摘要
目前我国 2 2 0kV线路主保护常采用高频载波保护 ,在新建、扩建及保护更改工程中必然会涉及到线路两侧不同型号、不同原理的高频保护能否配合工作的问题。本文从保护的工作原理及动作逻辑 ,对WXH 80 2微机保护和CSL 1 0 1微机保护配合工作的问题进行了详细地分析 ,并进行了相关的动模试验 ,结果表明WXH 80 2与CSL 1 0
Main protections of 220 kV line often adopt carrier protection in China. In reconstraction and expanding enginecring projects, the problem that whether different protections ofdifferenttypes and priciples on toth line terminals can cooperateor not must be solved. Baing on work principle and operating logic, the cooperation between CSL101 protection and WXH_802 protection was analysed in detail and dynamic simulation test was carried out. Results show that WXh_802 protection can cooperate well with CSL101 protection.
