| 摘 要： | 鉴于快速响应的配电网静止无功补偿器—DSTATCOM是改善配电网系统电能质量的有效方法 ,提出对DSTATCOM采用离散滑模控制 ,应用MATLAB对 10 / 0 .4kV配电网中的动态补偿进行仿真 ,并基于此研制出小容量DSTATCOM实验模型。仿真和实验证明 ,离散滑模控制策略简单易行 ,控制效果良好 ,在谐波畸变率大致相等的情况下 ,比其它控制策略更能极大地减小开关损耗。基于离散滑模控制的DSTATCOM可正确地补偿系统所需的无功功率 ,对改善电能质量可行有效。

| Abstract: | The fast response of the Distribution Static Compensator (DSTATCOM) makes it efficient solution for improving power quality in distribution systems. A new control strategy, quasi-sliding mode, is presented. By the means of MATLAB, some simulations in the DSTATCOM mode in the 10/0.4 kV distribution systems have made. Comparing with others control strategies, quasi-sliding mode can greatly decrease switching loss as far as possible. In the light of experiments and simulations, it is concluded that the quasi-sliding mode control principle not only can compensate the var of load demand but also have advantages of superiority and feasibility. |
