Bausch Datacom will be present at European Utility Week 2014 – 4 till 6 November, Amsterdam – Hall 1 Booth A76.

EUWBausch Datacom presents a portfolio of RTU’s, GPRS modems, EV charging infrastructure electronics and is participating in the engineering of innovative sensor technologies for electricity substations for the years to come. The company focuses on 4 major (communication) aspects of the electricity grid: IEC 60870-5-104 SCADA communication, external meter reading communication, EV charging infrastructures and ‘Active Substation ‘ technology. www.bauschdatacom.be

Measuring: ‘Active Substations’, cost effective retrofit of innovative sensors for mid-voltage infrastructures and substations.

European electricity distributors are compelled to comply with European standard EN 50160 and in many cases offer additional service level agreements to their customers in order to reduce voltage fluctuation of the required standard (norm) consumption. Lifetime and physical boundaries of infrastructure and short circuit events make it necessary to (tele)monitor mid-voltage substations. The WAN communication of these parameters is in many cases through GPRS/3G TCP/IP communication to a SCADA master set up. The ‘Active Substation’ concept is generating more and more support and investments. The idea of a ‘Smart Substation’ monitoring Power Quality, directional fault passage, partial discharge of transformers information etc. and communicating this information online (GPRS or 3G) to a SCADA back office is clearly becoming more and more important. Also the usage of generally accepted communication protocols (IEC 60870-5-104) is more and more part of a proven strategy.

Lifetime and physical boundaries of infrastructure and short circuit events make it necessary to (tele)monitor mid-voltage electricity cabinets.

Bausch Datacom is one of the key partners of Eandis and KU Leuven/Energyville  in the further development of a patented mid-voltage sensor technology. The development is supported by KIC InnoEnergy.

The technology is capable of measuring and monitoring voltage parameters at medium voltage without opening the XLPE cable to the core. The technology will result in compact and low cost sensor solutions that will be easily retrofitted in the field. The aim is to offer products in 2016/2017 worldwide.

Communicating: ‘Modem grouping’ and IEC-60870-5-104 slave RTU’s and modems.
Bausch Datacom specializes in modems and RTU hardware with integrated IEC 60870-5-104 protocol for SCADA applications. These products communicate as ‘slave’ hardware over integrated GPRS (3G). Aim is to offer cost effective hardware to communicate with master IEC 60870-5-104 host systems such as ABB SPIDER, Clearscada and other SCADA systems. Electricity distribution companies such as Infrax (Belgium), SIG Geneva (Switzerland) f.i. use the DinBox RTU SL to monitor their network.

On the other hand Bausch Datacom continues to develop its external modems for meter reading applications and also Praxis, a Modem Management System. Praxis enables the modems to be grouped and monitored remotely. Firmware updates, RSSI monitoring, changing from GSM to GPRS and vice versa, it is all possible.

Case studies
Case 1: Infrax (Belgium): “In the Lommel 10 kV distribution network we want to guard and monitor each 10/0.4kV transformer substation. The 10/0.4kV distribution transformer is guarded by measuring voltages, active power, reactive power and currents. Also negative power (P,Q) must be measured because the renewable energy produced by PV solar panels is transported decentralized, in the opposite direction. For this purpose we use an A2000 Gossen-Metrawatt Multifunctional Power Meter and a Bausch DinBox RTU SL. The Power Monitoring Device is measuring the 4 important parameters of the distribution network (U,I,P,Q) and is connected to the DinBox RTU SL over RS-485 Modbus RTU. The DinBox RTU SL will communicate the information over GPRS to the SCADA-DMS system SPIDER (ABB) of Infrax .”

Case 2: For ‘Smart substation monitoring’ a typical setup is described hereunder: Low and midvoltage parameters are monitored, the information is processed and sent to the SCADA Master system using the IEC 60-870-5-104 protocol over GPRS or 3G. A ‘SuperRTU’ capable of collecting and processing both the data of the LV and MV parameters and sending this to the SCADA. could be used for this scenario. This ‘SuperRTU’ is already in prototype phase and could be a very effective tool for the monitoring of substations.
