摘　　要：针对传统静止无功补偿器(static synchronous compensator-STATCOM)只能补充无功功率的不足,对直流侧并联蓄电池储能系统(battery energy storage system-BESS)的改进装置进行了研究,从而实现有功无功功率的双重控制。首先对STATCOM-BESS工作原理和数学模型进行简要介绍,之后对四象限模式的运行特性进行重点分析,并研究了基于电压空间矢量(SVPWM)有功功率无功功率独立控制的电流解耦控制技术。最后在MATLAB/Simulink中搭建STATCOM-BESS模型进行仿真分析,仿真结果显示装置在快速实现无功功率补偿的同时也可以实现有功功率的控制,并具有良好的动稳态特性,因此验证了理论分析的正确性和控制方法的有效性。In view of the disadvantage of the traditional replenishing the reactive power, the improved system of the static synchronous compensator （STATCOM） for only D.C. side-parallel battery energy storage system （BESS） was studied in this paper to achieve the dual regulation of both principle of the STATCOM-BESS was described briefly and active and reactive power. At first, the operating a mathematical model was derived. Besides, the operating characteristics of the four-quadrant compensation model were analyzed particularly. Then the current decoupling control techniques were studied based on the active and reactive power independent control of the SVPWM. Finallythe STATCOM-BESS model was built in the MATLAB/Simulink and simulation analyses were made. The simulation results showed that the proposed model could precisely and quickly control both the active and the reactive power control and had excellent dynamic and steady state characteristics, which verified the accuracy of the theoretical analysis and the effectiveness of the proposed SVPWM control method.
