| 摘 要： | 配电网静止同步无功补偿器D-STATCOM是重要的用户电力设备,能够有效解决配电网中电压波动与闪变、三相电压不平衡、电网谐波污染等电能质量问题。针对配电网静止无功补偿器D-STATCOM的动态性能,用开关函数法建立了D-STATCOM的动态数学模型,然后依据瞬时无功理论对直接电流控制的D-STATCOM控制系统进行了设计。根据所建立的数学模型和控制系统,搭建了D-STATCOM的系统仿真模型,得到了D-STATCOM的动态仿真图。仿真结果表明,基于直接电流控制的D-STATCOM具有良好的动态性能。

| Abstract: | Distribution Static Synchronous Compensator(D-STATCOM) is an important electrical equipment for users.It can effectively solve the problems of distribution network such as voltage fluctuation and flicker,three-phase voltage unbalance and harmonic pollution.In this article the D-STATCOM dynamic mathematical model is built according to the instantaneous reactive power theory,and the D-STATCOM control system is designed by direct current control method.Based on mathematical models and control system described,a D-STATCOM simulation model is build.Simulation results show that,as described in this article,the D-STATCOM based on direct current control has a good dynamic performance. |
