摘要
为了全面系统地认识配电系统无功补偿器(DSTATCOM—Distribution Static Synchronous Compensator),研究其工作特性,本文在分析DSTATCOM工作原理的基础上对其进行了深入的理论分析并建立它的数学模型。采用MATLAB仿真软件对该装置的工作过程进行了仿真研究,并在实验室搭建了无功补偿装置的试验平台。从仿真结果可见,本文分析的工作原理和建立的数学模型是正确的;从试验波形可见,DSTATCOM不仅能够动态调节无功功率,而且其响应速度非常快,对无功功率的调节是连续无级差的,补偿效果是明显的。
In order to study the characteristic of Distribution Static Synchronous Compensator, Its depth theoretical analysis and ＂the establishment of the mathematical model are done on the basis of analysis of its work principles. The simulation studies of the work process are carried out with MATLAB and the test platform of DSTATCOM is structured in the laboratory. It can be seen from simulation results that, the working principle and the establishment of mathematical model of DSTATCOM in this paper are correct, as well as from the test wave that DSTATCOM can absorb reactive power, and its response speed is very quick. The reactive power regulation of DSTATCOM is no class difference and its compensation effect is obvious.
