Abstract:

Auxiliary power supply system of a substation is important to the station's safe and reliable operation.The system is mainly composed of AC power supply system,DC power supply system and AC uninterruptible power supply system.To effectively evaluate the operation states of AC and DC power supply systems,an online state assessment system for substation auxiliary power supply system is proposed which works with the collaboration of the main system and the subsystem.After introducing the main functions and components of the main and sub-systems,the assessing process and the criteria for assessing the AC power supply equipment,inverter power equipment,DC/DC communication power supply equipment and DC power supply equipment are expounded.According to its application situation in a substation,the assessment system is proven to be effective in keep the safe and reliable operation of auxiliary power supply system in substation.It is of engineering application value.

Key words: substation, power supply system, online state assessment, AC power supply equipment, inverter power supply equipment, DC/DC communication power supply equipment, DC power supply equipment
