This option of the Hydro Power Generation Trainer can work in both off-grid and on-grid modes. It consists of a 3-phase synchronous generator moved by a real Pelton turbine. The trainer simulates real water flow using a pump. With the manually controlled valves, it allows to simulate different water flow and head pressure and investigate the generator performance in different conditions. In off-grid mode, it allows investigating the supply of local loads, as well as voltage and frequency regulation. In on-grid mode, it allows implementing the synchronization with the mains power grid.
