Multi-fire-point power grid risk matrix add zero transform quick rescue method and system

Abstract

The invention relates to the technical field of electrical engineering and computer processing, and discloses a multi-fire-point power grid risk matrix add zero transform quick rescue method and system. The optimal emergency dispatching strategy of power grid fire extinguishing equipment can be quickly and accurately formulated. Overall optimization of the relative position of fire points and the fire extinguishing equipment and the fire extinguishing equipment path under the situation of multiple fire points is considered, and the problem of emergency rescue optimization is converted into the problem of optimal matching of the fire extinguishing equipment and the mountain fire disaster and the problem is solved through risk matrix add zero transform. Besides, the problem of element selection of the risk matrix before and after add zero transform has the same solution so that add zero transform. Is enabled to meet the scientific requirement, and the theoretical optimal solution of the fire extinguishing equipment emergence rescue path under the mountain fire disaster can be quickly and accurately obtained; then the optimal dispatching strategy of the fire extinguishing equipment can be quickly formulated and the loss of the power grid is enabled to be minimized; and thus the method and the system have an important effect in guiding the fire extinguishing equipment to implement the optimal power gird mountain fire rescue and reducing the loss of the power grid.

Description

technical field [0001] The invention relates to the technical fields of electrical engineering and computer processing, in particular to a rapid rescue method and system for multi-fire point power grid risk matrix multiplication and zero transformation. Background technique [0002] Affected by many factors such as industrial and agricultural fire usage customs and climate, wildfire disasters often break out simultaneously in a large area, causing multiple power grid transmission lines to trip at the same time, seriously threatening the safety of the power grid. [0003] When there is a wildfire near the transmission line of the power grid, fire extinguishing equipment must be arranged immediately to extinguish the fire, so as to reduce the harm of the large-scale wildfire disaster to the power grid. When multiple fire points break out in the power grid at the same time, it is necessary to study the optimal fire extinguishing equipment deployment plan. losses are minimized....

Problems solved by technology

If the enumeration method is used to traverse all the different allocation schemes for optimization, there will be a curse of dimensionality. For example, when there are 50 fire points and 20 fire extinguishing equipment, there are a total of about 1.15×10 32 A possible solution, which does not meet the emergency needs of the actual power grid

[0004] Patent ZL201410191734.2 proposes a fire behavior characteristic analysis method for intelligent emergency response to mountain fires on transmission lines. This method obtains fire point risk indicators by calculating the fire point distance index, analyzing fire behavior characteristics, and calculating vegetation condition index, etc., and According to the different degree of risk of fire point, different disposal measures are adopted, and the optimization of disposal measures is not considered as a whole; the patent CN103942458A proposes an intelligent optimization method for emergency disposal of transmission lines under large-scale mountain fire disasters. This method uses TOPSIS to calculate the fire point Risk ranking, arrange fire extinguishing according to the different risks of fire points, without considering the relative position of fire points and fire extinguishing equipment in the case of multiple fire points, and the overall optimization of the path of fire extinguishing equipment; patent CN104915775A proposes a power transmission under mountain fire disasters Line risk assessment and emergency decision-making method, this method first calculates the risk ranking of all fire points, and then prioritizes the fire points with high risk priority, without considering the maximization of the overall disposal benefit
