Solar PV Grid Tied Training System

Solar PV Grid Tied Training System is a compact version of an actual Solar PV Grid Tied power plant. The system enables user to study wiring and interconnections of different components involved in the system to develop basic understanding of working and operation of a Grid connected system. A user can understand underlying principles power electronics, its applications in power system and challenges like harmonics and grid synchronisation by doing various experiments. The system also provides scope for further research.

The system utilises a 500 Watt. solar PV panels installed at a rooftop which connects to the control unit installed in the lab. The control unit has a grid tied inverter and a measurement panel with various measuring instruments that calculate production and consumption of energy. If the total power produced by solar panels exceeds power consumed by loads then the extra power is transferred to the grid whereas is if power produced by solar panel is less than the power consumed then the loads will consume power from solar panels as well as the grid.

As several institutions don’t allow to feed the power generated by solar panels to their utility grid, Ecosense utilises a virtual grid installed in the Grid box connected to control unit. The virtual grid acts as the utility grid for experimentations. User can switch between actual and virtual grid anytime.
