雙端同步故障定位演算法於Matlab/Simulink模擬案例探討
Discussion for Synchronized Two Terminals Fault Location Algorithm with Matlab/Simulink Cases
摘要
電力系統包含發電、輸電及配電三大部分，輸電是發電與配電之間的線路。隨著國家的工商業發展愈來愈發達，市區的範圍逐漸擴大，對電力的需求也不斷地增加，滿足人們的電力需求以及提供穩定的電力是電力公司最大的目標。在市區裡的輸配電線路，早期都是採用架空線路，傳統的架空線路大部分都直接暴露在室外，比較容易受到天然災害或是人為因素的破壞。因此，都市的電纜線逐漸從傳統的架空式改為地下化。目前常用的故障定位方法有電橋法、低壓脈衝反射法、脈衝電壓法、脈衝電流法…等等，各種方法均有其優缺點以及適用的故障情況與電力系統配置。本論文使用雙端同步故障定位演算法，並搭配Matlab/Simulink模擬各種故障情況，驗證其高度精準的故障定位能力，讓維修人員可以快速進行維修，減少電力中斷期間造成的損失。

The power system includes electricity generation, electricity transmission and electricity distribution. With the development of the industry and commerce in Taiwan, the urban areas and the demand of electricity grow rapidly. Providing sufficient and stable electricity is the priority goal of the power company. Because of the limits of overhead transmission lines, underground cable became the major transmission equipment in Taiwan. Many fault location methods are used nowadays, and every method has its own advantage and suitable fault condition. In this paper, we use synchronized two terminals fault location algorithm. And verify it on Matlab/Simulink. By this fault location system, maintenance personnel can perform maintenance or repair quickly. Reducing the economic lost during power interruption.
