• For line builder

• For any production facility


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


License

The Plant Simulation Energy

Simulation is available in all license

configurations

Professional, Standard

Application, Runtime, Viewer

Education, Student

without additional licenses or fee.


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

Off: Lowest status of energy consumption

Standby: Electronic is ready but main engines are switched off;

e.g. Standby is a result of the pausing time

Failed: Correlates with the

failure status of the resource

Operational: All Engines are running, but the machine is not

working – e.g. because it‘s empty

Setting up: Correlates with the

setup behavior of the

resource.

Working: A part is on the machine and it's being

worked on


Transition times

Off

StandbyOperational

Change energy level:

Transition times are

defined between:

Off, Operational and

Standby

Working, Setup and

Failed are statuses

resulting from the

material flow.


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!


… 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

Don‘t be afraid…


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”


Energy Analyzer

As a new function in Tecnomatix Plant Simulation version 11, we

are proud to announce the Energy Analyzer, patent pending; U.S.

Patent App’l Pub. No. 2013/001863.


The unique Energy Analyzer

Plant Simulation version 11 offers a unique

Energy Analyzer

We are proud to announce the Energy

Analyzer, patent pending; U.S. Patent App’l

Pub. No. 2013/001863.


Plotter

Visualize peak

energy

consumers


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
