摘要： A VSC-converter for converting alternating voltage into direct voltage and conversely is controlled so that semiconductor devices of turn-off type connected in anti-parallel with diodes are controlled to be turned on and turned off so that an alternating voltage phase line is alternatively connected to a midpoint (23) of a direct voltage side of the apparatus, the plus pole (7) mad the minus pole (8) of the direct voltage side for generating a train of pulses with determined amplitudes according to a pulse width modulation pattern on the phase output of the apparatus. The midpoint of the direct voltage side is connectable to the phase output through two different so called zero states. The semiconductor devices (13-16, 10, 11) are controlled so that both zero states are each assumed at least once during a half period during which the fundamental frequency component of a voltage set value of the phase output is positive or negative.

摘要： 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.
