摘要
本文分析了轻型直流输电VSC-HVDC的工作原理、数学模型和电网电压矢量定向VOC控制策略,推导了电流内环的前馈解耦机理。基于Matlab仿真平台,搭建了2000MVA的VSC-HVDC轻型直流输电仿真模型,实验结果表明通过PQ解耦,实现了潮流控制、无功控制和两不同频率的交流电网互联等。
The working principle, mathematical model and VOC control strategy of VSC-HVDC are analyzed and the principle of feedfor- ward decoupling of current inner loop is deduced in this paper. Based on the Matlab simulation platform, the 2000MVA VSC-HVDC light DC transmission simulation model is established. The experimental results show that the power flow control, reactive power control and two different frequency AC power interconneetion are realized by PQ decoupling.
