Analyse several voltage and current situations in different loading scenarios in a simplified radial (transformer to consumption) medium-voltage power system example. There are only 2 nodes in the 35 kV line – node 0 from the 110/35 kV and node 1 with one consumer. The physical characteristics of the line and the loading scenarios are individualized for each student – please see the attached file Excel “WM9P3 Task1 data” for your particular data set.  Briefly reflect on the complexity of the calculations for known input or output voltage, as well as for fixed or voltage-dependent consumption in this simple power system model.  Analyse and discuss the sensitivity of the voltage drop [in % of amplitude and the degrees of phase] with respect to the current level [in %] and to the power factor.

Question 13 of 15 Determine: The figure below shows a vapor power cycle that provides process heat and produces power. The steam generator produces vapor at 500 lbf/in.², 800°F, at a rate of 8 x 104 lb/h. Seventy percent of the steam expands through the turbine to 10 lbf/in.² and the remainder is directed to the heat exchanger. Saturated liquid exits the heat exchanger at 500 lbf/in.² and passes through a trap before entering the condenser at 10 lbf/in.² Saturated liquid exits the condenser at 10 lbf/in.² and is pumped to 500 lbf/in.² before entering the steam generator. The turbine and pump have isentropic efficiencies of 85% and 89%, respectively. For the process heat exchanger, assume the temperature at which heat transfer occurs is 465°F.

1. Electrical explosions directly into the face of a person working on or near energizedelectrical equipment can and will cause serious injury or death. OSHA laws and NFPA70E have strict safety requirements for working on electrical equipment. The basicrules are to turn off the power before working on the equipment and to wear the propertype of nonflammable clothing. To further provide safety for the worker, the NationalElectrical Code has a requirement pertaining to arc-flash hazard warning. This requirement is found in of the NEC.
