Select the type of machine best suited for the application. $($DC$/$AC$/$Stepper$/$BLDC$/$Synchronous$)$ In the case of DC machines, the type, e$.$g$.$ shunt$-,$ series$-$ or compound machine should also be selected. In the case of AC induction machines, it should be specified if it should be a wound rotor or squirrel cage rotor. Please do this for the following topic: $8.$ Alternator$/$Generator systems are generally used where grid electricity supply is not accessible or intermittently during load shedding. Assume a suitable internal combustion engine is available but select the speed at which it should be driven. Use the given physical parameters, select a suitable machine, drive, speed reduction$/$increase system and protection devices. Since people are involved, mention some of the safety features that need to be addressed either by the electrical engineers or mechanical engineers. a$.$ Enclosed in a small building, Output voltage $=100$V dc$,$ Output power $=5$kW$,$ Design fuse overcurrent protection and voltage surge protection. b$.$ Open$-$air, Single$-$phase output voltage $=220$V ac$,$ Output power $=2$kW$,$ Frequency $=50$ Hz$,$ Fuse overcurrent protection and temperature monitoring is required. c$.$ Three$-$phase output voltage $=380$VL$-$L ac$,$ Output power $=15$kW$,$ Frequency $=50$Hz$,$ Loss of phase monitoring and fuse overcurrent protection is required. d$.$ Output voltage $=300$V dc$,$ Output power $=2$kW$,$ Fuse overcurrent protection and bearing vibration monitoring should be implemented. e$.$ Single$-$phase output voltage $=220$V ac$,$ Output power $=2$kW$,$ Frequency $=50$ Hz$,$ Electronic overcurrent protection and electronic undervoltage protection is required. f$.$ Three$-$phase output voltage $=380$VL$-$L ac$,$ Output power $=15$kW$,$ Frequency $=50$Hz$,$ Fuse overcurrent protection and phase imbalance monitoring is required. g$.$ Output voltage $=330$V dc$,$ Output power $=2\mathrm{.}4$kW$,$ Fuse overcurrent protection and temperature monitoring should be implemented. Number of poles of induction machines should be specified if not given. The necessity for star$-$delta starters should be stated. The speed of the motor$/$generator$/$alternator should be calculated. Power and torque $($produced or required$)$ should be calculated for the machine. Gear$/$Pulley$/$Sprocket ratios should be designed if required. Current drawn from supply should be calculated in order to design and select protection devices. The type of protection will be specified but the device selection will be the task of the student and it must be different to any of the other students working on the same topic. $($Overcurrent$,$ Over$-$ and under$-$voltage, Over$-$speed, Temperature monitoring, Bearing noise monitoring etc.$)$ Cooling aspects should be addressed if required. Drive selection if required $$ Soft starter, VSD etc. You have to do your own research on the type of load, eg$.$ if it is a pump, what speed should it be driven at for the desired flow rate and pressure. Your understanding of the load and the system at large have to be reflected in the report. You may select off$-$the$-$shelf products as examples, provided that the specifications are met. External factors such as cable mass and the amount of water in vertical pipes should be carefully considered. All assumptions should be stated and all choices should be motivated very well. The design and findings should be typed in a report of no longer than $10$ A$-4$ pages, single$-$sided. Each student needs to have a meeting with the lecturer to discuss the design after completion and assessment. During this meeting the lecturer may ask any question pertaining to the design process. Labeled figures and circuit diagrams should be presented to show what the system looks like, what components it comprises of and what the ratios of pulley systems or gearboxes are. The estimate cost of machines, drives and protection devices should be included in a table. In some cases you will find it on the websites of suppliers and sometimes you have to request a quotation. The first page of the datasheet of the machine, drive or protection unit selected should be added as an appendix. Evaluate, discuss what you would do differently if you had to do it again. Design processes normally require more iterations after the first round. If time allows it$,$ you may do a second iteration or simply mention what you think you may need to reconsider in a second iteration. Also add any other aspects of importance or interesting information.
