Description
(54) СИСТЕМА АВТОМАТИЧЕСКОГО РЕГУЛИРОВАНИЯ ПРИ ПУСКЕ ДВУХНИТОЧНОГО ПРдаЮТОЧНОГО ПАРОГЕНЕРАТОРА .(54) AUTOMATIC REGULATION SYSTEM FOR START-UP OF TWO-THREAD POWER SPEED GENERATOR.
II
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 and supply the power unit of a thermal power station during start-up.
Известнасистема автоматического регулировани при пуске двухниточного пр моточного парогенератора со сбросным и питательным клапанами в каждой нитке, содержаща регул тор общего расхода воды, подключенный к регулирующему органу насоса, регул торы давлени воды в каждой нитке, соединенные с соответствующими датчиками и дифференциаторами и подключенные к своим сбросным клапанам, и датчики положени питательных клапанов и регулирующего органа насосаThe known system of automatic control during the start-up of a double-stranded steam generator with waste and feed valves in each line, containing a regulator of the total water flow connected to the regulator of the pump, water pressure regulators in each line, connected to the corresponding sensors and differentiators and connected to their own wastewater valves and feed valve position sensors and pump regulator
РЗ.Rz.
Недостатком известной системы вл етс .невысока точность регулировани , св занна со значительной инерционностью участка сбросной клапан - расход воды.A disadvantage of the known system is the low control accuracy associated with the considerable inertia of the waste valve — water consumption.
Цель изобретени - повышение качества регулировани .The purpose of the invention is to improve the quality of regulation.
Поставленна цель достигаетс тем, что к каждому дифференциатору подключены датчик положени регулирующего органа насоса и датчик по ложени соответствующего питатель|Ного клапана.The goal is achieved by the fact that the position of the regulator of the pump and the position sensor of the corresponding valve feeder are connected to each differentiator.
На чертеже приведена блок-схема предлагаемой системы.The drawing shows a block diagram of the proposed system.
toto
Схема содержит регул торы 1, 2 и 3 питани , воздействующие на регулирующие клапаны 4 и 5 потоков и пии тательный насос 6 и регул торы 7 и - 8, поддерживающие давление среды по потокам 9 и 10 воздействием на сбросные клапаны 11 и 12 потоков. Схема включает также дифференциаторы 13 20 и 14 и датчики 15, 16 и 17 положени регулирующих клапанов первого и второго потоков и регулирующего насоса.The scheme contains supply controllers 1, 2, and 3, acting on flow control valves 4 and 5 and feeder pump 6 and flow controllers 7 and 8, which maintain the pressure of the medium through flow 9 and 10 by affecting discharge flow valves 11 and 12. The circuit also includes differentiators 13 20 and 14 and sensors 15, 16 and 17 of the position of the first and second flow control valves and the control pump.
Схема работает следующим образом.The scheme works as follows.
