结合上海AREVA电力自动化有限公司发电机保护装置的功能特点,介绍景洪水电厂5×350MW发电机保护的配置MiCOM P系列保护装置,实现主保护、后备保护、异常运行保护和后备保护的全套双重化。介绍了操作回路和非电量保护装置单独配置方案,详细论述了发电机故障主保护配置的特点及保护原理。MiCOM P系列保护装置在景洪水电厂的应用,可以看出双主双后的发电机保护方案将成为大型水轮发电机组微机保护的选型趋势。
Combined with the function and features of the generator protection device of Shanghai AREVA Electric Power Automation Co., Ltd., the MiCOM P series protection device for the protection of 5 × 350MW generator in Jinghong Power Plant is introduced to realize the complete dualization of main protection, back-up protection, abnormal operation protection and back-up protection . Introduced the operation circuit and non-power protection device alone configuration scheme, described in detail the main fault configuration of the generator fault protection features and principles. Application of MiCOM P Series Protection Device in Jinghong Power Plant shows that the generator protection scheme with double main and double rear will become the selection trend of microcomputer protection of large hydrogenerator sets.
