FIELD: electricity.SUBSTANCE: invention relates to electrical engineering and can be used in a shaft generator system. The technical result is providing dynamic prevention of short circuiting. The shaft generator system comprises a shaft generator (18), having an inverter (42) with an intermediate voltage loop, with network-side inductance, wherein the inverter (42) with an intermediate voltage loop has at the generator side and the network side a corresponding alternating current rectifier (44, 46), connected to each other at the dc voltage side. The network-side alternating current rectifier (46) has at least two phase modulators, which respectively have an upper and a lower rectifier branches (P1, N1, P2, N2, P3, N3), which respectively have a plurality of electrically series-connected two-pole subsystems (SM1, SM2, ?, SMn), which respectively have a unipolar storage capacitor (C), which is electrically parallel-connected to a circuit of series-connected two semiconductor switches (S1, S2) with a corresponding anti-parallel connected diode (D1, D2).EFFECT: providing a shaft generator system having, as a static frequency converter, an inverter (42) with an intermediate voltage loop, which can be used to maintain the required network reactions and suppress transient operating states.7 cl, 5 dwg |
