Substation retired storage battery detection and gradient utilization method

Abstract

The invention relates to a substation retired storage battery detection and gradient utilization method. The method comprises the steps: repairing a returned storage battery of a transformer substation as much as possible through various feasible methods; and then enabling the repaired battery to be connected to a monitoring platform and a remote operation platform, the charging platform is controlled to charge the storage battery and supply power to the power utilization terminal through scheduling of the remote operation platform; during the period, the monitoring platform monitors the stateof the storage battery in real time and can give an alarm for abnormal conditions, so maintenance and management of management personnel are facilitated. According to the method, repair and reutilization of the returned storage battery of the transformer substation are achieved to the maximum extent, the recycling application range and utilization rate of the returned storage battery are expanded, informationized and intelligent management of the storage battery is achieved, and good economic and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of storage battery recycling, in particular to a detection and cascade utilization method of decommissioned storage batteries in substations. Background technique [0002] The battery is the heart of the entire secondary system of the substation. When the AC power fails, the battery becomes the key power for the normal operation of the secondary system such as lighting, control, and signal of the entire substation. Because the battery has the advantages of high safety, low cost, and mature production technology, the substation will still use 110V and 220V lead-acid battery packs as backup power for power dispatching and control for a long time in the future. [0003] Batteries have a service life. The design life of lead-acid batteries is generally 10-12 years, but the capacity of lead-acid batteries equipped in most substations has been lower than 80% of the nominal capacity after 3-5 years of actual operat...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that the existing substation decommissioned batteries cannot be fully utilized, and provide a corresponding detection and cascade utilization method. The method includes the following steps: (a) selecting out substation decommissioned batteries with good appearance, It is repaired by at least one of supplementary additives, full charge and discharge, high current charging, pulse application, etc., and the repaired battery is ready for use after passing the test; (b) connect the repaired battery to the monitoring platform, remote The sensors on the operation platform, charging platform, power consumption terminal, and monitoring platform are responsible for collecting battery parameter information and providing it to the remote operation platform for decision-making; the instructions issued by the remote operation platform are sent to the battery and charging platform to control the battery to supply power to the power consumption terminal respectively. and charge the battery
