Supply Reliability

It is difficult to evaluate and analyze power supply reliability of large-scale medium voltage distribution network by detailed modeling method. The paper proposes a power supply reliability evaluation method of large-scale medium voltage distribution network, which is based on the network reliability characteristics model. Lines with similar structural characteristics are designated as one model. The reliability index of each mode can be represented by the typical lines. The assessment principle, process and the advantages of this method are elaborated. The medium voltage distribution network of Nanjing area is taken as an example to evaluate power supply reliability. And the results are compared with historical statistics. The result shows that the method can greatly reduce the workload and has high accuracy. It can be used to evaluate the reliability of large-scale medium voltage distribution network.

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
