Problems solved by technology

[0007] With the continuous expansion of the power grid scale, the scale of power clusters is gradually increasing, and the system topology is becoming increasingly complex. The daily operation mode, maintenance operation mode and many transitional operation modes of the power grid need to formulate special security control strategies, resulting in frequent adjustment of security control strategies. Traditional Manual maintenance of safety control policy tables and safety control E files can no longer meet the needs of dispatching and operation. It is urgent to provide automated means to realize adaptive modeling of power system safety control strategies sent by power clusters, and improve power system stability control and online safety and stability analysis. level of automation

Abstract

The invention discloses a self-adaptive modeling method and system for a safety control strategy of a power system sent by a power supply cluster. The method comprises the following steps of S1, carrying out network topology analysis on the power system sent by the power supply cluster, S2, generating a safety control strategy table according to a topology analysis result, and S3, generating a safety control E file according to the topology analysis result and the safety control strategy table. According to the topology structure of an existing power grid, self-adaptive modeling of the power supply cluster safety control strategy can be achieved, complex safety control strategy re-modeling work caused by changes of the topology structure and the operation mode of the power grid is avoided,and the automation level of stability control and online safety stability analysis of a power system is improved.

Description

technical field [0001] The invention belongs to the field of power system automation, and in particular relates to a power system security control strategy self-adaptive modeling method and system sent by a power cluster, which is applied to power system stability control and online security and stability analysis. Background technique [0002] With the increasingly serious problems of energy shortage, global warming and ecological environment deterioration, it has become a global consensus to seek more low-carbon, clean, safe and economical sustainable green energy. The western region of my country is rich in wind, water, coal and energy resources and has superior geographical conditions. Relying on high-quality resource endowments, after years of large-scale development of wind power, photovoltaic power, thermal power and intensive cascade hydropower, a regional power system with numerous power clusters has been formed in the west, and a national power backbone composed of...
