Embodiment 1

[0031] like figure 1 , figure 2 and image 3 As shown: the present invention provides a LAN-based on-line desulfurization maintenance method for substation batteries. The current, voltage, and internal resistance of the battery 7 are collected and fed back to the control unit 1. When the internal resistance of the battery 7 increases or the capacity is not fully charged When the voltage has risen to full value, the storage battery is charged. If the storage battery 7 has not recovered its performance, the on-line desulfurization is started. The performance information of the storage battery 7 and the desulfurization information of the storage battery 7 are sent to the base station 2, and the base station 2 stores them, and each substation establishes a background server 3, and then establishes a star-shaped local area network to receive the data from most base stations 2 in the substation The information is transmitted to the background server 3, and the background server 3...

Embodiment 2

[0034] like figure 1 , figure 2 and image 3 As shown: the present invention also provides a LAN-based online desulfurization maintenance system for substation storage batteries for the above method, including a monitoring unit 5, a control unit 1, a charging desulfurization unit 6, a storage battery 7, a base station 2, and a background server 3 and the master control center 4, the monitoring unit 5 collects the resistance, voltage and current information of the storage battery 7, the control unit 1 is connected with the monitoring unit 5 and the charging desulfurization unit 6, and the charging desulfurization unit 6 is connected to the storage battery 7, the control unit 1 is connected to the base station 2 through the RS485 communication interface, the base station 2 is connected to the background server 3 through a star LAN, and the background server 3 is connected to the The master control center 4 is connected. The present invention collects the resistance, voltage,...

Abstract

The invention discloses an online sulphur removal maintaining method and system of storage batteries of an LAN (Local Area Network)-based transformer substation. The online sulphur removal maintaining method comprises the following steps: acquiring currents, voltages and internal resistances of the storage batteries, and feeding the currents, the voltages and the internal resistances back to a control unit; if judging that the storage batteries are vulcanized, starting online sulphur removal, sending acquired information of the storage batteries to the base stations by the control unit, transmitting information received by most of base stations in a transformer substation to a background server by establishing a local area network with a star-shaped structure, and transmitting data to a main control center by the background server by virtue of the Internet to form a private internet of things for solely detecting the performances of the storage batteries. The online sulphur removal maintaining system comprises a monitoring unit, a control unit, a charge sulphur removal unit, storage batteries, base stations, a background server and a main control center. According to the online sulphur removal maintaining method and system, a private internet of things mode is established, so that an online sulphur removal system of the storage batteries is relatively intelligent and automatic, remote online comprehensive monitoring is realized for a large-range unattended transformer substation, no influence by time and a region is achieved, and the data are stably and immediately transmitted.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of substation equipment, in particular to a method and system for on-line desulfurization and maintenance of substation storage batteries based on LAN. Background technique [0002] Lead-acid batteries have been widely used in power systems. Since the battery is usually connected in parallel to the rectifier and is in a floating charge state, over time, the battery will have abnormal conditions such as detachment of activated materials, dry electrolyte, deformation of the plate, corrosion and vulcanization of the plate, which will lead to a decrease in battery capacity. Once the city power is interrupted, it is very likely to cause major accidents such as power supply interruption. Although most manufacturers claim that the design life of their batteries is more than 5 years, in actual use, the life of many batteries is only 2 to 3 years, and the capacity will drop significantly after ...
