模糊聚类方法在发电机分群中的应用

For multi-machine equivalent in transient stability analysis, the grouping of the disturbed generators is the most important issue that needs to be resolved. This paper researches the clustering strategy for the disturbede generators by the fuzzy clustering method, analyzes the key parameters of this method and introduces the statistics ratio F to ensure the flexible clustering number of distrubed generators. The standard New England 10-genetor power system is used to test the effects of the relevant method, the voting clustering method and the fuzzy clustering method. The test results illustrate that the fuzzy clustering method is very effective and credible in clustering disturbed generators for transient stability analysis in power system.
