摘　　要：电力系统中常出现的谐振问题,针对传统的VT消除谐振方法存在消谐效果不明显的情况,对VT用流敏电阻型一次限流消谐器进行研究与应用分析。分析流敏电阻型一次限流消谐器构成及原理,将其应用在某区域电力系统中,通过分析,证明该方法可以有效抑制VT铁磁谐振,具有较好的使用性能与经济性能。在提高对电力系统检测能力的同时,节省其检修成本,提高经济效益。The resonance problem often occurs in power system.In view of the fact that the traditional VT resonance elimination method has no obvious harmonic elimination effect,the current sensitive resistor primary current limiting harmonic eliminator for VT is studied and applied.This paper analyzes the composition and principle of current sensitive resistor primary current limiting har-monic eliminator,and applies it to a regional power system.Through analysis,it is proved that this method can effectively sup-press VT ferromagnetic resonance,and has good service performance and economic performance.While improving the detection ability of power system,it saves its maintenance cost and brings economic benefits.
