Adaptive Optimization Method for Overcurrent Protection of Weak Feedback Lines in Photovoltaic Access Distribution Network
Due to the long action time of the current feeder,the ideal protection effect cannot be obtained,so an adaptive optimization method of current protection passing by the weak feeder of the photovoltaic access distribution network is designed this time.Firstly,the impedance characteristics of the weak feed line are analyzed,and the correlation impedance matrix of the weak feed line is generated.Then,based on this,the adaptive optimization model of overcurrent protection is constructed.Finally,the adaptive protection is realized by optimizing the current protection method.The results show that the action time is shorter and the application effect is better.
