安装在500kV二滩水电站输电通道上洪沟静止无功补偿系统SVS(Static Var System)、陈家桥静止无功补偿装置SVC(Static Var Compensator)和万县变电站SVS是我国第一批国产500kV变电站SVS。2006年7月洪沟枢纽变的SVS首先投运,这套SVS是当时我国电网中运行的最大容量的国产SVS。重点介绍:应用SVS技术,研究制造集成的我国第一套电力系统输电通道枢纽变大容量SVS;对SVS进行的重现电力系统电压,长时间(42h)实时数字仿真RTDS(Real Time Digital Simulation)稳态仿真试验,以及RTDS动态和暂态仿真试验;在运行的川渝电网上进行的SVS的电力系统大、小干扰试验;和SVS的运行情况。
The Static Var System (SVC) installed in the transmission channel of Ertan Hydropower Station of 500 kV and the Static Var Compensator (SVC) of SVC and the SVS of Wanxian Substation are the first SVSs of China-made 500 kV substations. In July 2006, the SVS at the flood ditch hub was first put into operation. This SVS is a domestic SVS with the largest capacity in operation in China’s power grid at that time. Highlights: The SVS technology was applied to research and manufacture of integrated China’s first power system transmission channel hub with large capacity SVS. The SVS was used to reproduce the power system voltage, long time (42h) real-time digital simulation RTDS (Real Time Digital Simulation) Steady state simulation test, RTDS dynamic and transient simulation test, big and small power system interference test of SVS on the running power grid of Sichuan and Chongqing, and the operation of SVS.
