Abstract:
In order to analyze regional power grid harmonie pollution situation ,a method of fuzzy similarity se-eetion and proximily on grid power harmonie comprehensive evaluation was proposed. Firslly, the index se.quenees between the evaluation objeet and the known objeet were compared and analyzed. Then the proximitindieators were used to evaluate the results, which were combined with fuzzy nearness and grey relational analysis, and the membership of assessment objeet for the oplimal level and next level was aequired to analyze thepurpose of the harmonie pollution situation. This method is simple and involves less ealeulation. Besides, thesealability of indieators is good. lt is suitable for power quality analysis system to assessment harmonie uniformly , and can achieve intelligent management.
