Modernization on All Levels

Automation of energy grids has many advantages. The advantages include the possibility of monitoring and remote control. WAGO has the right solutions.

In the first step, grid operators can use WAGO technology to precisely identify where their infrastructure must be modernized. Our controllers can then be used later to automate processes and support load management. In this way, grid capacities can be better utilized – and can reduce the need for new lines.

Intelligent Distribution Substations: Key to the Smart Power Grid

Just like conventional local power stations, the intelligent distribution substation (iONS) connects the medium- and low-voltage grids. Unlike its less advanced counterparts, however, the new substation also records measurement data and allows this data to be read remotely. WAGO is ready to support an iONS with comprehensive automation technology: The PFC200 Controller on the medium-voltage side and the e!DISPLAY on the low-voltage side for visualizing the measurement and control data directly at the iONS itself, as well as complete connection technology. Advantages of WAGO's solution:

  • Versatile: The controllers, which are freely programmable via CODESYS, collect all data from the substation's various systems via digital and analog signals (e.g., via MODBUS RTU or IEC 61850).
  • Multilingual: Our controllers translate the data into supplier-required communication protocols (e.g., IEC 60870-5-101/-104 or IEC 61850) and transmit it to the control center via data line.
  • In the opposite direction, the control center can access the substation's systems (e.g., medium-voltage control cabinet, protective devices, measurement systems from different manufacturers) via the WAGO Controllers.
  • Cybersecurity: The data flow from WAGO Controllers is protected against unauthorized access by encrypting the data using TLS1.2 and by transmitting the data via specially secured connections, such as IPsec or OpenVPN, according to the BDEW White Paper.
  • Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade

Medium Voltage Switchgear: Automate with WAGO

Switchgear in the distribution grid is a central component of a secure power supply. To ensure this, automation of such stations with WAGO Controllers is an excellent solution. Faults can be quickly localized by connecting the short circuit and ground-fault direction indicators and transmitting the information, while automated systems can be remotely controlled. Parts of the power grid can then be quickly restored and the damage radius is minimized. Advantages of WAGO's solution:

  • Grid sections can be switched on again quickly.
  • The service technician can be sent directly to the fault location.
  • Measured values from medium voltage can be continuously transmitted to the control center.
  • Monitoring helps asset management in future grid planning.

Substations: Network Nodes Always in View

Substations are the interface between generation and distribution of renewable energy. In the event of failure, connected generators such as solar and wind farms, can no longer feed into the power grid. Depending on the severity and duration of the interruption, considerable loss of profit or other damage to technical systems may occur. To avoid failures and to eliminate faults in the near term, remotely monitoring and controlling substations in the event of breakdown are essential. WAGO Controllers can handle these tasks safely and reliably. Advantages of WAGO's solution:

  • Precise fault localization
  • Fast reconnection of grid segments
  • The service technician can be sent directly to the fault location.
  • Measured values can be transmitted continuously to the control center.

Gas Supply: Safe Pressure Regulation

A safe gas supply is just as important as a safe power supply. To ensure a safe supply, monitoring and control of gas pressure regulating systems and coupling stations are indispensable. In addition, the gas network is becoming increasingly important for integrated energy. Due to large storage capacities within a gas network, large amounts of energy can be stored. That also makes automation of feed-in stations necessary. Advantages of WAGO's solution:

  • Fast troubleshooting
  • Online measurement
  • PLC functionality allows implementation of complex regulations and control.
  • Support of all current fieldbus systems, such as PROFIBUS DP or Modbus RTU/TCP, permits integration of third-party systems.
  • Telecontrol protocols such as IEC 60870 or DNP 3.0 allow you to connect to the central control system.
  • Intrinsically safe I/O modules permit integration of signals from Ex Zones 0, 1 and 2 into the WAGO-I/O-SYSTEM.
  • Integrated Web visualization allows the display of processes on site or via remote access.

Heat Supply: Always the Right Temperature

Combined heating and power (CHP), along with the associated construction and expansion of remote and local heating networks, is an important component of energy transformation. During implementation, that means that heat coupling and transfer stations must be safely automated. Of course, the customer requires a secure supply in the cold season – failure here would be fatal! Advantages of WAGO's solution:

  • Precise fault localization
  • Fast troubleshooting
  • Online measurement
  • PLC functionality allows implementation of complex regulations and control.
  • Support of all current fieldbus systems, such as PROFIBUS DP or Modbus RTU/TCP, permits integration of third-party systems.
  • Telecontrol protocols such as IEC 60870 or DNP 3.0 allow you to connect to the central control system.
  • Intrinsically safe I/O modules permit integration of signals from Ex Zones 0, 1 and 2 into the WAGO-I/O-SYSTEM.
  • Integrated Web visualization allows the display of processes on site or via remote access.
