摘要
电压源型高压直流输电(VSC-HVDC)技术是在传统直流输电基础上发展起来的一种新型输电技术。针对VSC-HVDC系统具有良好的可控性、紧凑的模块化设计、容易构成多端直流系统等特点,阐述了其工作原理及动态性能。同时,探讨了100 kV、200 MVVSC-HVDC输电系统故障的动态性能分析,并采用Matlab/Simulink进行了仿真试验。试验结果证实了该系统在有功与无功变化以及在故障条件下具有性能良好和解耦控制有效的特性。
VSC-HVDC is a new type of power transmission technology developed based on traditional HVDC. Aiming at the features of VSC- HVDC system, e. g. , good controllability, compact modular design and easy to construct multi-terminal DC systems, ere, the working principle and dynamic performance are described. Meanwhile, dynamic performance analysis on the faults of 100 kV and 200 MV VSC-HVDC transmission systems is investigated. The simulation results by using Matlab/Simulink verify that the system possesses good performance and effective decoupling control under active and reactive power variations and fault conditions.
