Description

Изобретение oTHOcktCH к способам защиты генераторов, прриводимых первичными двигател ми , от чрезмерного повышени  частоты вращени . Оно может быть использовано в системах автоматизации электроэнергетических систем . Известны способы предотвращени  «разноса генераторов, приводимых первнчиым  дв гател ми, путем их экстренной остановки при достижении аварийной частоты . вращени  {). Наиболее блкзок к предложенному способ предагвращени  «разноса генератора, параллельно работающего, по крайней мере, с одним генератором на общую нагрузку через генераторные автоматы, путем остановки первичного двигател  при достижении аварийной частоты вращени  2. Первичный двигатель останавливают за счет прекращени  подачи в двигатель топлива или воздуха (или одновременно и топлива, и воздуха) и одновременно отключают нагрузку (выключением генераторного автомата). При экстренной остановке агрегата по сигналу аварийной частоты вращени  при наличии неисправностей в исполнительной цепи остановки возможно создание условий, способствук цих дальнейшему увеличению частоты враще к  за счет полного сброса полезной нагруз ки - в йключени  генераторного автомата и отклнэченнй аварийного генер;атвра от сети. Целью изобретени   вл етс  повы{иеиие надежности за счет у&еличени  нагрузки на аварийный геаерзтор, Поетавлен а  цель достигаетс  тем, что дл  предотвращени  «разноса генератора, парал-, лельно работающего,  о крайней мере, с одним другим генератором на общую нагрузку через генераторные автсшаты, путем остановки :TiepBH iiioro дввгате   при досп жёнаи аварвй1ной частоты вращени , одновременно с с г алом на остановку первичного двигател  аварийного генератора подают сигнал на отключение генераторного автомата другого ген атор& , при этом генераторный автомат аварийного генератора остаетс  включенным. Пред ойжнный снособ по сн етс  чертежом, FeHepaTtqibi I к 2, приводимые первичными двигател ми 3 и 4, подключены к сибщей нагрузке - ш иам 5 электроэнергетической системы через генераторные автоматы б и 7. Первичные двигатели 3 и 4 оборудованы блоками 8, 9 экстренной остановки и датчиками 10, М аварийной частоты вращени , св зйниъ й  с логическими блоками соответственно 12 и 13. Одиоврейенно каждый логический блокThe invention of an OTHOcktCH to methods for protecting generators, driven by primary motors, from excessively increasing rotational speed. It can be used in automation systems for electric power systems. Methods are known for preventing the "spacing of generators driven by the first engines by their emergency stop when the emergency frequency is reached. rotation {). Most of the proposed method of preventing the generator from spacing, operating in parallel with at least one generator for a total load through the generator machines, stops the prime mover when the emergency speed 2 is reached. The prime mover is stopped by stopping the supply of fuel or air to the engine (or at the same time both fuel and air) and at the same time disconnect the load (by turning off the generating automatic machine). In case of an emergency stop of the unit, the emergency frequency of the rotational signal in the presence of faults in the shutdown actuator circuit can be created to further increase the rotational speed due to the complete reset of the payload - when the generator is turned off and the emergency generator is disconnected from the network. The aim of the invention is to increase reliability due to the increase in the load on the emergency geezer. This goal is achieved by the fact that in order to prevent the generator from running in parallel with at least one other generator to the total load through the generator Autoshorts, by stopping: TiepBH iiioro two at the speed of the engine and emergency speed, simultaneously with the stop of the primary engine of the emergency generator give a signal to turn off the generator machine of another gene & while the generator automaton of the emergency generator remains on. The pre-assembly procedure is illustrated in the drawing, FeHepaTtqibi I to 2, driven by the prime movers 3 and 4, connected to the sibling load — power grid 5 of the power system through the generator machines b and 7. Primary motors 3 and 4 are equipped with emergency stop blocks 8, 9 and sensors 10, M of the emergency frequency of rotation, which are connected with logical blocks 12 and 13 respectively. Each logical block is certified
