Overview

The increase in power prices over the past few years has led to
higher operating costs and can pose a threat to a company's
competitiveness.

The goal of the Power Management System is to optimize
operating costs and increase plant availability.

The system is based on service-proven industrial technology
and meets special demands of quality and availability. As an
element of Totally Integrated Automation and Totally Integrated
Power, the power management system guarantees the consistency
of products and systems, the use of standard components, a uniform
operating philosophy and a reduced amount of engineering
work.

In other words: With Power Management you can make full use
of all the potential for optimization provided by a consistent
power management solution.

Components for the Power Management System

The power management system comprises both hardware
components and software components.

The hardware components are:

• Multifunction power meters for measuring the power data

• Communication-capable switching and protection devices

• SIMOCODE pro motor management system

• E-counters

• Protective devices such as SIPROTEC

The software components are:

• SIMATIC powercontrol power management software

• SIMATIC powercost

Various power distribution products can be integrated in the
Power Management System. They include hardware and software
components such as the SIMATIC powercontrol power management
software, multifunction measuring instruments, SENTRON
communication-capable circuit breakers, the SIMOCODE pro
motor management system, E-counters or protective devices
such as SIPROTEC.

Apart from performing their initial function of protecting the
power distribution, modern communication-capable switching and
protecting devices are also able to deliver additional information
such as device status, setting parameters and measured values.

Non-communication-capable field devices are connected to the
PROFIBUS through I/O modules such as the ET200. The related
power data are thus made available with the help of pulse inputs
or converters and the device status is recorded through digital
I/Os.

Recording the consumption data of other types of energy is
possible using suitable measuring equipment through the
central or distributed peripherals of the SIMATIC S7.

Software components

SIMATIC powercontrol

SIMATIC powercontrol throws light on power flows - from infeed
through distribution to loads - in order to permanently reduce the
operating costs of power distribution systems:

• Central overview of all the power flows in a power distribution

system

• Detailed overview of all switch states

• Knowledge of the demand profile from the continuous acquisition

of power data

• Detailed consumption information and load-related assignment

of amounts of power and costs

• Display and archiving of the consumption values, e.g. as

15-minute mean values

• Combination of different power types in one tool

SIMATIC powercost

SIMATIC powercost is the cost center module of SIMATIC
powercontrol for automatic and load-related assignment of
power and costs to individual company units:

• Low-cost, secure, and load-related energy assignment

• Flexible and transparent cost determination

• Easy and open display of results

Management System can be found in Chapter 18 and on the
