Abstract

The invention relates to a multi-fault coordinated static security comprehensive aid decision making method. The method includes the following steps that: the calculation result of static security analysis is read; sensitivity analysis is performed on threshold-crossing devices and failure devices; the adjustment directions of adjustable devices, which are required by the threshold-crossing devices, are determined according to the sensitivity relationship between the threshold-crossing devices and the adjustable devices; if a plurality of devices cross thresholds, whether the adjustment directions of the adjustable devices for the threshold-crossing devices conflict with each other is judged; if the adjustable devices for the threshold-crossing devices do not conflict with each other, the method enters the next step; if the adjustment directions of the adjustable devices for the threshold-crossing devices conflict with each other, an adjustability adequacy indicator is calculated, the adjustment directions of adjustable devices which conflict with each other are determined according to the adjustability adequacy; and multi-fault coordinated static security comprehensive aid decision making is solved. The method provided by the technical schemes of the invention is easy to implement, and a coordination optimization problem which appears when the adjustment requirements of multi-fault static security threshold crossing for the adjustable devices conflict with each other can be solved, and a comprehensive aid decision-making adjustment strategy can be automatically given.

Description

technical field [0001] The invention relates to an auxiliary decision-making method, in particular to a multi-fault coordinated static safety comprehensive auxiliary decision-making method. Background technique [0002] Grid security is related to national security. The security and stability control of the large power grid is an important guarantee for the safe and stable operation of the power grid. With the rapid development of my country's regional power grid interconnection and the steady advancement of UHV power grid construction, the technical level and complexity of power grid operation are getting higher and higher, and the difficulty of power grid operation control is becoming more and more difficult. In this context, it is urgent to fully grasp the operation rules of such a large power grid, develop advanced safety and stability control technology for large power grids, and improve the ability to control the safe and stable economic operation of large power grids...
