In this paper, the problem of real implementation of a transmission grid was addressed. In today's modern society, electricity is the most important form of energy for industry and society. A reliable and stable electrical power system is therefore essential. The growing amount of renewable energy sources leads to wheeling electrical power over long distances and to the growth in power electronics-based generation. Both affect the behavior of the electrical power system. The objective of this

Additionally, this setup allows to change the rotational inertia and analyze all terminal quantities with phasor measurement units. The control structure of this island grid should reflect the reality as close as possible. All this together enables to study dynamic phenomena with a real small power system. With this laboratory implementation electromechanical swings such as inter-area oscillations after disconnecting a tie-line, changing loads and generation or tripping a synchronous machine can be shown.
