摘要
以 50 0kV深圳站为例 ,阐述了 80年代中期我国引进的ABB继电保护装置的原理及运行情况 ,并从原理、性能、运行、维护、试验等角度与国产继电保护进行分析比较。文章在肯定ABB继电保护总体工艺水平较好的同时 ,也指出了ABB继电保护在运行、试验中存在的不少问题。侧重于在运行、试验中国内外继电保护存在问题的分析比较 ,抛砖引玉以期得到同行专家们的认同及关注 ,更进一步完善和改进继电保护 。
With 500 kV Shenzhen substation as an example, the principles and operational conditions of ABB protections are introduced. These protections are imported in the middle of 1980s. They are analyzed and compared with the domestic protections in respect of principle, performance, operation, maintenance and test. Though the general technology level is higher, there are some problems found in the operation and test of ABB protections. The analysis and comparison of the existiong problems in operation and test between the imported and domestic protections are emphasized, as to attract more attention of the experts to solve the problems and improve the protection function.
