摘要
微机继电保护装置以其性能优、可靠性高、功能齐全、灵活性强、调试维护方便等优势越来越受到用户的青睐,电动机差动保护作为功率大于2000 kW的高压电机主保护,在电力系统中得到了广泛的应用。总结了某数字式电动机差动保护装置性能测试的一些经验,提出性能测试的方法以及常见问题的解决方法。
Microprocessor - based relay protection device has obtained the more and more favour of the users because of its good performance, high reliability, complete function, strong flexibility and convenient debugging and maintenance. Differential protection device of motor as the prime protection device of the high- voltage motor with power rating above 2000 kW are applied widely in the electric power system. This paper introduces the experience gained in the performance test of the differential protection device of a digital motor, also expounds the test steps and the solution methods for some common problems.
