Embodiment 1

[0031] like figure 1 , figure 2 and image 3 As shown: the present invention provides a LAN-based on-line desulphurization and maintenance method for substation batteries, which collects the current, voltage and internal resistance of the battery 7 and feeds them back to the control unit 1. When the voltage has risen to the full value, the battery is charged. If the battery 7 has not recovered its performance, the on-line desulfurization is started. When the battery 7 is cured, the normal charging function is transferred. The control unit 1 will collect the collected data. The performance information of the battery 7 and the sulfur removal information of the battery 7 are sent to the base station 2, and the base station 2 stores it. The information is transmitted to the backend server 3, and the backend server 3 organizes the data, draws graphs and stores the tables. It can realize the information monitoring of the current, voltage and internal resistance of the battery 7,...

Embodiment 2

[0034] like figure 1 , figure 2 and image 3 As shown: the present invention also provides a LAN-based substation battery on-line desulphurization and maintenance system for the above method, including a monitoring unit 5, a control unit 1, a charging desulphurization unit 6, a battery 7, a base station 2, and a background server 3 And the general control center 4, the monitoring unit 5 collects resistance, voltage, and current information on the battery 7, the control unit 1 is connected to the monitoring unit 5 and the charging desulfurization unit 6, and the charging desulfurization unit 6 is connected to the 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-shaped local area network, and the background server 3 is connected to the The above-mentioned master control center 4 is connected. In the present invention, the monitoring unit 5 coll...

Abstract

The invention discloses a LAN-based online desulfurization maintenance method and system for substation storage batteries. The current, voltage, and internal resistance of the storage battery are collected and fed back to a control unit. Send the collected battery information to the base station, and transmit the information received by most of the base stations in the substation to the background server by establishing a star-shaped local area network, and the background server transmits the data to the master control center through the Internet to form a A private Internet of Things for battery performance detection alone. The system includes a monitoring unit, a control unit, a charging desulfurization unit, a battery, a base station, a background server, and a master control center. The present invention establishes a private Internet of Things mode to enable online desulfurization of the battery The system is more intelligent and automatic, and realizes remote online comprehensive monitoring of large-scale unattended substations, which is not affected by time and region, and the data transmission is stable and timely.

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 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 equipment and is in a floating state, over time, the battery will experience abnormal conditions such as shedding of activated materials, drying of electrolyte, plate deformation, plate corrosion and vulcanization, resulting in battery capacity. Reduced or even failed, once the mains 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, many batteries have a lifespan of only 2 to 3 years, and the capacity will decrease significantly af...
