A Multi-Fault Coordinated Static Safety Comprehensive Auxiliary Decision-Making Method

Abstract

A multi-fault coordinated integrative decision-making assistance method for static security and a storage medium. Said method comprises the steps of: 1) reading a calculation result of a static security analysis; 2) analyzing the sensitivities of an out-of-limit device and a faulty device; 3) determining, according to the relationship of sensitivity between the out-of-limit device and an adjustable device, a regulating direction of the adjustable device required by the out-of-limit device; if there are a plurality of devices that are out-of-limit, determining whether there is a conflict in regulating direction between the adjustable devices of the out-of-limit devices; 4) if there is no conflict in regulating direction between the adjustable devices of the out-of-limit devices, performing step 5); if there is a conflict in regulating direction between the adjustable devices of the out-of-limit devices, calculating an index of regulation allowance, and determining, according to the regulation allowance, the regulating directions of the conflicting adjustable devices; 5) obtaining a multi-fault coordinated integrative decision-making assistance solution for static security.

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] Power 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...
