Повышение надежности функционирования объектов энергетики, управляемых оператором

Повышение надежности функционирования объектов энергетики, управляемых оператором

Abstract

При управлении объектами энергетики в работе операторов возникают сложные ситуации неопределенности в показаниях приборов и измерителей, противоречия в показаниях, выход индицируемых показаний за пределы допустимых значений. Цель статьи заключается в повышении надежности функционирования автоматизированных объектов энергетики, за счёт применения информационной системы поддержки операторской деятельности, сущность которой заключается в формировании моделей изменения фазовых координат и управляющих воздействий объектом, применяемых в системе информационной поддержки. При возникновении неопределенностей в течение сеанса управления объектом предлагается использовать эвристические способности оператора для коррекции определенной части базы данных, а именно базы моделей в случаях, когда оператору удается быстро найти приемлемый для практики способ разрешения возникшей неопределенности. Разработанный подход снижает психическую нагрузку оператора, повышает его помехоустойчивость и пропускную способность при возникновении неблагоприятных психологических факторов. Показана целесообразность оперативной коррекции базы данных информационной системы поддержки принятия решений.

When controlling power objects operators face difficult situations of uncertainty and contradictions in instrument readings, release of displayed indications out of admissible value limit. The purpose of the paper consists in increasing reliability of automated power objects functioning applying the information system of operator activity support. The authors have developed the approach to operator activity information support in uncertainty. The matter of the approach consists in forming the models of changing phase coordinates and the control action by the object applied in the information support system. When indefiniteness occur during the object control the operator heuristic abilities are offered to be used to correct a certain part of a database, the model bases in cases when the operator manages to find quickly the way to solve the uncertainty accepted for practice. The approach developed reduces the operator mental load, increases his noise stability and capacity at occurrence of adverse psychological factors. The paper introduces the appropriateness of on-line correction of a database of information decision-support system.
