Voltage and frequency regulation of a standalone induction generator by reduced-rating power electronic compensators - comparative evaluation

In this paper are considered two fundamental topologies of power electronic compensators for voltage and frequency control of a standalone self-excited induction generator (IG) system. These are voltage and current source inverter based shunt compensators with energy storage. The aim of this study is to assess main features of both topologies in dynamic and steady-state IG operation. The whole system is modelled with the aid of the TCad circuit simulator. Comparative simulation tests are performed for active and reactive load power variations. From steady state switching waveforms, voltage and current source converter losses are evaluated. Concluding remarks focus on comparative specification of converter topologies for reduced rating shunt compensators in a standalone IG system applications.
