Secure Connection to the Energy Transition

The main objective of the power generation and distribution industry is ensuring power supply safety and reliability. WAGO products provide the greatest degrees of safety and quality. We have a complete line of products from electrical interconnection technologies to automation solutions.

Operators of ecopower plants fiercely compete for the cheapest kilowatt hour and must pay attention to efficiency and low costs when installing their systems. They are also required to connect systems of a certain size to the control system of the grid operator so that they can be down-regulated remotely as required. That requires telecontrol communication.

Solar Farm Management: Photovoltaic Network-Friendly Control

To enable communication between electricity producers and grid operators, the operators of photovoltaic power plants revert to telecontrol protocols. WAGO Controllers provide a standardized and easy-to-use interface for users based on the IEC 60870-5-101/-103/-104, 61400-25, 61850-7-420 (Server/Client), MODBUS, DNP3 standards. Advantages of WAGO's telecontrol solution:

  • Direct communication between telecontrol system and power inverter or to solar system data logger
  • Separate ETHERNET interfaces permit the creation of parallel networks
  • Cybersecurity: Encryption that follows Europe's most stringent energy and security guidelines per BDEW and BSI
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade
  • Password-protected Web-based management prevents unauthorized users from changing system settings
  • Free function blocks for expanded capabilities, e.g., data loggers and inverters
  • Implementing the respective grid operator's requirements for active power feed-in and reactive power supply
  • cos ϕ or Q/U control (reactive power control) according to the characteristic
  • Integration of external measurement systems from the medium voltage (network analysis devices, short circuit indicators, network and equipment protection) via Modbus TCP/RTU or other fieldbus protocols
  • Recording of low-voltage performance data via 3-phase power measurement module
  • Easy parameterization and configuration via visualization
  • Modular design: Digital, analog and specialty I/O modules can be combined within a node
  • Select from more than 500 different I/O modules

Solar energy fluctuates and must be regulated.

Connection Technology: Safe, Simple Installation

In assembling a photovoltaic system, safe, simple installation is decisive. WAGO enables both: With the comprehensive TOPJOB® S Rail-Mount Terminal Blocks, photovoltaic lines are reliably and permanently connected. Disconnect and fuse terminal blocks with high voltage resistance securely isolate photovoltaic generators from inverters. Additional solutions like blocking diodes round out the offering.

WAGO simplifies installation of solar power plants.

Solar Inverters: More Compact and Durable with WAGO

The inverter is the heart of the photovoltaic system. It converts the direct current from solar modules into an alternating current, which is then fed to the public power grid. The devices have very little loss with an efficiency up to 99%. In other words: Only one hundredth of the DC power is lost during conversion. The durability and performance of an inverter is determined by its electronic and electromechanical components. They must work reliably for many years and ensure high functionality and safety in small spaces. WAGO's high-current PCB terminal blocks meet those requirements.

Wind Park Management: Power Production in Compliance with the Grid

Wind turbines have modern electronic controls. The main controller as the central element is in constant contact with peripheral control elements, such as the wind tracking system and the blade adjustment system. This contact ensures optimal operation in any weather by changing individual system parameters. Proper infeed of the turbines in the power grid requires constant monitoring of the system's grid connection. Grid variables such as voltage, current and frequency are recorded and continuously sent to the plant control system to ensure an immediate response to defined limiting values that have been exceeded. WAGO supports wind farm management and ensures smooth communication with the grid operator, direct marketer and turbine operator. This allows the players delay-free access to the system without delay. The WAGO-I/O-SYSTEM 750 ensures that wind farms can be controlled and monitored fail-safe. Advantages of WAGO's telecontrol solution:

  • Communication via standard telecontrol protocols per IEC 60870-5-101 /-103 /-104, 61400-25, 61850-7-420, MODBUS and DNP3
  • Thanks to numerous I/O modules, the I/O system is ideal in the distribution grid, e.g., for serial communication with external devices or for 3-phase power measurement.
  • Convenient measurement and monitoring of generation or consumption rates (e.g., voltage, reactive power, active power, current, cos φ, frequency and energy flow direction)
  • Controllers available for all common fieldbus systems and ETHERNET standards
  • Separate ETHERNET interfaces permit the creation of parallel networks
  • Programmable via CODESYS per IEC 61131-3
  • Cybersecurity: PFC100/PFC200 Controllers comply with current IT security regulations for grid operators and can be hardened as described in the BDEW white paper.
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade
  • Password-protected Web-based management prevents unauthorized users from changing system settings
  • Function blocks available at no cost
  • OPC/XML client
  • IEC 61400-25 client

Bioenergy: Safe Automation Even in Hazardous Areas

A biogas plant produces biogas by fermenting primarily renewable raw materials or manure. In most cases, the gas is fed directly to local combined heat and power (CHP) plants and then fed into the public power grid. However, biogas can be processed into biomethane just as easily and fed into the natural gas network or converted in remote CHPs for decentralized local heating use. The WAGO-I/O-SYSTEM is used in all areas – whether in the automation of individual processes, in controlling processing plants or in connecting the generation plant to the control system of the grid operator or the supplier of control energy. Advantages of WAGO's telecontrol solution:

  • Communication via telecontrol protocols per IEC 60870-5-101/-103/-104, 61400-25, 61850-7-420, MODBUS and DNP3
  • Thanks to numerous I/O modules, the I/O system is ideal in the distribution grid, e.g., for serial communication with external devices or for 3-phase power measurement.
  • Convenient measurement and monitoring of generation or consumption rates (e.g., voltage, reactive power, active power, current, cos φ, frequency and energy flow direction)
  • Controllers for all prominent fieldbus systems and ETHERNET standards
  • Process signals in Ex zones can be directly connected to the intrinsically safe blue Ex modules from WAGO.
  • Separate ETHERNET interfaces permit the creation of parallel networks.

“The System is Practically Protected against Mismating.”

The requirements on state-of-the-art building installations have changed. As construction times grow shorter, the electricians have less and less time on the jobsite for installation work. Add to this additional tasks like commissioning fire alarm systems or IT installations, which also fall within the scope of their activity.

Therefore, thinking outside the box can show whether it makes sense to use a state-of-the-art connector system. Elektro Schlötel describes its experience with the WINSTA® Pluggable Connection System.

Caution! Bat Crossing

The goals of a wind power operator are to optimize switch-off times and increase yield. Where winged animals rule the skies, it has been necessary to reckon with costly downtimes – but Senvion is showing how to change that. With the help of WAGO, the wind turbine manufacturer offers operators the possibility of reacting even more flexibly to changes, for example: bat conservation.
