Question

Which of these statements is not correct regarding equal area criterion?

• A. The principle of this method consists of the basis that when $\delta$ oscillates around the equilibrium point with constant amplitude, transient stability will be maintained.
• B. This method is applicable to multi -machine system directly
• C. This method partially eliminates the calculation of swing equation.
• D. It can also determine the maximum limitation of the load that system can take without exceeding the stability limit.
