25.2 Power Plant
|C1||Yield||Yield of the thermal power plant|
|C3||Fuel||Combustible used (0: Fuel, 1: Gas)|
|C4||FF||Form factor of the power curve. Measures the variation of the power throughout the day.|
|C5||Steam Temp.||Live steam temperature|
|C6||Air Temp.||Air temperature (environment)|
|C7||Seawater Temp.||Seawater temperature (cold source)|
|C8||Day||Weekday (1: Monday, 2: Tuesday, …)|
First, it should be clear that the variable Day, as such (qualitative variable with more than two categories), cannot be a candidate to be included in the model. However, what can be done is to encode it as 0=working day (Monday to Friday) and 1=weekend (Saturday and Sunday). This distinction seems reasonable to the technicians, because on weekends there is less demand and that could affect the performance of the power plant.
