Comparison and analysis of grouping and aggregation algorithm for induction motor group
Induction motor equivalent is one of the most important parts in load modeling with strong influence on the accuracy of power system simulation calculation.Due to the great difference in the load characteristics of each motor,it's difficult to determine the principle which the grouping and aggregation algorithm based on.In this paper,the three typical grouping algorithms and three aggregation algorithms were cross-combined to equivalent the 7 typical induction motors recommended by IEEE,and the equivalent effect of each method was compared in single machine infinite system to study the influence on the equivalence accuracy of each method.The results show that there is a significant difference in the equivalence effect of different equivalence methods after the cross-combination of the three grouping algorithms and the three aggregation algorithms,among which the weighted aggregation method based on the correction of motor load factor and critical slip has the best equivalence effect.
