配电网 TV 高压熔断器熔断影响因素的分析OA北大核心
The analysis on the influence factors of TV fuses blowing in the distribution network
针对配电网时常发生的TV高压熔断器熔断的事故,分析了造成事故发生的主要原因为铁磁谐振和低频非线性振荡。利用ATP-EMTP建立仿真模型,对母线出线总长度、TV励磁特性、TV直流电阻和单相接地过渡电阻这4种TV高压熔断器熔断的主要影响因素进行仿真分析,得出了它们对TV高压侧过电流和系统谐振状态影响的一般规律。总结了现有的几种TV高压熔断器熔断的防治措施的优缺点,并对其消谐效果进行了仿真对比分析。
For frequent electromagnetic voltage transformer ( TV) fuses blowing accident in the distribution network , this paper analyzes that the main causes of the accident are ferro-resonance and low frequency nonlinear oscillation .It establishes a simulation model by ATP-EMTP, and makes the simulation analysis on the four main influence factors of TV fuses blowing which are the total length of bus feeder line , TV excitation characteristic , TV primary DC resista…查看全部>>
