Efficiency and operational cost Calculate the investment and operation cost of all three alternatives according to following loading profile over the first 10 years. Assume that energy costs 30 Eur /MWh and the total running time per year is 8300 h. 50 15 Compressor speed [%] Share of operation time [%] Following assumptions must be made: * A Magnetizing current of the motor(s) is fixed. Copper losses (I^2R-losses) are depending about the motor torque. You do not need to separate reactive component (that is fixed) from the real component, assume the whole motor current depends on the torque when calculating copper losses. Machine losses are not influenced by the temperature. Converter losses are depending linearly about the output current. The base value for converter loss must be taken from the table 4. 65 20 Start by generating a separate row for each loading point in excel and reference values in nominal point. Table 4.
