西洱河梯级电站计算机监控系统电源改造

Power Supply Improvement of the Computer Monitoring and Control System of Xierhe Cascade Hydropower Station

电站、变电站计算机监控系统供电电源是否可靠,是系统正常运行的关键。在西洱河梯级4个水电站计算机监控系统电源改造中,选用逆变器更换不间断电源(UPS),以电站直流220 V电源作为后备电源。4套电源系统至今运行稳定可靠,特别是保障了电站事故情况下监控系统的正常运行,有利于事故处理。

Reliability of power supply is the key to normal operation of the computer monitoring and control system of power stations and substations. In power supply improvement of the computer monitoring and control system of the Xierhe Cascade Hydropower Station, UPSs are replaced with serial inverters, and 220 V DC is used as standby power supply. The four power systems have been reliable since they were improved, and especially the normal operation of the computer monitoring and control system in fault status is guaranteed, favorable for the treatment of accidents.
