Grid Automation Software Simplifies Enhanced Network Implementations

Nov. 16, 2015
PC-based software uses IEC 61499 Function Blocks to build and deploy control and automation applications for single or groups of ACRs.

NOJA Power has introduced its Smart Grid Automation software, a PC-based software suite that enables engineers to develop, test and debug advanced functionality for NOJA Power’s OSM series Automatic Circuit Reclosers.

SGA software significantly increases the flexibility of the ACRs simplifying the implementation of smart grids. Using the PC-based software, engineers can intuitively develop control and automation applications via an easy-to-use interface. Applications can then be uploaded to NOJA Power’s RC10 controller for the OSM series ACR or distributed to group of controllers for simulation and debugging before field implementation.

The SGA software includes FBs created by NOJA Power that read and write data to the RC10 controller. IEC 61499 also defines a library of FBs for arithmetic functions, conversions and events among others. The libraries also include FBs for exchange of information between Intelligent Electronic Devices (IED) such as OSM series ACRs. This interaction between IEDs is fundamental to the operation of smart grids.

“Because NOJA Power’s auto-reclosers are increasingly being deployed in smart grid implementations we constantly strive to enhance the devices’ flexibility,” says Neil O’Sullivan, NOJA Power’s Managing Director. “SGA software is a significant development in this direction.

“With this software, utilities are now able to develop applications for auto-reclosers that previously weren’t possible. Combined with the software’s ability to distribute the applications across groups of auto-reclosers, utilities can easily establish ‘smart’ interactions between devices considerably enhancing the capability and flexibility of distribution networks.”

SGA software operates in conjunction with NOJA Power’s Relay 1.14 firmware. The firmware supports the RC10 controller used to control and monitor the OSM series ACR.

NOJA Power’s OSM series ACRs are fundamental elements of smart grids and provide a comprehensive suite of automation features. The units perform voltage measurement on all six bushings, current measurement on all three phases, bidirectional protection and extensive power quality and data logging capability. The OSM series has been fully type-tested by independent laboratory KEMA in the Netherlands to ensure long life and reliability under the harshest environmental conditions. Since their introduction, the OSM series ACRs have been installed by utilities in over 84 countries around the world.

The RC10 is a supervisory control and data acquisition (SCADA)-ready controller that provides a directional overcurrent, earth fault and sensitive earth fault relay, auto reclosing relay, instantaneous metering, event log, demand logger and remote terminal unit (RTU) for remote control in a single package.
