酒泉-湖南±800kV特高压直流工程在特殊工况下的控制特性研究
摘要：基于酒泉-湖南±800kV特高压直流控制系统出厂联调现场经验,阐明了GAMMA控制器、电压控制器与电流控制器的限幅配合方式及其得以实现的参数配置,探讨了电压控制器对电压偏高和电压偏低的灵敏度及GAMMA控制器附加电流项的作用机制,研究了极启动与阀组退出时逆变侧分接头档位逆向变化的成因,深入剖析了特高压直流所配各控制器在极启动与停运、阀组在线退出、交流系统电压波动、极间电磁干扰等特殊工况下的控制特性及其分析方法。论文分析方法与研究结果有助于剖析特高压直流系统在复杂工况下的控制特性,具有较强的实用性和普适性。
Abstract:Based on the application experience of joint debugging on the control system of Jiuquan-Hunan ?800 k V UHVDC project, the limited amplitude fitting method and its realization principle of parameter setting of the GAMMA controller, voltage controller and current controllerare clarified, the sensitivity of high voltage and low voltage for the voltage controller and mechanism of the appended current factor of the GAMMA controller are discussed, the internal mechanism of the adverse change of transformer taps under the pole-starting and valve-exiting is investigated, and the control characteristics and its analysis methods of UHVDC under such special conditions as starting/stopping a pole, exiting a valve on-line, the voltage fluctuation of the AC system and the electromagnetic interference between poles are deeply studied.The analysis method and research results are helpful for analyzing the control characteristics of UHVDC system under complex conditions, and have strong practicability and universality.
