一种大型水轮发电机组轴电流在线监测分析系统

An On-line Monitoring and Analysis System for Shaft Current of a Large Hydraulic Electric Generator

为进一步提升和保证机组长周期运行的安全性、经济性、稳定性和可靠性,该文设计一种大型水轮发电机组轴电流在线监测分析系统—ATZDL-901轴电流在线监测系统。分析轴电压、轴电流产生的原因,说明轴电流保护的重要性和必要性,详细阐明大型水轮发电机组ATZDL-901轴电流在线监测装置,为同类型水轮发电机组轴电流保护改造提供重要的参考作用。

In order to further improve and ensure the safety,economy,stability,and reliability of long-term operation of the turbine,a large-scale hydraulic generator set shaft current online monitoring and analysis system-ATZDL-901 shaft current online monitoring system is designed.This paper analyzes the causes of shaft voltage and shaft current,explains the importance and necessity of shaft current protection,and expounds in detail the ATZDL-901 shaft current online monitoring device for large hydro generator units,which provides an important reference for the reconstruction of shaft current protection for the same type of hydro generator units.
