Realization method of thermal stability emergency control system adaptive to external environment

Abstract

The invention discloses a realization method of a thermal stability emergency control system adaptive to external environment. The method comprises the following steps: to begin with, storing relevantstate fixed value of external environment where an element operates; determining an external environment information source of the external environment where the element operates based on the external environment fixed value ITen of the element, and obtaining state information of the external environment where the element operates in real time; determining an element thermal stability limit valueobtaining method based on the external environment value ITen of the element, and obtaining a thermal stability limit value of the element according to the external environment state information obtained in real time and a matched limit fixed value; determining an on-duty control strategy table in real time according to the thermal stability limit value of the element; and when an electrical power system has a fault, searching the on-duty control strategy table, executing a control measure and recording an action information message. The method dynamically refreshes the thermal stability limit value of the element for emergency control of thermal stability according to the external environment where the element operates, and solves the technical problem of mismatch between actual load capacity of the element and the external environment in 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...
