Abstract
Изобретение относитс к средствам автоматизации энергоблоков. Целью изобретени вл етс повышение надежности и точности регулировани .при изменени х нагрузки энергоблока. Это достигаетс тем, что сигнал с датчика электрической мощности энергоблока подаетс на вход регул тора топлива через адаптивный след щий интегратор, имеющий нуль-орган, выполненный в виде операционного усилител 10, выход которого соединен с двум ключами, выполненными на транзисторах 16 и 17 разной проводимости. В нагрузку этих транзисторов включены обмотки реле 18 и 19, через контакты 28 и 29 которых подключены источники 26 и 27 посто нного напр жени к входному делителю напр жени интегратора 11, выполненному на резисторах 30s 31 и 32. При изменени х нагрузки энергоблока интегратор 11 интегрирует сигнал с резисторов 30, 31 или 32 до тех пор, пока его выходной сигнал станет равным входному сигналу усилител 10, подаваемому на зажимы 22 и 23 от датчика электрической нагрузки энергоблока. 3 ил„ 58This invention relates to the automation of power units. The aim of the invention is to increase the reliability and accuracy of regulation with changes in the load of the power unit. This is achieved by the fact that the signal from the electric power unit of the power unit is fed to the input of the fuel regulator through an adaptive tracking integrator having a zero-body, made in the form of an operational amplifier 10, the output of which is connected to two keys made on transistors 16 and 17 of different conductivity . The load of these transistors includes the windings of relays 18 and 19, through contacts 28 and 29 of which sources 26 and 27 of constant voltage are connected to the input voltage divider of integrator 11, made on resistors 30s 31 and 32. When the load of the power unit changes, integrator 11 integrates the signal from the resistors 30, 31 or 32 until its output signal becomes equal to the input signal of the amplifier 10 supplied to the terminals 22 and 23 from the electrical load sensor of the power unit. 3 or 58
