On the basis of traditional data envelopment analysis model, by introducing the ideal decision making unit, the improved data envelopment analysis model is established to determine a set of common weights; then according to them , efficiency index of each black start plan is calculated to rank the black start plans. Finally, it is verified that this method is effective and advantageous through the...
According to the BP neural network fault line when the input data amount is large, its structure is complex, convergence slowly, and easy to fall into the local optimal shortcomings, we will put fuzzy rough sets and the genetic algorithm to optimize the method of neural network into one-phase ground fault distribution network in line. We obtained the line of zero sequence current signals through the...
