Document Summary
Question 1a (16%) a squirrel-cage induction generator (scig) for a wind turbine has the following parameters: 690v (rated line-to- line voltage), four-pole, 60hz, rs = 0. 001 , rr = 0. 0012 , lls = llr = 0. 05mh, and lm = 2. 15mh. All the rotor parameters are referred to the stator side. The rotational losses of the generator are 25kw. The rotor speed of the generator is 1810rpm. 1-1 steady-state equivalent circuit of an induction generator. (4%) determine the total equivalent impedance sz of the scig. The slip: n n n s s s r f. 00556 (negative slip) (1) this is a closed-book exam. No aids other than basic calculators and a formula sheet are permitted. (2) answer all four questions. You must show your steps and derivations clearly to be awarded part marks for your answer. (3) if in doubt on any question, you must clearly state your own assumptions.
