Description
щем органе равен нулю и напр жение усилител 9 равно нулю.The common organ is zero and the voltage of amplifier 9 is zero.
При уменьшении угла запаса устой-ШВОСТИ ниже допустимого из-за понижени напр жени ведущей сети или повышени напр жени иа входе инвертора в суммирующем органе течет ток на входе усилител 9 по вл етс напр жение , которое через систему 10, II управлени воздействует нд управл емый выпр митель .12, увеличива фазу углов регулировани последнего и уменьша , таким образом, входное капр женне инвертора.When the safety margin decreases below the allowable one, due to a decrease in the voltage of the driving network or an increase in the voltage, the input current of the amplifier 9 in the summing organ flows a voltage that, through the system 10, II control, acts on the controllable voltage. The rectifier .12, increasing the phase of the control angle of the latter and thus reducing the input voltage of the inverter.
