摘　　要：与传统的高压直流输电系统相比,轻型直流输电系统(HVDC Light)采用绝缘栅双极晶体管(IGBT)作为功率开关器件,能够对有功功率和无功功率进行独立的控制,具有调节迅速,稳定性高等优点。在研究轻型直流输电技术的工作原理和控制方法的基础上,设计了一个轻型直流输电系统,并在电磁暂态程序PSCAD/EMTDC环境下建立仿真模型,仿真实验结果验证了系统参数选择的合理性和控制方法的有效性。Compared with the traditional HVDC system, insulated gate bipolar transistor （IGBT） is widely used in HVDC light system. This system could control active power and reactive power in dependently, meanwhile, it has a high stability and quick adjusting process. In this paper, the system working principle and control strategy are analyzed. After that, a HVDC light system is designed and its simulating model is established under the environment of PSCAD/EMTDC. The simulating results testify the rationality of system elements and the effectiveness of control strategy.
