| Abstract: | 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. |
