Проблема маневренности энергоблока АЭС и развитие моделей его систем управления

Abstract

Проанализирована проблема маневренности энергоблоков АЭС. Приведена модель энергоблока ВВЭР-1000 для анализа переходных процессов. Переходные процессы изменения состояния энергоблока не противоречат возможности его работы в маневренных режимах. Многозонная модель реактора использована для исследования комбинированного метода управления. Отмечены недостатки методов управления энергоблоком для развития его системы управления.The problem of maneuverability for units of nuclear power plants in Ukraine was analyzed and to solve this problem need to modernize the systems of automatic control units was justified. The linear model for unit of nuclear power plants with reactor WWER-1000 to analyze transients after changing load of the electrical generator were shown. On base of this model the synthesis of optimal automatic control systems in normal operation modes with various regulators was made. Transients of changing state of power unit were shown. According to its temporal characteristics of these processes do not contradict the possibility of work power unit maneuvering modes. For research of the compromise combined method of control that provided stability of the reactor, the multizone model of nuclear reactor with calculation of axial offset in the model of power unit was used. Disadvantages of different models and methods of control by power unit of nuclear power plant in order to improve its control system were analyzed.
