As the secondary power supply equipment of the substation,the operation status of the direct current power supply equipment has a great impact on the safe and stable operation of the power grid.Once the direct power loss fault occurs,it will lead to a large area of power failure accident,and the consequences are unimaginable.Based on this,the paper scientifically designs the intelligent monitoring system of direct current power supply,clarifies the hardware structure and main functions,and expounds the realization technology of the monitoring system function.According to the results,through the application of remote charge and discharge monitoring technology,switching power supply monitoring technology and battery voltage balancing technology,the advantages of intelligent power supply monitoring system can be promoted to give full play to,and provide technical support for the realization of online monitoring,diagnosis and analysis of power supply equipment information.
