FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and provides a method and system for controlling line power of a device for the integrated regulation of power flows. Such method for controlling the line power for the integrated power flow control device includes controlling the power on the external loop line, controlling the power on the internal circuit line and controlling the converter valve. Reference values on the side of the converter valve on the side of the Isedref and Iseqref serial connection are calculated by controlling the line power in the outer loop in accordance with the commands for power supply on the Preƒ and Qreƒ line, which are input values, measured power on the UL line and the measured power on the Pline and Qline; the reference value of the output voltage of the Ucreƒ converter is calculated by regulating the current in the internal circuit on the valve side in accordance with the reference current values on the valve side, which are the output values, by controlling the power in the external circuit, the measured current on the valve side, the measured voltage on the valve side; and finally, the converter outputs, in accordance with the reference voltage value, a corresponding voltage for controlling the line power in order to achieve a reference value.
EFFECT: such control method is simple, practical and highly reliable, can quickly and accurately control the line power and perform independent disconnected control of the active and reactive line power.
