云广孤岛运行方式RTDS试验平台的构建及研究

Construction and Analysis of the RTDS Testing Platform for Islanding Operation of Yunnan-Guangdong UHVDC System

构建了云广直流和兴安直流联接实际控制保护装置的RTDS试验系统,对云广特高压直流在孤岛运行方式下,各种故障下送端系统的动态特性进行了试验研究。结果表明,该RTDS仿真试验系统有足够高的仿真精度,满足对云广特高压直流孤岛运行方式下系统动态特性仿真研究,以便为云广特高压直流孤岛运行方式下安稳策略制定提供技术支持。

A real time digital simulation （RTDS） testing system in which both the Yunnan-Guangdong UHVDC system and the Xing＇an HVDC system are connected to their real control and protective devices, is established to study the dynamic performance of the sending-terminal AC system of Yunnan - Guangdong UHVDC system under islanding operation mode. The results show that the RTDS testing system has simulation accuracy high enough to be adapted for simulation study of the UHVDC system so as to provide technology support to the security and stability strategies establishment under the islanding operation mode.
