摘要(Abstract)：

在电力系统中,必须定期对厂站直流系统后备电源—阀控式密封铅酸蓄电池进行核对性放电试验,准确掌握其容量,并保持其活性。为了提高核对性放电试验的准确性,改善放电环境,同时达到节能的目的,结合电力电子技术、信号检测与处理技术、控制技术与理论,对一种基于Boost升压斩波电路的蓄电池有源逆变放电系统进行了研究,既能实现蓄电池恒流放电,核定其容量,又能将蓄电池放出的电能回馈电网,减少能量浪费,改善放电环境。
In power system, discharge test on the backup power source-VRLA(valve regulated lead-acid battery) of DC system in power plants and substations must be regularly conducted to learn its capacity accurately and keep its activity. For the sake of test accuracy enhancement, discharge environment improvement and energy conservation, the paper investigates an active power inverter discharge system of battery based on Boost chopping circuit, which not only enables constant current discharge for capacity check but reduces energy waste by injecting the discharged battery energy into power grid and improves the discharge environment.
