Plant Simulation with energy simulation
 Energy simulation is a core
function of Plant Simulation
version 11.
 The same energy dialog is
available in the Plant
Simulation building blocks

Setup
 Using energy simulation in Plant
Simulation is very easy.
 Set energy simulation to active.
 Insert the power input for Working, Setup,
Operational etc. in kW.
 You can (but do not have to) define times
to change from one energy state to the
next energy state.

Energy States
Working: A part is on the machine and it's being
worked on
Operational: All Engines are running, but the machine is not
working – e.g. because it‘s empty
Standby: Electronic is ready but main engines are switched off;
e.g. Standby is a result of the pausing time
Off: Lowest status of energy consumption
Failed: Correlates with the
failure status of the resource
Setting up: Correlates with the
setup behavior of the
resource.

Transition times
 Change energy level:
Off
 Transition times are
defined between:
 Off, Operational and
Standby
 Working, Setup and
Failed are statuses
resulting from the
material flow.
Operational

Standby

State transition
 The energy simulation
feature in Plant
Simulation is simple
and easy to use. The
behavior for pausing
times and unplanned
times in the shift model
are already predefined
and can be selected
from a pull-down menu.

State transition
 „Why switch machines to
Standby or completely Off?”
 Most modern machines allow users
to easily switch off the main engine
and go into a predefined standby or
off mode.
 This feature is seldom used as many
companies do not know the savings
potential.
 The state transition used in the class element of a machine enables users to
calculate the result with one click.
 In the example shown here, changing the machine status during breaks and
during nonproductive night time to Standby saves 6% and to Off saves
12% of the total energy consumption!

Don‘t be afraid…
… to lower production to save
energy by turning off machines.
Modern control units
(e.g. Siemens S7 300 /400 using the PROFIenergy
Protocol)
 Enable users to program a „wake
up time“
 The machine changes to the
previous status before the break or
to Standby when the Off shift time
is over
 This action is predefined in Plant
Simulation with the „Power up
early“ function

Simtalk
 The energy simulation feature can
be addressed using Simtalk.
 To get an overview, mark the
relevant resource and press „F8“ to
visualize all attributes.
 To restrict the table only to the
energy-relevant attributes, click on
the „power flash“

Working with energy simulation
To change a machine’s status to
„Off“ when the machine in front is
empty:
 Change the EnergyTargetState to
„Off“
 Plant Simulation automatically uses
the defined time to turn the machine
off
 Vice Versa
 To start the machine early enough to
assure it‘s operational when a part
enters, set EnergyTargetStatus to
„Operational“

Charts
The Plant Simulation Statistic Wizard
 Is predefined for Energy analysis
 Sorting e.g. by „Operational” points out
which resource has a high potential to
save energy without reducing
productivity by changing the state
actively to „Standby”

Save Energy
 Built-in conveyor lines function

Save energy
 Built-in method to save energy on
accumulating conveyors.
 If the conveyor is accumulating, and all parts
have accumulated and no new part enters,
the conveyor stops to save energy (and
reduce belt friction).
 In this small example the energy
consumption is reduced from 72kWh to
25.6kWh
 64% energy savings with one click!

Summary
 Energy consumption will be a major differentiator for or against a line
builder
 Plant Simulation version 11 offers an OTS toolset to
 Model
 Analyze
 Optimize
 Manage energy consumption in complex dynamic production
environments
