摘　　要：静止同步补偿器(STATCOM)具有从感性无功功率到容性无功功率连续调节的功能,在电力系统中引起了广泛的关注。从静止同步补偿器的基本结构和工作原理出发,对STATCOM电流控制策略以及无功检测技术做了简单介绍,在瞬时无功功率理论的基础上对传统无功检测方法进行了改进,弥补了传统检测技术的局限性。采用直接电流控制和改进的无功检测方法在Matlab/Simulink仿真工具下建立了STATCOM的仿真模型,并对感性负载和容性负载分别进行了仿真。仿真结果表明,所设计的STATCOM具有良好的补偿效果。Owing to the continuously adjustable function from inductive reactive power to capacitive to capacitive reactive power, static synchronous compensator（STATCOM）has attracted wide attention in the power system at present. From the basic structure and working principle of static synchronous compensator, a simple introduction of control strategy of STATCOM current and reactive power detection technology was proposed. Through improving the traditional method of reactive power detection based on instantaneous reactive power theory, the limitations of the traditional detection technology were made up. Under the Matlab/Simulink simulation tool, direct current control and improved of reactive power detecting methods were used to establish the simulation model of STATCOM, and the perceptual load and capacitive load were simulated respectively. The results show that the design of STATCOM has good compensation effect.
