摘要
随着我国坚强智能电网的建设,以及风能、太阳能等清洁能源利用规模的不断扩大,柔性直流输电必将因其独有的优点成为我国电网的重要组成部分。介绍柔性直流输电系统的基本结构和工作原理。利用Matlab中的Simulink模块建立了柔性直流输电系统及其控制器的仿真模型,并在此模型的基础上进行了正常情况下的稳态仿真及暂态故障的仿真。仿真结果表明建立的模型及其控制策略可靠有效,有一定的工程实用价值。
As the construction of Strong Smart Grid and the large-scale utilization of clean energy, light high voltage direct current transmission （HVDC-Flexible） will certainly be an important part of the power grid of our country. In this paper, the basic structure and operating principle of HVDC-Flexible are introduced. Besides, the model of HVDC-Flexible and its controller are established by using Matlab/Simulink software. On the basis of this model, the simulation of steady state and transient fault is conducted. The results of the simulation indicate that the model and its control method are effective and valuable in engineering application.
