Изобретение относитс к теплоэнергетике и может быть использовано дл автоматического регулировани теплофикационных турбоагрегатов.The invention relates to a power system and can be used to automatically regulate heat-generating turbine units.
Наиболее близка ,к изобретению система регулировани теплофикационного турбоагрегата , содержаща регул тор расхода свежего пара, снабженный задатчиком и датчиком расхода свежего пара, и св занный с датчиком давлени пара в теплофикационном отборе, и блок управлени клапанами турбоагрегата, подключенный к выходу регул тора расхода свежего пара 1.Closest to the invention is the control system for a heat-generating turbine unit, containing a fresh steam flow regulator, equipped with a setpoint sensor and a fresh steam flow sensor, and connected to a steam pressure sensor in a heat extraction pump, and a control unit for the turbine unit connected to the fresh steam flow regulator one.
Недостатком известной системы вл етс пониженна надежность из-за неполного учета возможности снижени максимально допустимого расхода свежего пара.A disadvantage of the known system is reduced reliability due to incomplete consideration of the possibility of reducing the maximum allowable consumption of fresh steam.
Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.
Указанна цель достигаетс тем, что в систему введен корректирующий регул тор, снабженный блоком импульсного интегрировани , и датчик давлени пара в отборе св зан с регул тором расхода через этот корректирующий регул тор.This goal is achieved by introducing a correction regulator fitted with a pulse integration unit into the system, and the vapor pressure sensor in the selection is connected to the flow regulator through this corrective regulator.
На чертеже представлена схема системы регулировани .The drawing shows a diagram of the regulation system.
Теплофикационный турбоагрегат имеет части 1-3 высокого давлени и соединен с конденсатором 4, генератором 5 и магистралью 6 теплофикационного отбора пара на сетевой подогреватель 7, последователь5 но с которым включают пиковый водогрейный котел 8 подогрева сетевой воды. Исполнительный механизм 9 hapoBnycKa и регулирующий орган 10 теплофикационного отбора предназначены дл изменени расхода па ,Q pa в часть 1 турбоагрегата и в магистраль 6 отбора пара по сигналам блока 11 управлени клапанами турбоагрегата.The heat-generating turbine unit has high-pressure parts 1-3 and is connected to a condenser 4, a generator 5, and a main line 6 of the steam extraction steam to a network heater 7, which, however, includes a peak hot-water boiler 8 for heating the network water. The hapoBnycKa actuator 9 and the heat extraction selection regulator 10 are designed to change the flow rate of the pa, Q pa to the turbine unit part 1 and to the steam extraction line 6 according to the signals from the turbine unit control unit 11.
На вход блока 11 подсоединен регул тор 12 расхода свежего пара на турбоагрегат, 15 к которому подключены датчик 13 расхода свежего пара в магистрали 14, задатчик 15 и блок 16 импульсного интегрировани . Блок 16 импульсного интегрировани по входу и выходу соединен с корректирующим регул тором 17, который также соединен с датчиком 18 давлени пара в магистрали 6 отбора.To the input of block 11, a fresh steam flow regulator 12 is connected to a turbine unit, 15 to which a fresh steam flow sensor 13, a unit 15, and a pulse integrator block 16 are connected. The impulse integration unit 16 in the input and output is connected to a correction regulator 17, which is also connected to the vapor pressure sensor 18 in the extraction line 6.
