摘要

分布式静态补偿器(DSTATCOM)是一种基于多级级联H桥(CHB)逆变器的分布式静态补偿器，用于电力系统的谐波抑制和无功补偿。这种基于CHB的逆变器提供低谐波失真，减少开关数量和抑制开关损耗。它还有助于提高功率因数和消除总谐波失真(THD)。比例积分(PI)控制用于电容直流电压调节。采用移电平PWM (LSPWM)技术分析了CHB逆变器的性能。研究了一种用于11kV配电系统并联补偿的CHB逆变器。仿真结果通过MATLAB和Simulink软件得到。

Cascaded H-Bridge Five Level Inverter forHarmonics Mitigation and Reactive PowerControl

Distribution Static Compensator (DSTATCOM) which based on multi-Level Cascaded H - bridge (CHB) Inverter for mitigation of harmonics and compensation of reactive power in Power System. This CHB based inverter provides low harmonic distortion, reduced number of switches and suppression of switching losses. It also helps to improve the power factor and eliminate the Total Harmonics Distortion (THD). Proportional and Integral (PI) control is used for capacitor dc voltage regulation. A level shifted PWM (LSPWM) technique is used to analyse the performance of CHB Inverter. A CHB Inverter is considered for shunt compensation of 11kV distribution system. The results are obtained through MATLAB & Simulink software.
