Problems solved by technology

[0003] On the other hand, since the "three-remote" terminals generally use optical fiber communication, the laying of optical fibers in overhead networks can be realized by hanging rods, which is relatively low in implementation difficulty and cost, while the laying of optical fibers in cable networks often requires installation without pipes and holes. Excavation and direct burial are used for resources, and the implementation difficulty and cost (including engineering fees and compensation fees) are relatively high, and the cost of optical fiber laying accounts for a very high proportion of the total cost

Abstract

The invention relates to an A+ area 10KV overhead network distribution automation terminal stationing planning method comprising the following steps: 1, determining overhead network classic rack typesand node classifications; 2, setting three-remote nodes according to node classifications; 3, stationing terminals on the three-remote nodes; 4, calculating and checking the power supply reliabilityof the stationing result; 5, optimizing terminal stationing according to the checking results. Compared with the prior art, the method is reasonable and reliable in stationing, and can reduce the fault locating time.

Description

technical field [0001] The invention relates to the field of power distribution of a typical network frame, in particular to a distribution planning method for a power distribution automation terminal of a 10kV overhead network in an A+ area. Background technique [0002] According to the current overall situation, the power supply reliability rate of the overhead network is significantly lower than that of the cable network. Therefore, in terms of reliability requirements, the distribution automation terminal configuration standard of the overhead network should be higher than that of the cable network. [0003] On the other hand, since the "three-remote" terminals generally use optical fiber communication, the laying of optical fibers in overhead networks can be realized by hanging rods, which is relatively low in implementation difficulty and cost, while the laying of optical fibers in cable networks often requires installation without pipes and holes. Excavation and dir...
