<p>Equipment for exchanging power, in shunt connection, with an electric power network (N) comprising a reactive impedance element (C, LC) and a voltage source converter (VSC) for mutual connection in series. The power network has a nominal voltage (Un) of a fundamental frequency (f) and a given phase position. The converter is intended for generating a fundamental-tone voltage (US) within a control range (A) which limits the amplitude of the fundamental-tone voltage. The control range limits the amplitude of the fundamental-tone voltage to a value which is lower than the nominal voltage of the power network and comprises generation of a reactive component (USr) of the fundamental-tone voltage with a phase position (Ø) that either coincides with the phase position for the voltage of the power network, or that deviates by 180° electrically form the phase position for the voltage of the power network.</p> |
