摘　　要：孤岛运行作为云广特高压直流输电工程的设计运行方式之一,能够有效提高南方电网的稳定水平,但是存在较严重的机组间相互作用引起的小湾机组调相运行问题。建立了将电厂调速器控制系统、励磁系统、监控系统接入RTDS实时仿真系统形成云广直流孤岛分析的仿真试验平台,该仿真平台具有较高的仿真可信度,从调速器控制逻辑与参数在直流双极闭锁甩负荷后的调节规律的角度分析了小湾电厂机组调相运行的机理。Abstract ： The islanded operation, one of the designed normal operation modes for Yunnan-Guangdong UHVDC transmission system, can increase the stability of China Southern Power Grid remarkably. But as the system is in the islanded operation mode, the hydro- generators in Xiaowan power plant could be in a compensating mode due to the interactions between generators. Building up a RTDS simulation platform which includes the governors, excitation system and monitoring system, and thus has relatively high simulation credibility, this paper analyzes the mechanism of Xiaowan generators compensating mode in view of the governor control logic and parameter regulating after the system rejecting load when bipolar latch happened.
