Generators R Us (GRU) is a leading manufacturer of partible electric generators used for emergency power supply in both civil and private disaster situations. Each year it produces 16,000 of its model HI-360 units. This model used two bearings, which the company purchases from an outside vendor. A review of accounting and usage records reveals the following information: labour for installing the bearings = $8 per generator; • per-unit cost of bearings = $25; • delivery charges per order =...

Several generators pollute the environment by emitting carbon dioxide. Generators have different costs of reducing carbon emissions. The government wants to put a cap on total emissions. Putting a cap on each generator is more efficient compared to issuing tradeable emissions permits to each generator. Is this true or false? Explain your answer.

Several generators pollute the environment by emitting carbon dioxide. Generators have different costs of reducing carbon emissions. The government wants to put a cap on total emissions. Putting a cap on each generator is more efficient compared to issuing tradeable emissions permits to each generator. Is this true or false? Explain your answer elaborately.

A 45-MVA, 13.8 kV synchronous machine is operating as a synchronous condenser, as discussed in Appendix D (section D.4.1). It’s short-circuit ratio is 1.68 and the field current at rated voltage, no load is 490 A. Assume the generator to be connected directly to an 13.8 kV source a. What is the saturated synchronous reactance of the generator in per unit and in ohms per phase? The generator field current is adjusted to 260 A. b. Draw a phasor diagram,...

USE MATLAB. PROVIDE MATLAB CODE FOR CALCULATIONS AND GRAPHS! A salient-pole synchronous generator with saturated synchronous reactances Xd = 0.78 per unit and Xq = 0.63 per unit is connected to a rated-voltage infinite bus through an external impedance Xbus = 0.09 per unit. a) Assuming the generator to be supplying 0.25 per unit rated real power, add a plot of the per-unit armature current as a function of field excitation as the field current is varied in the range...
