СПОСОБ АВТСЖАТИЧЕСКОГО РЕГУЛИРОВАНИЯ ПИТАНИЯ В ПРОЦЕССЕ ПУСКА ДВУХНИТОЧНОГО ПРЯМОТОЧНОГО ПАРОГЕНЕРАТОРАMETHOD OF ADMINISTRATIVE REGULATION OF POWER SUPPLY IN THE PROCESS OF STARTING A TWO-DIRECT CURRENT STEAM GENERATOR
Изобретение относитс к теплоэнергетике и может быть использовано, например, дл регулировани питани энергоблока тепловой электростанции при пуске.The invention relates to a power system and can be used, for example, to regulate the power supply of a thermal power plant at start-up.
Известен способ i автоматического регулировани питани в процессе пуска двухниточного пр моточного парогенератора , снабженного в каждой нитке сбросным и питательным.клапанами ,, путем изменени положени сброс ных клапанов по сумме двух сигналов, один из которых пропорционален скорости изменени производительности насоса, а другой - давлению питатель- . ной воды в соответствующей нитке 03The known method i automatically adjusts the power during the start-up of a double-filmarted steam generator equipped with waste and feed valves in each line by changing the position of the discharge valves by the sum of two signals, one of which is proportional to the rate of change in pump performance and the other to feed pressure -. Noah water in the appropriate string 03
Недостатком известного способа вл етс невысока точность регулировани , св занна со значительной инер-м ционностью участка сбросной клапанрасход воды.The disadvantage of the known method is the low accuracy of the adjustment, which is associated with the considerable inertia of the section, the waste valve, water flow.
Цель изобретени - повьшеше качества регулировани .The purpose of the invention is higher quality regulation.
Поставленна цель достигаетс тем, что дополнительно определ ют сигна-. лы по скорости перемещени питательных клапанов и по полученным сигналам корректируют изменение положени соответствующих сбросных клапанов.This goal is achieved by additionally determining the signal. According to the received signals, the position of the corresponding relief valves is corrected according to the speed of movement of the feed valves.
На чертеже приведена блок-схема устройства, реализующего предлагаемый способ.The drawing shows a block diagram of a device that implements the proposed method.
Устройство содержит регул торы I, -2 и 3 питани , воздействующие на регулирукнцие клапаны 4 и 5 потоков и питательный масос 6, и регул торы 7 и 8, поддерживающие давлени среды по потокам 9 и 10 воздействием на сбросные клапаны 11 и 12 потоков. Схе ма также включает устройства 13 и 14 динамических св зей.The device contains regulators I, -2, and 3 supply, acting on the control valves 4 and 5 flow and nutrient masos 6, and controllers 7 and 8, supporting the pressure of the medium in flows 9 and 10, the impact on the waste valves 11 and 12 flows. The scheme also includes dynamic link devices 13 and 14.
Устройство работает следующим образом .The device works as follows.
При по влении сигнала небаланса на входе регул тора 1 (З) выходной сигнал этого регул тора передаетс к регулир)гющему клапану 4 (5) потокаWhen the unbalance signal appears at the input of the regulator 1 (G), the output signal of this regulator is transmitted to the regulating valve 4 (5) of the flow
