Abstract (en)
[origin: WO0052805A1] The invention consists of a method to greatly enhance the Mvar absorption of a high voltage shunt reactor in response to excess Mvar suddenly appearing on a high voltage transmission system. A high voltage capacitor is connected in series with a shunt reactor in order to increase the reactor voltage, and thereby the Mvar absorption, as a function primarily of the capacitor value in combination with the dynamic impedance of the reactor in the saturated region of the reactor V/I characteristic. The new with the invention is that the Mvar absorption of the reactor is no longer dependent on the system voltage alone. The invention also includes a reactive device consisting of a multi phase shunt reactor with a capacitor connected in series with each phase.
