| Abstract: | Aimed at the shallow discharge test of VRLA battery in substation,key technologies are researched including the prediction of battery remaining power,the evaluation of health state,and the condition of discharge termination and so on.And a shallow discharge battery capacity prediction model is built.Based on the effectiveness and security of shallow discharge,three conditions for discharge termination are proposed.The binomial fitting prediction model is used in this paper to predict the battery capacity by iterative calculation.The result proves that the relative error of the battery capacity prediction is less than 6%by using the method,and the actual discharge time error is within 30 minutes,which is suitable for project application. |
