(54) СИСТ УПРАВЛЕНИЯ ТЕМПЕРАТУРОЙ ПАРА ЗА ПРОМПЕРЕГРЕВАТЕЛЕМ ТЕПЛОВОГО АГРЕГАТА(54) STEAM TEMPERATURE MANAGEMENT SYSTEM FOR THE PROMPER HEATER OF THE HEAT UNIT
tt
Изобретение относитс к теплоэнергетике, в частности к автоматизации тепловых агрегатов с парогазовыми установками, оборудованными промперегревател ми.The invention relates to a power system, in particular to the automation of heat units with combined-cycle plants equipped with reheaters.
Известны системы управлени температурой пара за промперегревателем теплового агрегата , содержащие главный регул тор, регул тор температуры, клапан байпасировани дымовых газов, клапан подачи охлаждающей воды в пароохладитель , клапан дымососа н два датчика температуры до и после теплообменника П.The steam temperature control systems behind the reheat unit of the heating unit are known, which contain a main controller, a temperature controller, a flue gas bypass valve, a cooling water supply valve to the desuperheater, an air exhauster valve and two temperature sensors before and after the heat exchanger P.
Однако известна система не позвол ет достигнуть требуемого качества управлени тем пературой в теплоагрегатах с парогазовыми установками .However, the known system does not allow achieving the required quality of temperature control in heat units with combined-cycle plants.
Цель изобретени - повышение качества управлени температурой в теплоагрегатах с парогазовыми установками.The purpose of the invention is to improve the quality of temperature control in heat units with steam-gas installations.
Поставленна цель достигаетс тем, что устройство дополнительно содержит логический блок, сумматор, дифференциатор, а регул тор температуры выполнен с блоком безударного включени и корректором уставок, причем логический блок установлен между регул торомThe goal is achieved by the fact that the device additionally contains a logic unit, an adder, a differentiator, and the temperature controller is made with an unstressed switching unit and a setpoint corrector, the logic unit being installed between the controller
температуры и клапанами и соединен с главным регул тором и корректором уставок, а на вход регул тора подключен сумматор с первым датчиком температуры, дифференциатор и второй датчик температуры.temperature and valves and is connected to the main regulator and the corrector settings, and the controller input is connected to the adder with the first temperature sensor, a differentiator and a second temperature sensor.
На чертеже представлена схема устройства.The drawing shows a diagram of the device.
