descibe in detail the construction of a 3 phase induction generator, including the components.
The circuit below represents a three-phase, 60 Hz, synchronous generator supplying powerto an induction motor. Since the system is balanced, the diagram represents only Phase A of the system. Assume the motor magnetizing reactance, the motor friction loss, core loss, and windage loss are neglected to simplify the circuit. In addition, all losses in the generator are ignored Generator rating: 10.0 MVA and 13.8 kV (line voltage); Motor rating: 9.0 MW output, 4 poles, 60 Hz, R10.9 Ohm and R2...

1. When the induction generator is running slower than synchronous speed, which way do the Watts and Vars flow (into the generator or out of the generator)? 2. When the induction generator is running at or above synchronous speed which way do the Watts and Vars flow? 3. When you plotted the motor saturation curve, assuming the normal operating voltage is just below the knee of the curve, what did you determine the normal operating voltage to be?
I want to solve this problem step by step. Thanks (35 points) Induction Generator Real Power Generation. A three phase, 220V line to line, six pole, 60Hz, wye connected induction machine operates at rated voltage as a generator at a slip of-0.04. Its equivalent circuit parameters are the same as those in problem #1. The input mechanical power at the rotor (this is a generatorl) is 5.2kW. The core losses are 200Watts; friction and windage losses are 17 Watts; treat...
Prelab 1. In your lab notebook draw the schematic diagram for a three-phase wye-connected induction motor with its three-phase stator winding connected to the three-phase power supply through 25-Ω resistors. Connect two er analyzers in the circuit (between the 25-Ω resistors and the motor) to read the total power absorbed by the induction motor. What is the function of the resistors inserted in the circuit? 2. After reading this lab handout, draw the circuit diagram for the induction motor-synchronous generator...
If a 3-phase induction motor is to be fed by a fixed 50 Hz supply voltage, is it possible that the induction motor operates at a speed of 4000 RPM? YES/NO? WHY?
3 phase generator (80MVA, 86.5kV) with reactance 20ohm/phase, at 0.8 lagging power factor. If generated emf is 40kV per phase, what is the maximum 3 phase power generated before falling out of synchronism?
consider that an induction motor is connected to a 3 phase source and the motor is rotating in a particular direction. if the connections at the two terminals of the motor are interchanged, what will be the effect of the motor?
A three phase induction motor draws a starting current which is five times the full load current with direct on line starting, while developing twice the full load torque. Q2.1. Based on the two facts that starting current is proportional to the applied voltage and that the starting torque is proportional to the square of the applied voltage, determine voltage (as a per cent of rated voltage) required to obtain a starting torque equalling the full load torque.
