Abstract: The doubly-fed induction generator（DFIG）is the mainstream model in the wind power market.Since there are multiple time-scale control objectives in the wind turbine，it is difficult for conventional linearcontrol methods to optimize the multi-objective. Model predictive control（MPC）is an effective method for...

Abstract：Harmonic loss is one of the main causes of safety accidents in excitation transformers. If the lossvalue is too large，it can easily affect normal substation and transmission. Therefore，a method based on waveletpacket decomposition and reconstruction was proposed to calculate the additional loss of rectifica...
