Research On Intelligent Discharge Control Device For Storage Batteries In Power Substation

This paper presents a method that chopping wave is done by switch devices which consist of three-level resistance regulating module and intelligence power module IPM,and which realizes constant-current discharge of storage battery.To achieve the intelligence control of the drive protection and the discharge process of IPM,the paper designs circuit formed by IGBT threshold drive pulse PWM signals.IPM fault-blocking protection circuit and microcomputer 80C196.The devices can accurately control the 0~150A discharge current and the discharge time of the storage battery and calculate the releasing power.Wen Haipeng (Relay back-up engineering ) Directed by Prof. Wang Zengping...
