Abstract
The use of micro hydro energy for electricity generation in Indonesia is currently increasing along with the launch of the energy independence village program which continues to grow in several regions. In this study, the design and analysis of AC-DC-AC converter is applied to asynchronous/induction generators connected in parallel with 50-kW Micro Hydro Power Plant. The AC-DC-AC converter consists of a Generator Side Converter (GSC) and a Load Side Converter (LSC) which are installed back to back via the DC-Link network. The effectiveness and dynamic characteristics of the controller design were evaluated and analyzed through simulation using the PSCAD program. Simulation analysis is divided into 2 fault scenarios, namely: (1) Analysis of small disturbances in the form of changes in load and generator rotation differences, and (2) Analysis of large disturbances due to short circuits in the transmission network. The results show that the control system is able to stabilize and regulate the flow of power against changes in load and permanent disturbances.
