Plant data which are represented in the graph are:
- Coal Flow (T/h) : black color signal (Scale Normal)
- Gross Power (MW) : red signal (Scale Normal)
- Natural Gas Flow (Nm3/h) : blue signal (scale by a factor of 100)
The graph represents a period of 4 days. The data are obtained with daily periodicity at 08:20, 14:20 and 20:20.
