Method, system and readable storage medium for evaluating load capacity of substation equipment

Abstract

The invention discloses a method, system and readable storage medium for evaluating the load capacity of substation equipment. The method includes: obtaining the circuit breaker's circuit breaker capacity increase load capacity model according to the hot spot temperature and total heat loss of the circuit breaker; The hot point temperature and heat flow of the isolating switch are used to obtain the isolation and capacity-increasing load capacity model of the isolating switch; the current capacity-increasing load capacity model of the current transformer is obtained according to the hot-spot temperature and heat production of the current transformer; The load capacity model, isolation capacity increase load capacity model and current capacity increase load capacity model are decomposed and transformed to obtain the comprehensive evaluation model of the bay capacity increase operation load capacity, and the load capacity of the entire bay equipment is determined according to the bay capacity increase operation load capacity comprehensive evaluation model . The invention can perform real-time tracking and compensation for the uncertain factors in the operation of each substation equipment, ensures the stability and service life of the control system, and meets the practical application requirements.

Description

technical field [0001] The invention relates to the technical field of increasing the capacity of substation intervals, in particular to a method, system and readable storage medium for evaluating the load capacity of substation equipment. Background technique [0002] The power system is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. Its function is to convert the primary energy in nature into electric energy through the power generation device, and then supply the electric energy to various users through power transmission, transformation and distribution. In order to realize this function, the power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, communicate and dispatch the production process of electric energy, so as to ensure that users can obtain safe, economical and high-...

AI Technical Summary

Problems solved by technology

However, most of the existing technology for the transformation of power system grids is an accurate model, and in actual engineering applications, there must be nonlinear factors and uncertain interference to limit the load capacity of substation equipment

If effective methods are not taken to deal with nonlinear factors and uncertain disturbances, the stability and service life of the system will be greatly reduced
