For achieving accurate capacitance prediction of capacitor bank for 10 kV substation

improving the operation life of the capacitor and stability of the power transmission and transformation system

in this paper

a kind of capacitance prediction model of capacitor for 10 kV substation based on AFSA optimized ELM weight and offset is proposed.In this model

the AFSA algorithm is used to optimize input weight and hidden layer offset of ELM so to achieve ELM’s most optimization prediction.It is known through comparison and analysis of such three methods as PSO-ELM

GA-ELM and DE-ELM that capacitance prediction for capacitor of 10 kV substation with AFSA-ELM has the advantages of high prediction accuracy and the method and the method can provide decision base and reference for the capacitance prediction of capacitor bank.
