有效性。
In this paper, state space mathematical model of STATCOM are firstly established under ABC three-phase coordinate system, and through the PARK transformation the ABC coordinates are further converted into dq rotating coor- dinates. Then, a simulation model of the system combed with a sliding mode control using double power exponential reac- hing law is built on Matlab/simulink platform. The simulation results show that with the novel control strategy STATCOM system has good robustness and stability which verifies the correctness and validity of this method.
