Method for monitoring safety and stability of electric network based on stable rule information model

Abstract

The invention relates to a method for safe and stable operation and management of an electric system, in particular to a method for monitoring safety and stability of an electric network based on a stable monitoring rule information model. The method has the following advantages: 1) the unified management of a stable and regular spanning safety area is realized, the consistency and integrality ofthe stable information in different safety areas of electric network operation are ensured,, and the safety hole existing in the stable running of the electric network is eliminated; 2) an electric network schedule automation system can automatically select a stable control surface and a corresponding stable limitation to carry out monitoring in real time, and the potential risks brought to the operation of the electric network by the factors of incomplete, non-unified and untimely manual maintenance on the section and the limitation in the current electric network schedule automation system are eliminated.

Description

technical field [0001] The invention relates to a method for safe and stable operation and management of a power system, in particular to a method for monitoring the safety and stability of a power grid based on a stability monitoring rule information model. Background technique [0002] The power system operation must ensure the safety and stability of the power system. The safety of the power system refers to the ability of the power system to withstand fault disturbances during operation (such as the sudden loss of components of the power system, or short-circuit faults, etc.). It is characterized by two characteristics: (1) The power system can withstand the transient process caused by the fault disturbance and transition to an acceptable operating condition; (2) Under the new operating condition, various constraints are satisfied. Power system stability refers to the ability of the power system to maintain stable operation after being disturbed by accidents. Usually, ...

Problems solved by technology

An object of the present invention is to provide an information model for structurally describing stability rules, so as to achieve a unified formal description of stability monitoring rules across security zones in the dispatch management system and power grid dispatch automation system, as well as the current method and future In this way, the stability rules are managed in a unified manner to ensure the consistency and integrity of the stability information in different security zones of the power grid, eliminate the security loopholes in the stable operation of the power grid, and solve the problem that the stability monitoring rules cannot be managed uniformly across security zones
