The Cost

Ground wire is one of the lighning protection instrument used in medium voltage distribution network with the intention to reduce interference due to lightning strikes. On the feeder Serangan the ground wire put 4 – 5 wicket. To know effective gap of ground wire is put on the feeder Serangan then used effectiveness ground wire parameters and total of disorder by lightning strikes directly or indirectly. From the analysis is obtained the effective gap on scenario 4 by 3 – 4 wicket. Choosing scenario 4 is as effective gap because seen by economic aspect, as longest gap point put of ground wire then the cost needed to use material and the installation of ground wire will be cheaper.  DOI: 10.24843/MITE.1501.05

Supply Reliability

Aiming at the problems of low power supply reliability, poor transfer capacity between stations, and low line utilization in the current distribution network, this paper proposes a diamond-shaped distribution network structure with a clear structure. First, we investigated the typical wiring patterns of medium-voltage distribution networks in Tokyo, Japan, Paris, France, and China’s developed cities, and summarized experience and shortcomings. Secondly, combining the typical wiring patterns of distribution networks in China and abroad, construct a diamond-shaped distribution network structure, and study its adaptability, safety and flexibility, power supply reliability, and economy. Finally, take the transformation of the wiring mode of a regional distribution network in a certain city as an example, compare the use of the diamond-shaped distribution network structure in this article with the use of cable double-ring network wiring, cable “double petal” wiring, and Shanghai diamond-type wiring distribution network grid reconstruction The effect verifies the superiority of the diamond-shaped distribution network structure in this paper.
