Изобретение относитс  к преобразовательной технике, в частности к системам управлени  вентил ми статических компенсаторов реактивной мощности.The invention relates to converter technology, in particular, to control systems for valves of static reactive power compensators.

Известно применение статических компе саторов, например тиристорно-дроссельных дл  регулировани  коэффициента мощности сети, а также дл  регулировани  напр жени  в автономных инверторах. Регулирование осуществл етс , например, путем изменени  угла отпирани  встречно-параллельных тиристоров, соединенных последовательно с линейньпуг дросселем 1 .It is known to use static compressors, such as thyristor-chokes, to control the power factor of the network, as well as to regulate the voltage in autonomous inverters. The adjustment is carried out, for example, by changing the unlocking angle of anti-parallel thyristors connected in series with the line choke 1.

Известно также использование трехфаз- ного компенсатора, состо щего из трех однофазных , одновременно и дл  регулировани  напр жени  или реактивной мощности, и дл  компенсации несимметрии трехфазной системы напр жений. В этом случае систе- ма управлени  вентил ми выполн етс  многоканальной , что позвол ет ввести в канал управлени  вентил ми каждой фазы нар ду с общим сигналом дополнительный сигнал несимметрии 2.It is also known to use a three-phase compensator consisting of three single-phase, at the same time to control the voltage or reactive power, and to compensate for the unbalance of the three-phase voltage system. In this case, the valve control system is multichannel, which allows an additional unbalance signal 2 to be introduced into the valve control channel of each phase along with the common signal.

Поскольку векторы трехфазной системы линейных напр жений образуют замкнутый треугольник, несимметри  напр жений по величине и фазе взаимосв заны. Поэтсхму сигнал несимметрии можно получить путем сравнени  напр жений как по величине, так и по фазе.Since the vectors of the three-phase system of linear stresses form a closed triangle, the asymmetries of the stresses in magnitude and phase are interconnected. Poetrym asymmetry signal can be obtained by comparing stresses both in magnitude and phase.

Получение сигнала несимметрии путем сравнени  величины напр жени  каждой фазы с напр жением уставки приводит к многоканальной системе регулировани  напр жени .Obtaining an asymmetry signal by comparing the magnitude of the voltage of each phase with the setpoint voltage leads to a multi-channel voltage control system.

Получение сигнала несимметрии путем сравнени  фаз выходных напр жений с фазами симметричной опорной системы напр жений исключает взаимное вли ние общего канела регулировани  и канала симметрировани , но приводит к усложнению схемы.Obtaining an asymmetry signal by comparing the phases of the output voltages with the phases of a symmetric voltage reference system eliminates the mutual influence of the common control channel and the balancing channel, but it complicates the circuit.

Целью изобретени   вл етс  устранение несимметрии трехфазной системы питающего напр жени .The aim of the invention is to eliminate the asymmetry of the three-phase supply voltage system.

Это достигаетс  тем, что к входам блоков регулируемой задержки импульсов каждой фазы последовательно с общим сигна-This is achieved by the fact that to the inputs of the blocks of the adjustable delay of the pulses of each phase in series with the common signal
