摘要
近年来由于厂高变保护配置及整定计算不合理造成保护越级跳闸的情况均有发生。文章以鲁地拉水电站的厂高变保护配置过程为例,就大型水电厂的厂高变保护配置及整定计算中的一些问题进行探讨。
In recent years, override trip for protection of the HV service transformer occurs due to the irrational protection device arrangement and calibration calculation.In this paper, the protection arrangement course of the HV service transformer of Ludila Hydropower Project is sampled to explore and study certain issues in protection device arrangement and calibration calculation of the HV service transformers applied in large-sized hydropower plants.
