摘要
文中通过对某地区电网历年继电保护运行情况的统计分析,论证了在目前微机保护可靠性、灵活性大幅提高的情况下,实行常规的定期检修已不适应电网发展的需要,并通过故障实例的剖析,进一步证明了实行继电保护状态检修的必要性,最后对继电保护状态检修工作进行了详细的介绍和总结展望。
The statistical analysis for the rtLrming condition of protection relays over the years in a Power Grid is carried out in this paper. It is demonstrated that the routine preventive maintenance has not adapted to the need of power grid development under the condition of significant improvement on reliability and flexibility of the microcomputer protection. More, with some practical fault example, the necessity of condition based maintenance is proved. Finally, it is introduced the works about condition based maintenance of protection relay.
