摘要
基于模块化多电平换流器的柔性直流输电技术以其在功率控制、潮流反转、无功补偿等方面的诸多优势,必将成为未来输配电系统的重要组成部分。但是当系统电压等级较高时,所需开关器件可能会成千上万,传统仿真平台完成不了如此庞大的仿真任务,更不能满足工程测试需求。针对该问题,文中设计了一种针对柔性直流输电系统的实时仿真平台,以实时仿真器RT-LAB为基础,配以高速光纤通信接口与被测系统进行数据交互,运用半实物仿真技术完成系统测试。该平台已用于舟山工程极控系统(PCP)和阀控系统(MVCE)的测试,试验结果及工程应用表明,该仿真平台能够完成阀控系统和极控系统实时全功能仿真验证,满足实际工程测试需求。
Because of its many inherent advantages in power control, power reversal, reactive power compensation and so on, flexible HVDC system based on modular multi-level converter will become an indispensable component of transmission and distribution systems. But with the voltage level getting higher and higher,the number of switching devices of flexible HVDC system will be thousands. The traditional simulation platform has been unable to meet the requirements of simulation and engineering test. To solve this problem, this paper presents a real time simulation platform for this flexible HVDC system. It is based on RT-LAB, exchanges data between RT-LAB and under test systems with high-speed fiber-optic communication interface and completes systems test using semi-physical simulation technology. This platform has been applied in Zhoushan PCP and MVCE test. The test results and engineering application show that this real-time simulation platform can well complete the verification of actual project MVCE and PCP, and can meet the actual engineering test requirements.
