摘要
谐波治理是高压直流(High Voltage Direct Current,HVDC)系统的关键技术之一。本文分析了应用在HVDC直流侧的直流有源滤波器工作原理,提出了近似逆系统的控制策略。并在PSCAD／EMTDC软件平台和实际装置中进行了实践。仿真和实验样机验证了逆系统控制的可行性和有效性。控制系统稳定,滤波效果优良。
Eliminating harmonics is one of the key technologies of High-Voltage Direct Current （HVDC） transmission systems. This paper expounds the principle of the active DC filter applied in the HVDC system, and proposes an approximate inverse system control strategy. The results of both simulations based on PSCAD/EMTDC and experiments on a 50kVA HVDC system validate that the proposed control system is stable and able to eliminate the harmonics efficiently.
