Hi all
I want to know about the basic equation of stator and rotor voltage and power equation of 3 phase asynchronous generator connected to grid.
I also want to know about the load angle of the generator in term of equation and for both stator and rotor.
Kindly help me in this regards
The doubly wound asynchronous generator is a prominent choice for variable-speed energy conversion system due to its improved conversion efficiency and reduced rating converters. To supply rural community located in small pockets and far away from grid utility, stand-alone energy conversion system driven by renewable energy prime movers such as pico hydro and wind turbines is gaining popularity.
There are a lot of interesting books about the topic you are interested in. You can find the information you are looking for in the next books:
1. Abad, G., Lopez, J., Rodriguez, M., Marroyo, L., & Iwanski, G. (2011). Doubly fed induction machine: modeling and control for wind energy generation (Vol. 85). John Wiley & Sons;
2. Wu, B., Lang, Y., Zargari, N., & Kouro, S. (2011). Power conversion and control of wind energy systems. John Wiley & Sons;

Good Luck!
Basically, an Asynchronous Generator(AG) or induction Generator is a type of alternating current generator which is similar to an induction motor to produce power. AG´s principle of operation is by turning the rotors mechanically faster than the synchronous speed. The grid connected AG´s are divided into 2 types, single output and double output. The rotor speed for the both of the types should be greater than the synchronous speed of the revolving field in the air gap of the induction machine. The single output sends the energy from the stator windings to the grid but the other one(double outptu) send the energy from both the stator and rotor windings to the grid. So the equations vary depending on which type of AG you need. Equations for voltage and power can be accessed in the link.
