【摘要】：未来柔性直流输电技术大容量、高电压、远距离的发展趋势,对现有的柔性直流仿真建模技术提出了更高的要求。为了建立更符合控制保护装置测试需求的大容量、高电压、远距离柔性直流实时仿真模型,提出了适用于各种子模块拓扑结构且能灵活定义模块级故障的模块化多电平换流器(MMC)等效建模方法,采用基于现场可编程门阵列(FPGA)技术实现灵活柔性直流换流器算法,通过双向高速通信板卡GTFPGA在实时数字仿真器(RTDS)中实现灵活自定义的柔性直流MMC仿真建模,为未来含新型子模块拓扑结构的大容量、高电压、远距离柔性直流工程的控制保护特性研究及其闭环试验,提供有效的实时仿真试验系统和重要的仿真技术支持。
[Abstract]:In the future, the development trend of high capacity, high voltage and long distance flexible DC transmission technology puts forward higher requirements for the existing flexible DC simulation modeling technology. The remote flexible DC real-time simulation model is presented. An equivalent modeling method for modularized multilevel converter (MMC) is proposed, which is suitable for the topology of various sub-modules and can define module level faults flexibly. The flexible DC converter algorithm is realized based on FPGA (Field Programmable Gate Array) technology, and the flexible DC MMC simulation modeling is realized in real-time digital simulator by GTFPGA, which is a bidirectional high-speed communication card. It provides an effective real-time simulation test system and important simulation technology support for the research of control protection characteristics and closed-loop test of the future high-capacity, high-voltage and long-distance flexible DC engineering with new sub-modules topology.
