摘要

本文重点介绍了在印度西部地区加强计划(WRSS)下，印度电网公司WR - I(西部地区- I) 1200/765/400/220千伏瓦尔达变电站安装40%固定串联补偿(FSC)的实时实际案例研究。本研究的新发现是在各种内部故障条件下，火花间隙与金属氧化物压敏电阻(MOV)根据阈值能量协同工作，这与以往一些研究工作的假设相矛盾。为了增加电力容量，满足日益增长的电力需求，在400千伏双回路赖布尔-瓦尔达线(375公里)上实施。本文通过仿真结果与实时数据的对比，重点研究了FSC对指定线路的影响。本文还详细介绍了用FSC对指定线路进行故障分析的方法。

Co-ordination of spark gap protection with MOV in EHV transmission line with FSC

This paper highlights a real time practical case study of 40% Fixed Series Compensation (FSC) installed at 1200/765/400/220 kV Wardha Substation, Power Grid Corporation of India Ltd., WR - I (Western Region - I), India under Western Region Strengthening Scheme (WRSS). The novel finding in this research work is the operation of Spark gap in co-ordination with Metal Oxide Varistor (MOV) during various internal fault conditions, according to the threshold energy which contradicts the assumptions made in some of the previous research works. For increasing the power capacity and meeting the rising power demands, it is implemented on 400 kV double circuit Raipur - Wardha Line (375 km). This paper focuses on the effects of FSC on the specified line studied by comparing simulated results with real time data. It also dwells into fault analysis aspects of the specified line with FSC.
