Abstract
Micro gas turbine generation system (MGTGS) is a distributed power source with the prospect of development in the fields of renewable energy and emergency supplies in hospitals and upscale buildings. The MGTGS has the advantages of low emission and high comprehensive efficiency. In this paper, the equivalent model of the micro-gas turbine and the mathematical models of the permanent magnet synchronous generator (PMSG) and the load side converter are established. The permanent magnet synchronous generator side converter is controlled by rotor flux orientation based vector control to stabilize the DC bus voltage. And the constant-voltage constant-frequency (V/F) control strategy is adopted for the load side converter. Modeling and simulation of the islanding generation control strategy of MGTGS are implemented. The simulation results show that the control strategy can stabilize the load voltage and frequency well.
