The Applications And Research Of Valve Regulated Lead Acid Battery Online Monitoring Technology

Standby power substation widely used VRLA batteries(Valve Regulated Lead Acid Battery) has been widely recognized in terms of performance, its role in the loss of power to the AC power station circuit breakers and other important equipment provided min power-off operation. Reliability relation to the security and stability of the battery, but there are a variety of adverse conditions caused by lower performance on operation and maintenance, shortened life expectancy. Therefore, the current operation and maintenance optimization methods, an accurate grasp of battery backup power performance state is crucial to improve reliability.Background papers for the site in Dongguan, batteries, using analytical theory, the method described in studies conducted internal resistance of the battery, the remaining capacity and aging research coefficient line monitoring technology and designed for grid monitoring system in Dongguan. Firstly, it introduces the remaining battery power, defined aging factor, when used in the current security basis check the discharge capacity measured on law amendments accurate method Peukert equation. It describes the correlation and resistance monitoring advantages and limitations of resistance and remaining power, the aging factor. Study of Two For substation of resistance testing technology: DC discharge, AC discharge method.Next internal mechanism and external factors accelerated aging batteries thesis, found two key points in Dongguan Network affect battery life in operation and maintenance: Operating ambient temperature, the float voltage, and identify five key characteristics of on-line monitoring system should be monitored the amount. Chapter 4 describes the on-line monitoring system for five feature amounts of test module design, system solutions network TCP / IP protocol. Finally, the application of several sets of online monitoring devices Dongguan grid service running, highlighting real-time monitoring system, historical data query, condition evaluation, charge and discharge monitoring and several functional modules, remote centralized monitoring and management of the battery pack.According to the operation and maintenance of existing paper backward status quo, we targeted the battery parametric test systems and networked computer monitoring system combined R & D Battery-line monitoring system greatly reduces battery maintenance costs and improve battery performance and reliability, the effect is significant.
