- This is a concept of stability limit.
- It involves :
1.) Torque angle.
2.) Additional power load.
3.) Stability limit.
- There here is an initial output at the beginning and a change in output when an additional load is added but not exceeding the stability limit.
- We have A₁ which is area under the graph for the initial output and A₂ which is area under graph after the changed output.
- I have done calculations in the image below. Find working in the image and also formulae and more explanation.
