龙溪一级水电站机电一体化技术改造分析

摘要

Control and relay protection devices are adopted in Longxi level 1 hydropower station,which mostly belong to conventional relay control systems.They are characterized by high failure rate,poor reliability,low level of automation and inconvenient operation and maintenance.The electric station automation level is improved,and hidden danger is eliminated on one hand through technical reform ation,operator labor intensity is lowered,and operation management mode of‘less persons in duty’is realized on the other hand.%龙溪一级水电站原采用的控制及继电保护装置，大多为常规继电器控制设备，故障率高、可靠性差，而且自动化水平低、操作维护极不方便。通过技术改造不但提高了电站自动化水平、消除了设备安全隐患，而且降低了运行人员劳动强度，实现了“少人值守”运行管理模式。
