Allocation Strategy Research For Electric Power Emergency Supplies Based On The Regional Importance

At home and abroad in recent years, frequent natural disasters and all kinds of emergencies, the safe and stable operation of the power equipment all kinds of production,life and society has caused great harm. Stable and continuous power supply is to keep the normal human life order and industry one of the important factors to carry out normal production work, even in the event of a disaster are able to carry out the necessary conditions for disaster relief in a timely manner. In the electric power system has a strong continuity,facilities more, wide distribution area, etc. Therefore, when a region suffered widespread natural disasters or external force damage, power system devices tend to appear more suffered severe damage, must pass through power emergency supplies in a timely and reasonable allocate for as soon as possible to restore power by providing powerful guarantee.At this point, you need to have a set of scientific, reliably power emergency rescue plan to carry out the rescue, enables the power supply to recover as soon as possible, for the whole of the disaster relief provide reliable guarantee. In the case of large natural disasters, the deployment of emergency supplies and particularly difficult, a lot of the actual situation of the scene is difficult to grasp, so you need to have a set of reasonable and effective power distribution scheme, as the support power emergency work. Electric power emergency work,cannot in disasters occur and how to carry out comprehensive only through a scientific method, to determine the primary key areas need to recover. Therefore, this article is based on external environment, natural disasters are important grid nodes shortest, material mixing,reasonable allocation to determine the aspects of conducting research.In order to determine the most important need rescue node power system, this article first to the power grid need rescue area of priority for research, the most need of electricity node.In the heart of the research on the basic characteristic of the complex network and the electrical properties of the power supply network to carry out the analysis, the combination of in line number and the maximum transmission capacity of the transmission line as the breakthrough point, the two together, as the power supply network edge weights to solve the condensation degree of node power supply network, resulting in disaster areas most in need of electric power emergency relief supplies.Second in this paper, the electric power emergency supplies transportation path selection problem is studied. Considering fromexternal environment of large natural disasters, roads all kinds of information are unable to obtain timely, accurate, based on the triangular fuzzy number to describe the uncertainty of electric power emergency supplies shipping time, to the optimal path selection of the power emergency supplies transportation research.Is constructed using the time said path weight of triangular fuzzy number’s transport network, and using the concept of security of path, to represent the emergency supplies can meet the demand of disaster relief to the shortest time,finally, using the algorithm of shortest path Canon Dijkstra(Dijkstra) algorithm for emergency supplies allocation theory takes the shortest path and its author. Combining with the disaster area to determine the most important and security of finding the shortest path index of these two aspects, to determine a set of effective, feasible power emergency supplies allocation.Are considered in emergency supplies to areas in the whole power system of important degree, material preparation takes the shortest path and the choice of power emergency supplies total storage capacity and total demand quantity factors, such as comprehensive comparison the emergency supplies power allocation method is established.Finally, the power supply system in jiamusi area as an example, calculates the important degree of the affected area of the grid. Through the deployment of security of the path of the path is calculated, thus obtained path optimization of cargo transport.Through the above analysis, the calculation method can meet the requirements of the emergency time case material allocation, to this article proposed the establishment of emergency supplies power allocation method for actual example analysis.
