| Abstract |
When a fault occurs in the distribution feeder, the distribution system operator recognizes the state of the system and makes a restoration plan to deal with the fault based on alarms delivered to the ADMS(Advanced Distribution Management System). It is difficult to rapidly determine the system operating condition because numerous alarms due to the fault are generated at the same time. This paper presents a method to detect a fault on the distribution feeder considering the situation where a lot of alarms are delivered to the ADMS. The proposed method supports distribution system operators to intuitively determine the situation by analyzing and filtering the characteristics of field alarms. By processing alarms sequentially and designing different processing algorithms according to their characteristics, faults can be rapidly determined. To verify the feasibility of the proposed fault diagnosis method, case studies have been performed in various fault conditions. |
