This thesis built the models computing the working frequency over - voltage " operation over - voltage for 220kv fugai transmission line, calculates and analyzes working frequency over - voltage " operation over - voltage using emtp program and provides reasonable protection measures for the transmission line. furthermore, regulations method, traveling wave method and striking distance method are used to study and compare lightning - enduring capabilities of different types of pole in power transmission lines aiming at the fact that the lightning strike switching rate of 220kv fugai line is higher
本文分別建立了計算220kv復蓋線路的工頻電壓升高及操作過電壓的計算模型,利用emtp程序對220kv復蓋線路工頻電壓升高、投切空線過電壓、投切空變過電壓、單相故障過電壓進行計算分析,並提出合理的防護措施。 -
Used regulations method calculating, analyzing and comparing the lightning protection performance with field data for the line firstly, . then put forward more reasonable model ( distributing parameter model ) to calculate the surge impedance of tower combining the existing model and validate by emtp, furthermore studied the striking distance factor based on electromagnetism
首先利用規程法對線路的耐雷性能進行計算、分析,並與現場數據比較;同時結合目前對桿塔波阻抗的研究方法,提出一種更合理的桿塔波阻抗計算模型?桿塔分佈參數模型,並利用emtp進行模擬計算和驗證。
