The Results Page shows historical pump volumes and energy consumption and gives estimates of energy reduction.
It can be queried for any period with a one-day resolution. It also gives values for the current day. To avoid any issues with time zones and changes between standard and daylight-savings time, the days always begin and end at midnight, Greenwich Mean Time.
The top graphs plot volume produced, specific energy the second bar graph shows energy reduction and % operation in DPO Automatic Mode.
Estimated Energy Reduction
This calculation is performed once a day based on the day’s volume pumped, energy used, reservoir levels, and a baseline calculated based on historical data.
Projected Energy Reduction
The projected energy reduction for the current day is based on the day’s volume and energy consumption extrapolated to a full day.
DPO Mode Percentage tells how much of the time the pump station was operated according to the recommendations of the DPO.
For a pump station running in Automatic Mode (in which the PLC uses recommendations from the DPO to select pumps and pump speeds), the DPO Mode percentage includes all the time the DPO is enabled.
For a pump station running in Advisory Mode, the DPO Mode percentage includes all the time in which the operator-selected pumps and speeds match the DPO recommendations within a configurable margin of error.
The Specific Energy Plot shows the historic energy consumption for different flow rates and pump combinations. Use the legend to toggle combinations on and off and compare the energy consumption when DPO is in control (Optimizing) versus not (Not Optimizing).
