Electrical switchgear engineers NOJA Power has announced support for IEC 61850 on its OSM series automatic circuit reclosers (ACR). A full suite of international standards-based communication protocols, IEC 61850 enables fast, reliable communication between the company’s ACRs and Intelligent Electronic Devices (IED) from other manufacturers used in electricity distribution systems.
IEC 61850 standards specify the use of a set of established protocols, including Generic Object-Oriented System Event (GOOSE), which is used for high-speed sharing of process coordination information across Ethernet networks linking IEDs, regardless of the equipment’s manufacturer. GOOSE messaging compensates for network variability while protecting data integrity and can be transported over technologies such as WiMax for communication with IEDs beyond a substation.
NOJA Power's OSM series of medium-voltage 15, 27 and 38 kV ACRs already supports SCADA communication between devices and control centres using the IEEE 1815 (DNP3) and IEC 60870-5-101/-104 protocols over serial- or Ethernet-communication channels. Additionally, NOJA Power supports direct communication between ACRs for automation coordination using a proprietary protocol.
NOJA Power’s support for IEC 61850 via an upgraded firmware platform due for release later this year will complete the suite of communication protocols used in modern networks.
Developed by the International Electrotechnical Commission (IEC) and the European- and North American-equipment manufacturers as the basis for communication and control of IEDs and other Distribution Automation (DA) for modern networks, the IEC 61850 family of standards facilitates interoperability, which is important in the realisation of smart grids and promises to overcome the challenges of integration and testing between systems comprising of equipment from different manufacturers.
NOJA Power CEO Neil O’Sullivan explains that their ACRs are an essential component of smart grids and their customers increasingly expect the company to support the standard to ensure interoperability between NOJA Power products and those from other IED manufacturers.
