초록
This paper proposes a new voltage control method of distribution substation using fuzzy inference. The aims of distribution voltage control equipments are reducing the operation frequency of lap changers and improving the characteristics of voltage(decreasing the errors between the actual voltage and the reference voltage). However, these objectives are in a trade-off relationship. Conventional voltage control equipment does not have functions of judgement and prediction, so it turns up limitations of voltage control. Proposed voltage control method using fuzzy inference can improve voltage characteristics as it has those functions of judgement and prediction. This paper describes the design method of new voltage control method using fuzzy inference, simulates with simple voltage and current models, and compares decreased voltage errors with conventional voltage errors.
