Spring 2009 EE 422/522: Final Exam NAME: STUDENT NUMBER: 1. Power flow solutions – Fast Decoupled Newton-Raphson algorithm (20 points): Perform one interation using the fast decoupled Newton-Raphson algorithm assuming a flat start. Line admittances are given in the diagram. 2. Transient stability (25 points) : A generator is connected to a transmission lines as sketched below. A fault occurs at the location indicated in the diagram (next to the bus). The fault is temporary so that when it clears the line remains in service. Find the critical clearing angle and time to ensure stability. All values are given in per unit. Bus 1 Bus 2 (slack bus) P 2 =2.0 Bus 3 P 3 =-4.0 Q 3 = -1.0 (PQ bus) E a =1.25 ∠δ P m =0.75 H=3.0 j0.8 j0.2 V=1.0 Fault

3. Iterative equations (15 points): It is desired to find the solution to the equation below. (a) Assume a starting guess of x= 0.75 π and perform one iteration using the Newton-Raphson method. BE SURE TO SHOW YOUR WORK. 4. Fault current calculations (25 points): Consider two generators in parallel connected

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
