At the Department of EEE, GCE Kannur we have the following hardware setup.

1) Grid Connected Three Phase Inverter with Power Quality Improvement

The complete system was assembled in our lab using Semikron inverter module (three phase), LEM sensors (voltage and current measurement), 6N136 based gate drive, interfacing inductor and RC ripple filter. The system can operate as a DSTATCOM (providing power quality improvement) or as a renewable energy based inverter (active power injection + power quality improvement). The variety of local loads can be connected. (Non linear, RL, combined). The complete system is controlled using dSpace MicroLab Box. For the control purpose, Matlab/Simulink and Controldesk softwares are used.

2) Wind Turbine emulator – PV emulator – Fuel cell - Battery Based Microgrid System (With grid connection)

This microgrid system consists of a wind turbine emulator, PV emulator and fuel cell as sources and a lithium ion battery for energy source. These sources are connected to a 120 B DC link through DC-DC converters. Then the system is connected to the grid through an inverter and transformer. The system is controlled using an FPGA based controller and LabVIEW software This system has been provided by Ecosense Sustainable Solutions Pvt. Ltd, Delhi.
