Neglect load in motor loads in analytical calculations and reduce circuit to simple RLC circuit. Do the simulations first without the loads and then with the motor (each motor is 30,000 HP) loads modelled as a series R-L circuit ( model motors as voltage behind a reactance, neglect the non-linear load ) in a more complete circuit model. Assume motors operate at pf = 0.8 lagging and 100% efficiency. Problem 6-2 in text book: Neglect load in motor loads in analytical calculations and reduce circuit to simple RLC circuit.

Unformatted text preview: motor (each motor is 30,000 HP) loads modelled as a series R-L circuit ( model motors as voltage behind a reactance, neglect the non-linear load ) in a more complete circuit model. Assume motors operate at pf = 0.8 lagging and 100% efficiency. Problem 6-3 in text book: Neglect the loads for analytical calculations. Problem 6-4 in text book: Neglect the loads for analytical calculations. Problem 6-5 in text book: Neglect the loads for analytical calculations. The book was not very clear on resistance switching. Choose the resistance such that the series R-L-C circuit for energizing the capacitor is critically damped....

### What students are saying

• 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.
