Abstract |
Recently, the radial distribution system is operating as one-way power flow. These are popular because of their simple design and relatively low cost. However, radial systems are sensitive to outages due to single contingencies. Also, reliability of supply is becoming increasingly important. Accordingly, an appearance of the loop distribution system is inevitable and the other countries such as Macau, Florida, Taiwan are actively working on. The reliability of distribution system is estimated with reliability indices. In this paper, comparing with the radial distribution system, we evaluate and analyse the reliability of loop distribution system quantitatively considering directional relay. |
