Abstract
Способ автоматического распределенного отключения нагрузки для целей снижения перетоков активной мощности по элементам энергосистемы при их перегрузке, включающий учет уменьшения ущерба от отключения нагрузки, отличающийся тем, что данный способ может быть использован для отключения нагрузки в сетях со сложной структурой, кроме того, предлагаемый способ использует для своей работы минимальный объем информации и обладает повышенным уровнем отказоустойчивости; предлагаемый способ включает выполнение следующего набора действий: на основании компьютерной модели энергосистемы создают базу данных, содержащую информацию о коэффициентах влияния для каждой линии для различных типов возмущений; на основании разработанной базы данных сложную систему разбивают на совокупность контролируемых и неконтролируемых подсистем, оказывающих минимальное взаимное влияние; все линии и узлы нагрузки в каждой из контролируемых подсистем оснащают агентами связей и агентами нагрузки; внутри каждой контролируемой подсистемы реализуют информационную систему, которая способна организовать передачу сообщений между агентами; агенты связей с определенной периодичностью получают информацию о текущем состоянии узлов нагрузки, которые оказывают наибольшее влияние на загрузку связей, контролируемых агентами; все агенты связей получают соответствующую базу данных коэффициентов чувствительности и предельно допустимых перетоков активной мощности по связям контролируемой подсистемы; далее циклически выполняют следующую совокупность действий: исходя из информации о текущей топологии сети, агенты всех перегруженных связ A method of automatically distributed load shedding for the purpose of reducing active power flows over power system elements during their overload, including accounting for the reduction of damage from load shedding, characterized in that this method can be used to disconnect the load in networks with a complex structure, in addition, the proposed method uses for its work, a minimum amount of information and has a high level of fault tolerance; the proposed method includes the following set of actions: based on a computer model of the power system, a database is created containing information about the influence coefficients for each line for various types of disturbances; based on the developed database, a complex system is divided into a set of controlled and uncontrolled subsystems that have minimal mutual influence; all lines and load nodes in each of the controlled subsystems are equipped with communication agents and load agents; inside each monitored subsystem, they implement an information system that is able to organize the transfer of messages between agents; agents of relations with a certain periodicity receive information about the current state of the load nodes that have the greatest impact on the loading of connections controlled by agents; all communication agents receive the corresponding database of sensitivity coefficients and maximum permissible active power flows through the communications of the controlled subsystem; further cyclically perform the following set of actions: based on information about the current network topology, agents of all overloaded connections
