Abstract

The invention discloses an automatic capacity nuclear method and device for a DC system of a substation, wherein the automatic capacity nuclear method includes: a processor module controls the conduction of the first switch module to discharge the storage battery at a constant current; The capacity of the battery is obtained by the voltage variation and the discharge time of the battery; the processor module controls the first switch module to be turned off, and controls the second switch module to be turned on, so that the rectifier in the DC system charges the battery with a constant current. The invention solves the technical problem of low efficiency of operation and maintenance of the DC system of the substation and the storage battery due to the industry status quo in which the periodic checking discharge of the battery pack of the DC system of the substation must be operated by professionals on the spot.

Description

technical field [0001] The invention relates to the field of automation control, in particular to an automatic nuclear capacity method and device for a DC system of a substation. Background technique [0002] The DC system of the substation is an important part of the substation. The battery pack in the DC system of the substation can provide safe, stable and reliable power guarantee for the secondary system load in the power system, and ensure the normal operation of the control, protection and communication equipment of the substation. The stability of the battery pack and the actual capacity that can be provided to the load during the discharge process are of great significance to ensure the safe operation of power equipment. [0003] The battery packs in the existing DC system of the substation are connected to the rectifier and the load through the DC system bus, and the control switch is used to switch the line to complete the process of discharging and recharging the ...
