Fault Current Limiters for increased capacity in electricity networks and reliable connection of distributed generation and renewable energy sources

GridON is a leading provider of Fault Current Limiting solutions for increased capacity in electricity networks and cost-effective connection of distributed generation and renewable energy sources. GridON provides fault mitigation solutions for network utility operators, independent power producers, and industrial customers.

Load growth, connection of distributed generation and increasing interconnection of networks all lead to higher short circuit surge currents, often exceeding switchgear ratings. Cascading fault currents result in supply disruptions, equipment damage and severe power outages. Grid operators are forced to invest hundreds of millions of dollars in upgrading sub-station equipment like switchgear, overhead lines, bus-sections and transformers - in order to prevent catastrophic consequences. Conventional solutions such as grid segmentation and costly upgrades negatively impact the power quality, stability and reliability of supply.

The proliferation of Distributed Generation (DG) is increasing fault levels beyond equipment rating, and has been challenging both network operators and Independent Power Producers (IPPs). The fault current contribution from new generators needs to be reduced to near zero in order to enable such new connections. Consequently, connection requests are often rejected by the grid operators due to lack of fault current headroom in their networks. In some cases, connections are made possible through conventional resource-intensive and often disruptive network reinforcement, with substantial cost and delays to the IPPs. This leaves available generation capacity underutilized, thus inhibiting energy source diversification and improvements in network capacity.

Energy intensive industries - such as chemical processing, automotive, steel, cement, mining, oil & gas, water desalination and data centers - rely on uninterrupted operation and are extremely sensitive to electricity disruptions, which may lead to severe business impact and financial losses.

GridON is offering grid operators, IPPs and industrial customers cost-effective fault current limiting solutions which enable network meshing and cost-effective connection of distributed generation and intermittent renewable energy sources; while improving network stability and energy efficiency. The product accelerates connection of new generation sources and enables secure supply of power to utility networks and industrial plants. Network planners are now able to quickly design in the product with minimal changes in the network. While eliminating costly network upgrades and early retirement of fit-for-use equipment, GridON's products can save between tens and hundreds of millions of dollars in industrial and utility networks, respectively.

GridON offers two product lines covering all market segments: (a) a pre-saturated core Fault Current Limiter (FCL) for medium-to-high voltage distribution and transmission networks; and (b) a solid-state Fault Current Limiting Interrupter (FCLi) for low-to-medium voltage DG connection and industrial networks. These cost-effective solutions significantly reduce capital expenditure and time consuming labor, required for network upgrades.

Being scalable to very high voltage and power ratings, the commercial FCL product is well-suited for distribution and transmission networks. GridON’s FCLs have been operating flawlessly in live networks since early 2013 – proving extremely reliable, easy to operate and maintain, and very effective in limiting numerous faults. GridON’s FCL is based on combining industry-standard, proven transformer technology with unique and proprietary concept of electromagnetic flux alteration on a saturated iron core. This fail-safe system responds instantaneously to faults, suppresses fault current for its entire duration, and recovers immediately following fault clearance – being always ready for consecutive faults. The FCL is the first commercially available pre-saturated fault current limiter currently available in the market. GridON has partnered with Australian based Wilson Transformer Company, a shareholder and manufacturing partner, to offer a state-of-the-art portfolio of FCL products to the market.

GridON's cost-effective, compact FCLi limits and interrupts excessive fault current and mitigates arc-flash in low-to-medium voltage networks. Designed with relatively small footprint and low price tag, the FCLi is a perfect solution for grid operators, independent power producers and industrial customers. This solid-state based product limits excessive fault current in the network before it rises to high level, and acts to interrupt it before the first current peak. By controlling excessive fault currents, the FCLi enables fast and cost-effective connection of IPPs and dispersed generators. It also allows increased power capacity in industrial plants, and sale of excess generation capacity to the grid. Return on investment in an FCLi is expected within one year.

These cost-effective solutions significantly reduce capital expenditure and time consuming labor, required for conventional network upgrades.

GridON has been an active member of the IEEE/PES workgroup PC37.302 which issued an official guideline for fault current limiting technologies. GridON won prestigious awards including the 2013 UK Energy Innovation Award for the Best Energy Network Improvement, the 2012 European ACES Smart Grid and the 2011 GE ecomagination “Powering the Grid” award.
