A Research On The Control & Supervision System Of High-frequency Switching Power Supply

Have analyzed that the state of development of the controls device of the communication high-frequency switch power at home and abroad in this text, it has some questions in the control device of the communication high-frequency switch power in the past. And the necessity and possibility of state overhaul are expatiated aiming at the post method of plan overhaul to the communication power supply system. On the basis of existing communication monitoring system, have developed the control & supervision system of high-frequency switching power supply. Have realized the monitor in real time to the YIKE communication high frequency switch power system in ZHUZE 220kv substation. Have grasped the operation conditions of the power supply equipment. This system fully used the existing communication monitoring system to collect the data. By adding and installing the protocol converter, we can get the real-time data. The system is greatly reduced. At the same time, through increase computer software function in the communication control center, make it have function of diagnosis and pre-alarm. This scheme key lies in development of the communication protocol converter and development of the diagnosis and pre-alarm software. It indicates that this system can realize the control & supervision to the switch power in a most direct way. The test result proves that we may achieve the purpose of control & supervision with the investment at least, the simplest device, most reliable performance.
