In a power plant, does the generator consume a very small amount of coal, water, or other forms of e

The synchronous generator emits reactive power and must increase the excitation current of the motor. At this time, the generator current increases since the generator loss = I*I*R, the iron loss in the motor. also increases. It consumes very little energy. The biggest impact of reactive power generation is that it occupies the apparent power of the generator and affects the active power generation capacity. However, no additional equipment is required to generate reactive power. Generators can also reduce excitation current and absorb reactive power from the power grid. Therefore, the power grid often uses generators to regulate the voltage of the power grid.
