Embodiment

[0053] A kind of power grid intelligent self-healing method after typhoon disaster of this embodiment, such as figure 1 shown, including the following steps:

[0054] S1: Real-time monitoring of post-disaster power grid data at all levels, the power grids at all levels transmit the data to the data processing center, and the data processing center collects statistics on the disaster situation of the power grid at all levels.

[0055] S11: By installing monitoring equipment in the city-level power grid, county-level power grid and grid-level power grid, real-time monitoring of the data of each power grid after the typhoon disaster, and transmitting the power grid data to the data processing center.

[0056] Grid data includes generator power angle, bus voltage phase angle, and line active, reactive, voltage, and frequency. If the monitoring equipment cannot monitor the corresponding power grid operating condition parameters, the transmission data will be 0, which means a serio...

Abstract

The invention discloses a power grid intelligent self-healing method after a typhoon disaster. The problems that the power grid self-healing control method in the prior art is simple in model and difficult to reflect the dynamic adjustment process of a power grid are solved. The method comprises the following steps: S1, monitoring data of each level of power grid after a disaster in real time, and collecting and counting disaster conditions of each level of power grid; S2, establishing a three-dimensional energy distribution model according to the data of each level of power grid; S3, according to the three-dimensional energy distribution model, in combination with disaster condition analysis of each level of power grid, making a source-grid-load-storage collaborative self-healing plan for each power grid in a disaster area, and limiting the execution recovery time of each healing plan; S4, after the execution recovery time of the self-healing plan is ended, judging whether the self-healing of the power grid is completed or not; and if the self-healing is not completed, updating the disaster condition of the power grid, and returning to the step S3 to reformulate the self-healing plan. According to the invention, through a source-grid-load-storage cooperative control technical means, the power grids at all levels are dynamically adjusted, the feedback is real-time and real, and the self-healing efficiency is improved.

Description

technical field [0001] The invention relates to the field of a power grid self-healing method, in particular to an intelligent self-healing method for a power grid after a typhoon disaster. Background technique [0002] Typhoons are one of the weather factors that have the greatest impact on power transmission networks. The coastal cities in southeastern my country are hit by typhoons every year, and each typhoon will cause considerable damage to the local power grid. The healthy operation of the power grid is related to the local production and living standards. Therefore, there is a certain demand for the self-healing technology of the power grid after the typhoon disaster. [0003] At present, there are some self-healing control methods for power grids. For example, a "self-healing control method for urban distribution network" disclosed in Chinese patent documents, its announcement number CN101436780B, includes the following steps: (1) define a Current, active power, r...
