Energy Monitoring Automation

With the lifestyles of modern world, the demand for energy and accordingly for electricity are increasing everyday. So, it is required that energy producing and distributing processes must be safer and more cost effective. If we don’t exploit the advanced technology we may pay a heavy price for.

For ensuring safer and more cost effective energy production, automation system is a must. Thus, it can be possible to monitor all steps from production to delivering, from distributing to parameter optimizing.


Advantages of Energy Monitoring System

The most significant advantages of an electricity distributing system that controlled and monitored with this system are using the available energy in a way that is most cost effective as well as eliminating the risks in terms of security of life and property. Also the advantages of the system as follows:

  • • Because all energy parameters of electricity distributing system are being controlled constantly energy consumption is under control.
  • • Due to all failure status of instruments within the system can be traced simultaneously from automation system, quick response to the failure is possible.
  • • Automation system that operates according to a certain scenario controls the field equipment error-free, so it is safer than the systems that operated by human drive.
  • • Automation system removes human errors as well as may be operated with fewer personnel. Loading and load shedding processes can be added to scenario operating in system. This ensures minimum energy consumption.
  • • It also extends the service life of instruments within the system. Loading and load shedding processes enable or disable the related points according the loads on these energy production points (transformer/generator) or certain energy consumption points (drawn current/power). Thus, minimum energy consumption is ensured.

Control and Command System

This is the unit that performing desired control scenarios. These unites are used commonly with PLCs (Programmable Logic Controller). The unit collects the required signals of field controlling elements and commands the field components according to program installed.

Digital signals those arriving to PLC system include on/off signals and thermal failure signals of motorized switches, automatic/manual signals and some failure signals.

Signals from current/voltage/power/power factor transducers are analogue signals (4-20 mA, 0-10 VDC etc).

Energy analyzers send parameter information to PLC over communication line. Communication is performed with Modbus protocol commonly over RS-485 platform.

According to these signals coming from the field, PLC system produces digital signals that will command motorized switches. PLC systems’ advantages are as follows:

  • • Eliminates the complexity of relay command circuits and the difficulty of component adding/removing, as well as provides easy replacements/extensions.
  • • Not requires frequent maintaining.
  • • Has a low footprint.
  • • Has a high performance.
  • • Operates in adverse industrial environments (dusty, hot, humidified, noisy etc.)
  • • In case of requiring increased capacity, it can be easily expandable.

System Structure

  • • Control and Command System
  • • Command Sending and Monitoring System
  • • Field Control Equipment

The software used to program the PLCs has ease of use and a large library of function in line with advancements of software developments. This software can be run on PCs. In addition to basic logic and arithmetic functions, there are also custom-developed functions and special control algorithms such as PID. Therefore PLCs are conveniently used in feed back automation systems as well as logic based automation systems.

Apart from the digital modules, there are also high tech modules such as analogue-digital or digital-analogue converter modules, the modules developed for position and speed control, high speed counter modules, modules having special math processor.

PLCs provide exceptionally good solutions via advanced communication protocols and modules for the areas such as remote control and network (connecting multi PLCs together) which are required especially by medium-large scale business.

It consists of computers by which all locations – those being under control of the control and command system – can be monitored and commanded. A special software that running in PC gives the automation system some features such as traceability, centralized commanding and controlling, reporting, etc. This software is called generally as SCADA/HMI ( Supervisory Control and Data Acquisition /Human Machine Interface ). This program is continuously in communication with PLC. All data in the communication between PLC and SCADA/HMI is refreshed approximately each second. In case of computer or SCADA/HMI application is disabled, automation system can continue to work with no error. But due to there is no communication during this period, there can’t be any data or alarm record on computer.

SCADA software’s key features are as follows:

  • • Sending command to field components
  • • Monitoring the status of field components
  • • Monitoring energy parameters and recording onto hard drive
  • • Energy parameter graphics
  • • Tracing the failures
  • • Alarm grouping and management
  • • Warning the operator with sound and graphic animations
  • • Reporting (including the history)
  • • Creating the variance curves of analogue values by time
  • • Extendibility, network connectivity
