Characteristic Analysis and Parameter Design of Output LCL Filter in D-STATCOM
摘要
Abstract
The parameters of output filter in distribution network STATCOM （D-STATCOM） greatly affect the attenuation of switching harmonics and the performance of the system. This paper analyses the characteristics of LCL filter from the aspects of the fundamental inductor voltage drop, the reactive power compensation ability of STATCOM, the attenuation of switching harmonics, and filter resonant frequency. Then a parameter design method of LCL filter is proposed based on these constraints. In addition, the power loss of the filter is greatly reduced by connecting a small inductor in parallel with the damping resistor in this paper. The simulation results show that the designed LCL filter parameters have good filtering effects, and the filter has larger pass-band width, making D-STATCOM to have the function to compensate some harmonics关键词
