Using IEC 61499 to achieve Smart Grid Automation through Interconnected Distribution Reclosers

Martin van der Linde (Sales Engineer – NOJA Power/B.Eng, B.BusMan)

Industrial automation has been around for many years, in the realm of fast local connections controlled within a small network. IEC 61131-3 has been extensively used for logic implementation in PLC, but it is the advent of IEC 61499 and event based logic processing that we have seen a proliferation in usage of IP based distributed control.

With the growing capabilities of IP based communications for pole top switchgear within utilities it seems a natural progression to allow for distributed logic to be executed across a distribution network as a whole, using the current communications medium and framework as the transporter and a VPN for security. This paper explores the new capability of using IEC 61499’s logic design in pole mounted reclosers to create customised distribution automation and smart grid capabilities without the need for master station control. By sharing the hardware requirements across an entire network of recloser controllers, it is possible to create elegant and responsive algorithms to improve network reliability.

Access to IEC 61499 application design and implementation allows for improved integration in IEC 61850 schemes for recloser control. IEC 61499 offers expanded portable configuration options with information links through definable Dynamic Data Type objects available for access by both protocols in a centralised database within a controller. This paper outlines the capabilities and future applications of IEC 61499 in the world of pole mounted reclosers. As Australian utilities look for the best return in their capital equipment, this new implementation allows for the optimisation of switchgear for maximum return and value for distribution network operators.

Integrating renewable energy sources into smart grids using Automatic Circuit Reclosers

By Steven Keeping (Technology Writer)

There is global momentum to diversify electricity generation sources for economic, environmental and security reasons. “Distributed generation” (DG) enables more companies to enter the electricity market stimulating competition, encourages the development of renewable energy (RE) and limits the impact of events such as cyber attacks. However, conventional electricity distribution networks are poorly matched to the needs of DG because they were designed to meet the demands of large generating capacity sited close to population centres.

Single phase earth faults solutions using reclosers to meet the demands of the modern network

By David Dart (R&D Director - NOJA Power)

The advent of the microprocessor protection relay within a recloser controller has allowed the introduction of a significant number of new protection features and functionality. In parallel to these enhancements the recloser switch has transformed into an extremely reliable switch which operates in a significantly faster time based on the use of the current technology of a vacuum interrupter with an optimised magnetic actuator.

The Reality of Providing Energy in Australia: Bushfire Mitigation and the Benefits of Power Quality Monitoring Outside Substations

By Martin van der Linde (Sales Engineer – NOJA Power/B.Eng, B.BusMan)

Abstract: Utilities operating in Australia face many adversaries with regards to power distribution; challenges which would drive most international counterparts to alternative markets. Australian utilities are a much more resilient group, and with modern developments in pole mounted switchgear, the obstacles faced are not quite as insurmountable as they used to be.

Using the smart grid to mitigate the impact of electric vehicles on future electricity demand

By Steven Keeping (Technology Writer)

Abstract: The electric vehicle (EV) has been subject to rapid development by major automakers and modern EVs are capable of completing 85 percent of typical journeys on a single charge. This, together with reductions in the purchase price, is making the EV an increasingly practical alternative to a conventional vehicle leading to significant growth in the size of EV fleets over the next few decades.

Carbon Emission Reductions by the Implementation of a Smart Grid

By Steven Keeping (Technology Writer)

Abstract: A smart grid – a computerised electricity transmission and distribution network incorporating monitoring, reconfiguration and real time feedback – promises to revolutionise energy delivery by lowering costs, minimising outage frequency and duration, and simplifying the interfacing of renewable energy sources to the system.

Only Smart Reclosers Build Smart Grids

By Neil O'Sullivan (Managing Director) / Bruno Kimura (Brazil Managing Director)

Abstract: Smart Grid is on the agenda of almost every utility in the world today. A true Smart Grid starts with the automation of utilities distribution networks and a key building block for the automation of distribution networks is reclosers. What do reclosers need to provide this building block? This paper attempts to summarise the solution.

DNP3 Security: Challenges and Solutions

By Alan Scott (R&D Software Development Manager)

Abstract: SCADA networks have historically been designed to optimize efficiency and functionality, without consideration of cyber-security issues. Increasing inter-connectedness of networks and regulatory oversight has now elevated cyber-security to be a mandatory consideration for many network operators.

Application of Advances in Magnetic Actuator, Vacuum Interrupter and Microprocessor Technology to Improve Network Performance Through Automation and Better Protection Grading of Auto Reclosers

By Neil O'Sullivan (Managing Director)

Abstract: Today's electricity utilities are challenged with achieving greater performance and reliability levels than ever before, generally with fewer resources available to them. Use of modern auto reclosers with Intelligent Electronic Device (IED) controllers is one of the most effective tools available to today's utility engineer to increase overhead network performance.
