Ex 5.2 (4ed) (ex 4.2 5 ed) || Synchronous Generator || Effect of Load Changes(Chapman )

EM 5.8(1) (E)(Ch) ||Example 5.2 ||Synchronous Generator
An increase in the load increases the load current drawn from the generator.
Increase in the load is an increase in the real and/or reactive power drawn from the generator.
The magnitude of the internal generated voltage is constant.
If lagging loads ( inductive loads) are added to a generator, the terminal voltage decrease significantly.
If unity-power-factor loads (no reactive power) are added to a generator, there is a slight decrease in the tenninal voltage.
If leading loads ( capacitive load) are added to a generator, the tenninal voltage will rise.
Example 5.2: A 480-V, 60Hz -delta connected four-pole Synchronous generator has
the OCC shown in Figure 5--23a. This generator has a synchronous reactance of 0.1 n
How much field current is required to make Vt equal to 2300 V when the generator is mlUling at no load?

Very good. Thanks 🙏🙏🙏🙏🙏🙏

[@asim_hussain]

JazakAllah Sir..
Incase of Y connected generator do we have to use terminal voltages to find corresponding field current from open circuit curve or phase voltages Ea..?

[@ElectricalEngineeringAcademy]

Yes. But always convert and work with single phase equivalent circuit
