| With the power grid construction investment continued to increase in Dongying region, to further improve its network structure, the degree of complexity of the grid increasingly high reliability of the power supply requirements are also gradually increase. As we all know, is different from the transmission and distribution equipment substation equipment, most of the equipment is located on the outskirts of the wilderness, with the regional power grid Dongying special geographical and environmental conditions, such that the probability of transmission and distribution equipment failure is generally greater than the substation equipment, thus increasing output power distribution equipment reliability is critical. This article will focus on research in Dongying grid reliability upgrade transmission and distribution of power. Dongying currently affecting power lines supply reliability factors include external damage, bird damage, dancing, partial lack of wind, lightning and so on. Combined with the actual situation in Dongying regional power grid, external damage is caused by brake line out the most important factor, and in recent years due to external damage caused by the line forced outage frequent occurrence, in addition to bird damage and dancing as an important influence reliability of power transmission equipment factors have a greater impact on the operation of the power grid in Dongying, it is currently an urgent problem..To solve these problems, this paper summarizes the operation of transmission and distribution lines in recent years, Dongying grid data, and through charts, and other means of multi-dimensional data mining analysis; system on the impact of transmission and distribution lines safe and stable operation of the Dongying area several factors, combined with more than transmission and distribution lines tripping accidents have occurred in recent years, Dongying grid by sampling and analysis and investigation of the reasons to develop a number of specific measures to improve the governance principles and, at the same time introduce these measures made effect results. To enhance the reliability of power supply distribution network level, the paper further analyzes the distribution automation principle and mode of operation, combined with practical cases Dongying grid describes the construction of distribution automation. |
