Aggregation of Induction Motor Group Considering Physical Characteristics and Static Critical Stable Characteristics
摘要
Abstract
Induction motor aggregation isone of the most important parts in load modeling with strong influence on power system stability analysis. Considering influence of induction motor's static critical stable characteristics, a new aggregation algorithm of induction motor group was proposed. Firstly, induction motor group was divided into two groups according to their indexes representing static critical stability. Secondly, the divided induction motor groups were aggregated based on their physical mechanism while considering static critical stable characteristics. Finally, taking single machine infinite systems, WSCC-9 bus system and EPRI-36 bus system as examples, system response in different fault states was investigated using the proposed aggregation algorithm and other methods. Applicability of the proposed algorithm under different operating conditions and accuracy of the equivalent model were validated by test results.关键词
