Parallel operation synchronous and induction generator on microgrid testbed

Abstract

This paper presents the development of laboratory scale microgrid testbed for student learning consisting of synchronous generator and induction generator that are operated in parallel. Parallel operation is done by maintaining the voltage and frequency according to the standard operation generally at the voltage level of 380 Vll (+ 5% and −10%) and the frequency level 50 Hz (± 1%). Standard operation is performed by making the synchronous generator as a reference parallel to the induction generator. The test results show that parallel operation of synchronous generator and induction generator can work well with synchronous generator as provider of active power and reactive power while induction generator only produce active power.
