Study On The Active-Power Inverter Discharge And The Analysis Of The Battery's Character

This paper mostly research the method which detects and analyses the character of the valve regulated lead-acid battery(VRAL) using in the transformer substation. The paper presents a method and standard, which estimates the character by on-line monitor the change of the floating voltage and the discharge voltage. The farther improve on the microprocessor phase-controlled rectification charger is carried, the function of the inverter discharge is increased, the safeguard of prevent discharge failed is brought, the discharge under the invariable current is realized. It'll decrease the labour intensity. The SMCDâ…¡direct current system auto-monitor device is developed, and the basic function of the direct current system on-line monitor is improved. The software of the battery's character auto- analyse is finished, it can analyse the important parameter in the testing course, finds the invalidation battery and analyse the characters of battery automatically.Xia HongGang (Electrical engineering) Directed by Prof. Yan Xiangwu...
