SÜC in Upper Franconia is a reliable supplier of mainly energy, gas, water and heating for Coburg and the surrounding area. At the end of 2011 we participated in a trial as part of the project “feed-in management for renewable energy and hydroelectric plants of more than 100 kW” – successfully!

Description

The SÜC personnel were convinced by the overall telecontrol concept with simple configuration, so at the start of 2012 we received the order to supply renewable energy plants. The net-line FW-5 renewable energy systems were delivered fully pre-installed in a wall-mounted housing and, after initial support with commissioning, could be planned independently. Communication was mostly set up with a GPRS link using IEC 60870-5-104, the connection being made to the RESY central control station by means of a net-line FW-50 node.

The SÜC engineers were so impressed by the renewables project that SAE telecontrol technology was also chosen for the planned connection of further transformer stations. The medium-voltage plants can mostly be reached with their own FO cables, so in this case too communication was set up using IEC 60870-5-104. In addition to the monitoring of transformer switches, gas monitoring, transformer temperature, battery signalling etc., in this case the 1.5-pole actuation of two isolator switches is provided by double command, which is realised by means of the net-line FW-5 add-on module DSO-1.

At the start of 2013, SÜC put a new cogeneration unit for heat and power supply with two machines into operation. Previously a net-line FW-50 station in a 19″ rack was chosen for connection using IEC 60870-5-104. In addition to the relatively large I/O capacity with metered value processing and switch actuation with checkback via DSO modules, two Modbus remote connections for cogeneration plant control and a further PLC were realised.
