Design and Application of a Centralized Monitoring System for VRLA Based on Electric Power Telecommunication Network

In this paper, a centralized and networked monitoring system for Valve-Regulated Lead-Acid Batteries (VRLA) based on electric power telecommunication network is introduced, detailed structure and software design are presented as well. The system transfers data and commands via the electric power telecommunication network, it is able to perform many critical functions for VRLA such as real-time monitoring, intellectual diagnosis, capacity evaluation, automatic SMS alerts on faults, remote maintenance operations and so on. The system has been installed in some power supply corporations in the country and works fine.
