Flexibility is an essential criterion for operation of a transformer station. While conventional, non-controllable transformers experience problems, the WAGO Application Voltage Regulating Distribution Transformer changes the transformation ratio during operation, enabling increased solar power feed-in, for example, without increasing the mains voltage. That alone makes this add-on application for the WAGO Application Grid Gateway an economical, future-proof solution for dynamic voltage value adjustment between the medium- and low-voltage grids. It conserves network coordination resources and enables efficient network expansion. A Step-by-Step Explanation WAGO Application Voltage Regulating Distribution Transformer can be commissioned quickly through simple parameterization. The voltage regulating distribution transformer (VRDT) is coupled through telecontrol technology. The application optimizes the controller behavior. Control parameters can be set and monitored conveniently via Web visualization. Acquisition via IEC 60870-5-104 Telecontrol Protocol and transmission to the tap changer The MR ECOTAP tap changer of the VRDT is controlled via Modbus RTU. Key Benefits: Flexible connection to the control system via IEC 60870 Various control modes: Fixed setpoint or setpoint calculated as a function of the active power Forward all messages from the rONT to another system via Modbus, IEC 60870 or MQTT Easily parameterizable software that can be expanded at any time with flexible hardware that meets critical infrastructure requirements
