Embodiment Construction

[0026] The technical solutions of the present invention will be further elaborated below according to the drawings and in conjunction with the embodiments.

[0027] The present invention constructs a power grid safety and stability control system for power grids with thermal stability problems. The power grid safety and stability control system is composed of two or more power plant safety and stability control devices connected through communication equipment, including a control master station and a control substation. and execution station. The power grid with thermal stability problem refers to the power grid where the line or the main transformer will be overloaded after a fault.

[0028] A method for realizing a thermally stable emergency control system adaptive to the external environment, such as figure 1 shown, including the following steps:

[0029] 1) Classify the components based on the external environment information source of the component operation and determ...

Abstract

The invention discloses an implementation method of a thermally stable emergency control system adaptive to the external environment. Firstly, the relevant fixed value of the external environment state of the component operation is stored; The external environmental state information of the component operation; the method of determining the thermal stability limit value of the component based on the external environmental value ITen of the component, and obtaining the thermal stability limit value of the component through the matching limit value according to the external environmental state information obtained in real time; according to the component Determine the on-duty control strategy table in real time based on the thermal stability limit value; when the power system fails, look up the on-duty control strategy table, implement control measures, and record action information messages. The invention dynamically refreshes the thermal stability limit value of the component used for thermal stability emergency control according to the external environment of the component operation, and solves the technical problem that the actual bearing capacity of the component does not match the external environment during the application process.

Description

technical field [0001] The invention belongs to the technical field of power system thermal stability control, and in particular relates to a method for realizing a thermal stability emergency control system adapting to the external environment. Background technique [0002] Emergency control is the second line of defense to ensure the safe and stable operation of the power grid. After a serious fault occurs in the power grid, the line or the main transformer may be overloaded, that is, the power grid has thermal stability problems. In order to avoid chain accidents and large-scale power outages, emergency control measures should be taken for the existing thermal stability problems. Therefore, the allocation of thermal stability emergency control system is one of the important technical measures to improve the safe and stable operation level of the power grid and improve the power transmission capacity, and it is highly valued by the engineering community. [0003] The ther...
