摘要
介绍了RCS-985R/S微机发电机保护在抽水蓄能机组上的成功应用。描述了岗南抽水蓄能机组的概况,详细阐述了机组特点及其保护配置方案,分析了换相和倒极操作对保护的影响、3种不同运行工况对保护的要求以及如何判别抽水蓄能机组的运行工况;对微机改造后岗南1号机组保护的运行情况进行了简要分析。最后,指出为确保抽水蓄能机组保护正确、可靠运行,必须合理处理好的几个关键技术环节。
The successful application of RCS - 985R / S microcomputer-based generator protection in pumped storage generator set is introduced. The conditions of pumped storage generator set in Gangnan power plant are surveyed,and its features and protection configuration scheme are expounded in detail. The effect of phase change and pole change on protection,the requirements in different operation states and the way to detect generator working condition are illustrated. The operating condition of reconstructed protection of generator #1 is analyzed briefly. Several key techniques are pointed out to ensure the protection working correctly and reliably.
