Processes ========= Maintenance of Temperature and Start-up --------------------------------------- still to be written. Incoming flows -------------- still to be written. Outgoing flows -------------- still to be written. Process Schedules ----------------- For each process its schedule may be defined in one of the following ways: Simple Schedule ~~~~~~~~~~~~~~~ With only four parameters it is possible to define the times of activity of a process. The effective hours of operation per day, the number of cycles per day, the duration of each cycle and the days of operation per year ar these parameters. As the first three are actually redundant, it is enough to enter two of them. .. image:: ../images/screenshot_simple_schedules.png | Detailed schedule ~~~~~~~~~~~~~~~~~ In a much more detailed fashion, the :ref:`detailed schedule ` offers the definition of running times per week day and these weekly profiles may again be choosen for freely choosen periods within the year. Choose the `Detailed schedule` checkbox and define a detailed schedule. Fit to Data (EINSTEIN *plus* only): ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Process schedules can be obtained automatically by fitting to monitoring data. Choose the `Fit Schedule to Data` checkbox and define an appropriate set of :ref:`monitoring data `. Selection of schedule type ~~~~~~~~~~~~~~~~~~~~~~~~~~ To define a schedule for a process it first must be selected from the `Process list` on tab `Process data` in the `Process data` section of EINSTEIN. .. image:: ../images/TimeSchedules_1.png :scale: 70% Process Schedule Parameters ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Additional global parameters for process scheduling are specified on the tab `Operation` in the `Process data` section of EINSTEIN. There are three global parameters for the schedule of a process: #. `Startup` time specifies the duration of the process startup phase. #. `Inflow` time specifies the duration of the process charging phase. #. `Outflow` time specifies the duration of the process discharging phase. +------------------------+----------------------------------------------+ | | Process type | + +----------------------------+-----------------+ | Phase :math:`\Delta t` | batch | continuous | +========================+============================+=================+ | Operation | :math:`[t_0,T]` | +------------------------+----------------------------------------------+ | Startup | :math:`[t_0,t_0+\Delta t]` | +------------------------+----------------------------+-----------------+ | Inflow | :math:`[t_0,t_0+\Delta t]` | n.a. | +------------------------+----------------------------+-----------------+ | Outflow | :math:`[T,T+\Delta t]` | n.a. | +------------------------+----------------------------+-----------------+ .. image:: ../images/process-times.png :scale: 33 %
