Annotation
В данной работе объектом исследования является система собственных нужд ТЭЦ. Цель работы – проектирование релейной защиты и автоматики собственных нужд энергоблока ТЭЦ. Рассчитаны токи короткого замыкания, на основании чего произведен выбор устройств РЗА, получены значения уставок срабатывания и коэффициентов чувствительности. Область применения: непосредственная установка защит и задание ее параметров.
In the given work, the object of study is the system of own needs of combined heat and power plant CHPP. The purpose of the work is the design of relay protection and automation of own needs of the CHPP power unit. The short-circuit currents were calculated, on the basis of which the relay protection devices were selected, the values of the operation settings and sensitivity coefficients were obtained. Scope: direct installation of protection and setting its parameters.
