Telecontrol Connection for Customer Transfer Stations

Whether power generation plants, storage systems or load customers: When it comes to the medium-voltage connection, customer transfer stations need to be linked through telecontrol technology. Even though the TCRs (technical connection rules) vary from one grid operator to another, in about three quarters of German medium-voltage grid territories, WAGO’s Customer Substation software application lets you establish the connection in just ten minutes, because the application offers standardized, pre-configured software for various grid territories.

In addition, WAGO can offer solutions for your company’s specific level of programming expertise and staffing according to your specific needs, whether for system integration, switchgear manufacturing or station building.

Advantages:

  • Industry-proven telecontrol technology hardware; hardened per BDEW white paper
  • Easy software parameterization with no programming per VDE-AR-N 4110
  • Complete solution consisting of hardware and software in a ready-made control cabinet

What is a Telecontrol Connection for?

Decentralized generation systems and customer transfer stations that link directly to a grid operator’s medium-voltage network need to be connected via telecontrol technology. This is necessary for two reasons above all:

  1. For grid operation:
    This requires transmitting signals, data and/or messages, such as position reports on the medium-voltage switchgear, warning and error messages about the system and the equipment to protect the grid, feedback about system availability, measured operational values at the grid connection point and information about the control of the supply of reactive power.
  2. For feed-in management per §9 of the German Renewable Energies Act EEG:
    Here the telecontrol connection is used with generation plants and storage systems in order to transfer the setpoints for reactive power feed-in (including feedback) and the measured values for recording the actual output.

The implementation of both grid operation and feed-in management needs to be combined into one telecontrol device. Through so-called grid guidelines, specifications and technical connection rules (TCRs), grid operators set their specific requirements on the telecontrol connection of customer transfer stations in medium-voltage grids.

For medium voltage, the distribution grid operator provides a gateway that makes the required signals available at a communication interface, and these gateways may differ. For example, Westnetz provides an IP-based interface (IEC 60870-15-104), while a serial protocol (IEC 60870-5-101) is provided for the telecontrol connection to e.on’s medium-voltage grids.

These interfaces then represent the property boundary between the grid operator and customer. On the customer side, corresponding telecontrol technology must be deployed to provide the required signals.

Telecontrol Connection – Easy, Scalable and Flexible

WAGO telecontrol technology is proven in practice in the energy industry – especially in substations, where it serves as a data collection point and interface coordinator. In addition to a wide variety of other protocols, it includes the IEC 60870-5-101, -103, -104 and Modbus® communication protocols required for the telecontrol connection of energy generation plants and the necessary cybersecurity packages.

The communication libraries for the telecontrol connection of generation systems, most of which are free of charge, have already been adapted to the relevant specifications or signals of the grid operators’ technical connection rules (TCRs) and are easy to parameterize on the software side in combination with WAGO telecontrol technology.

WAGO offers a plug-and-play solution as a full-service package consisting of pre-wired control cabinets tailored to the relevant grid connection specifications, including simple sample programs for parameterization.

The WAGO Solution at a Glance:

  • No-cost communication libraries for the telecontrol technology connection of decentral generation plants, storage and load customers in the medium-voltage networks of e.on, Westnetz, EnBW and EWE
  • Plug and play: With complete solutions customized to the respective specifications of the specific network operator; they consist of a pre-wired control cabinet with corresponding hardware and easy-to-parameterize example programs.
  • Efficient support and service during hardware procurement as well as the experience and knowledge to also provide support to deviating network areas in connecting the network to medium voltage per VDE AR N 4110
