The controller for damping such oscillations includes a phasor measurement unit (PMU) and a power oscillation damper (POD) controller. Each oscillating mode signal is damped and then superposed to derive a control signal. A feedback controller is used to feedback the control signal to a power flow control device in the power system.

    摘要: A limitation of the interaction between cascaded tap changers and/or between a tap changer and a shunt compensator independently of any real-time communication between the respective controllers is disclosed. Coordinated voltage control in distribution networks can be achieved by an adaptive updating or tuning of control parameters DB4, TD4 of a voltage control unit controlling a second voltage control device, depending on instantaneous or actual operating conditions evaluated by the voltage control unit itself. Instead of using constant control parameters initially set by a commissioning engineer, the parameters are updated based on a voltage level UP4, which in turn is responsive to or affected by any control action performed by a first voltage control device neighboring the second voltage control device. The voltage control unit calculates a deviation of an instantaneous value of the voltage level from a reference value, and translates or maps this deviation to an update of its dead bands and/or time delay characteristics. Hence, the voltage control unit can anticipate, or determine a likelihood of, a control action of the first voltage control device, without the need for a real-time transmission of this information to the voltage control unit.

    摘要: A method for determining an equivalent impedance of a transmission section of an electrical network, includes representing the transmission section as having at least two interfaces with other sections of the network. For each interface, a voltage phasor and a current phasor flowing through the interface are determined from simultaneously made measurements at the interfaces. From the phasors, the equivalent impedance is calculated. The required simultaneousness of the phasor measurements is achieved by means of Phasor Measurement Units (PMUs) that are synchronized via the Global Positioning System (GPS).
