In a generator running on fossil fuels, chemical energy is converted to heat energy through the combustion of fuel. The heat energy is then converted to kinetic energy in the prime mover. The kinetic energy is again converted to electrical energy through the principle of electromagnetic induction inside the alternator.

In power systems, there are cases where two or more generators run in synchronism with each other. In such cases, if one generator's prime mover fails, it operates in the motoring mode, thereby drawing power from the grid to run at synchronous speed. This causes unnecessary overburden on the healthy generators. To prevent this, we … Read more
