На чертеже дана структурна  схема описываемого устройства. Устройство содержит блок I измерени  отклонени  напр жени  от заданного уровн , включенный на трансформатор 2 напр жени , блок 3 измерени  внутреннего угла, соединенный с трансформатором 2 и датчиком 4 угла, и тиристорный нрерыватель 5, включенный нааллельно шунтовому реостату 6.

Следовательно, работоснособность нредлагаемого устройства сохран етс  нри лю-бых носадках нанр женн  собственных НУЖД.Devices for controlling the excitation of a synchronous generator operating in the mode of reactive power consumption with an electromotive excitation system are known, comprising a sensor for the internal angle of the machine, a measuring unit for deviating the voltage from a predetermined level, a measuring unit for the internal angle of the machine, and a power unit executed as a controlled tyrnstorny a circuit breaker, the control values of which are connected to a voltage deviation measurement unit and an internal angle measurement unit. In order to increase the reliability of the excitation system and the landings of auxiliary needs, the proposed device has an OR logic circuit, one input of which is connected to an independent source; 1ku of rectified voltage, the other to the exciter core, and the output to the thyristor interrupter. The drawing is a block diagram of the described device. The device contains a block I measuring the deviation of voltage from a predetermined level, connected to a voltage transformer 2, a unit 3 measuring the internal angle connected to a transformer 2 and an angle sensor 4, and a thyristor interrupter 5 connected in parallel to the shunt resistor 6. The I-up and downstream chopper 5 performs Through the logic circuit "OR 7 from the value of the exciter core 8 or rectifier 9, it is switched on from the voltage of its own needs. The thyristor breaker 5 has a fixed open state time and is varied over a wide range of closed state time, which is determined by the total CiUna.iOM. Not received from the units / 3. The ratio of the times of the open and closed states of the three-way interrupter determines the average value of the current in the non-winding 10 of the excitation of the exciter. Thus, depending on where the voltage at the moment is higher, the price of a triacular interrupter 5 — the excitation winding 10 of the driver is injected through the circuit “OR 7 from the core of the driver 5 or from the auxiliary voltage through the rectifier 9. In the normal circuit, Under the conditions of self-voltage, their own needs are driven by an independent scheme, and when their own equipment disappears, it follows a self-excitation scheme. Consequently, the operability of the proposed device is retained at any time for its own NEEDS.
