SHAFT-DRIVEN GENERATOR SYSTEM

摘要

The invention relates to a shaft-driven generator system having a shaft-driven generator (18). According to the invention, a voltage source inverter (42) having a network-side inductance is provided, wherein said voltage source inverter (42) has a converter (44, 46) on the generator side and on the network side, which are linked to each other on the direct-voltage side, and wherein the converter (46) on the network side has at least two phase modules, which each have an upper and a lower valve branch (P1, N1, P2, N2, P3, N3), which each have a plurality of two-pole sub-systems (SM1,..., SMn) connected electrically in series, which sub-systems each have a unipolar storage capacitor (CSM), to which a series circuit of two semiconductor switches (S1, S2) that can be switched off is connected electrically in parallel, each semiconductor switch having a diode (D1, D2) connected antiparallel. Thus, a shaft-driven generator system is obtained that has a voltage source inverter (42) as a static frequency converter. By means of the voltage source inverter, the required effects on the network can be complied with and transient operating states controlled.
