Development of mechanical coupling and exciter system in synchronous generators

Power is generated in a variety of ways, including renewable energy, nuclear power, and burning fossil fuels. The majority our power currently by fuels, mostly natural gas coal, to spin turbines attached an electromagnetic generator. main advantage AC generation that the voltage levels can be altered up down with transformers, allowing electricity sent across long distances loads demand it. excitation system for large synchronous generators few hundred-megawatt ratings becomes very enormous. challenge transmitting such big amount through high-speed sliding contacts daunting. Mechanical coupling exciter essential mitigate problems as corrected output linked directly field winding. This paper aims develop simulation 3-phase diesel engine-based 2 MVA/400 V generator mechanical system. developed machine set deliver 25 % its rating value (500 kW) till time 3 sec. Then, additional 1 MW switched at t=3 sec via circuit breaker. dynamic response current shows reasonable step performance steady-state less than control allows maintain voltage, reactive flow, assist maintaining stability. was accurate when measuring under these changes. analysis help investigate further integration energy sources.
