Abstract

The invention discloses a method and a system for on-line maintenance of a storage battery. By means of the method, various parameters of the storage battery, such as inner resistance, voltage and current values can be monitored in on-line mode, the storage battery can be maintained in on-line balanced mode, and when parameters exceed a preset range, maintenance operations can be carried out in terms of the parameters exceeding the preset range, so that the problem of standard exceeding of the parameters can be solved, and qualified working environment and state of the storage battery can be recovered. By means of the method and the system for on-line maintenance of the storage battery, measures for solving the occurred or discovered storage battery problems can be provided, and the problem of the storage battery can be solved timely.

Description

technical field [0001] The invention relates to the field of electric power systems, and more particularly, to a method and system for on-line maintenance of a storage battery. Background technique [0002] With the progress of society, the degree of informatization and automation is getting higher and higher, and the society is more and more dependent on the power, communication, finance and transportation industries, which makes the society put forward a higher reliability of the power supply system. Require. [0003] In the power system, the DC power system is used as the power supply for the relay protection, automatic devices and control operation circuits, and is the basic guarantee for the correctness of the relay protection and automatic devices. As an important part of the DC power system, the performance of the battery directly affects the overall quality of the DC power system. Therefore, the maintenance of batteries has also received great attention from power ...
