Abstract

The invention relates to a power grid main equipment blackout window period determination method and system, and the method is characterized in that the method comprises the steps: 1, determining theclassification type of function classification of power transmission and transformation equipment in a power grid according to the functions of the power transmission and transformation equipment; 2,collecting basic data corresponding to the classification type according to the classification type; 3, determining a power-off window period of the power transmission and transformation equipment according to the basic data; 4, outputting and displaying the power-off window period. According to the invention, the corresponding basic data is collected according to the classification type of the function classification of the power transmission and transformation equipment in the power grid, the power-off window period of the power transmission and transformation equipment is determined, outputand displayed according to the basic data, the determination method is scientific and reasonable, the equipment accompanying stop can be reduced, and the potential safety hazard of the power grid caused by maintenance is reduced.

Description

technical field [0001] The invention belongs to the field of electric power system and automation thereof, and in particular relates to a method and system for determining a power outage window period of main equipment of a power grid. Background technique [0002] With the rapid development of the UHV power grid and the large-scale and high proportion of new energy connected to the grid, the grid structure is becoming more and more complex, and it is becoming more and more difficult to arrange power outages for equipment. Power outage planning not only involves power grid security and power balance, but also affects the smooth implementation of UHV construction, municipal relocation, railway construction, and the realization of the national clean energy consumption strategy. The complexity of the power grid and the importance of equipment outages determine that the arrangement of outage plans must be coordinated, scientific and reasonable, and the mode of planning outage pl...
