The Application And Research Of AC DC Integrated Power Supply’s Diagnosis And Monitoring

With the development of intelligent substation, as part of its important part of AC DC integrated power supply system security stability brings higher requirements.Based on the study of "the application and research of AC DC integrated power supply’s diagnosis and monitoring " subjects, from the AC DC power integration of history and the development trend, a comprehensive understanding of the AC DC power integration technology and composition.The AC DC power integration aspects of monitoring points were cleaned thoroughly, implementation of the switching power supply, DC circuit breaker, feeder grounding, batteries, AC input, the conversion module, real-time monitoring, and in monitoring based on the design of analysis and processing procedures, procedures to achieve the remote operation of AC and DC integrated power supply comprehensive fault diagnosis.Through practical application in this unit substation, the system of AC DC integrated power supply condition maintenance and remote maintenance function, saving a lot of time, so that the maintenance personnel in the first time to grasp the AC and DC power integration of real time condition, the system safe and stable operation of great significance.
