Modular Power Analyzers in the Collection of Energy Data
Keeping energy consumption to a minimum in optimal operating and production conditions is the main goal of energy efficiency and energy management projects. Reducing energy costs in operation and production will reduce costs, which will increase the chances of competition for businesses. Modular power analyzers in collecting energy data efficiency standards and regulations are of great importance in energy efficiency studies.
ISO 50001 Energy Management standard; It draws a framework for energy studies, where energy is used, where and how much energy is used and energy saving potential is determined. To achieve this, there is a need for continuous information on energy use. In order to transfer the electrical and physical measurement values to be collected from the field to the automation system without any problems, it is necessary to select the appropriate PLC configuration and apply it to the system. Another important point is the implementation of the designed system with optimum cost. WAGO designs systems that are both cost-effective and reliable and provide continuous data flow, deploy them and constantly updates this vision with its innovative products.
Three different types of modular power analyzers, offered for sale with WAGO’s product codes 750 – 493/494/495; are innovative energy analyzers that can be installed modularly next to a WAGO PLC unit, with current transformer and voltage leads connected directly on it.
These power analyzers are connected directly to the PLC node, and can directly transfer data to the PLC processor by bus communication in the modular structure. In this way, a second communication line between external energy analyzers and PLC is not required and data losses are eliminated. It is used independently from the fieldbus since it works directly integrated with WAGO I/O SYSTEM. In other words, in the process, Profinet, Modbus, Profibus or Devicenet can be IEC 61850 or IEC60870-5 in energy, natural gas and water applications. In building applications, LON, BACnet, KNX or Ethernet can be used.
ON THE WAGO PLC PROGRAMMING INTERFACE, THE CUSTOMIZED READY FUNCTION BLOCKS FOR THIS MODULES REDUCE THE ENGINEERING COSTS. EVERYTHING IS PRESENTED IN THE WAGO LIBRARY AND ALL ENGINEERING DESIGN AND PROCESS HAS BEEN DISCONNECTED.
Scope of Application
- Energy consumption measurement of machinery and plants.
- Increasing transparency in energy use.
- Identification of specific actions for energy saving.
- Determination of compliance with legal restrictions for use in solar farms and wind farms.
- This analysis for determining harmonics requires complex calculations. With 750-494 / 495 modules, 3-phase current and voltage harmonics are calculated simultaneously.
- All parametric settings are made directly with the PLC programming interface, and all of the measurement values are directly in the use of the PLC programmer.
- These modular analyzers are preferred in applications where there are many consumption points because they can perform both three-phase and single-phase measurement capabilities and harmonic analysis.
- The operation with these analyzers both completely eliminates the main PLC load and the problems caused by the reading times, communication problems and cabling caused by Modbus communication are eliminated in the standard analyzers mounted on the field. A smaller PLC can carry out all the tasks of a much more expensive PLC.
In order to transfer the electrical and physical measurement values to be collected from the field to the automation system without any problems, it is necessary to select the appropriate PLC configuration and apply it to the system. Another important point is the implementation of the designed system with optimum cost. WAGO integrates the hardware solution with software with system design and reporting in accordance with ISO 50001, especially for energy saving, consumption monitoring and optimization. Thus, it designs systems that are both cost-effective and reliable and provide continuous data flow, deploys them and constantly updates this vision with its innovative products. Collecting energy data is one of the most important stages of energy automation.
