ELECRAMA is the world’s largest electrical T&D exhibition held biennially in Mumbai, India since 1990. From the beginnings in 1990 with 283 exhibitors, it has grown significantly. During the last edition two years ago, ELECRAMA hosted 1,243 exhibitors from many different countries.

During this exhibition, LIOS proudly presented the new EN.SURE generation of Distributed Temperature Sensing (DTS) systems and Real Time Thermal Rating (RTTR) solutions for ampacity predictions of energy transmission:

• Highly reliable DTS systems with a range of up to 40 km for single mode fibers and multi mode fibers in single end configuration.

With a solid installed base in India for temperature monitoring of (Extra) High Voltage power cables, LIOS and PCI LTD are the preferred solution provider for utilities.

LIOS’ multi mode and single mode Distributed Temperature Sensing systems offer real time temperature surveillance of this important link to avoid overheating of the submarine conductors and subsequently power outage.

Opsens Inc. (“Opsens”) (TSXV: OPS) is pleased to announce signing of a long-term agreement with Lios Technology GmbH (“Lios”) to provide an integrated solution to measure pressure and temperature in SAGD wells.

With this agreement, Opsens’ OPP-W high-temperature optical pressure and temperature sensor will be combined to LIOS’ high-temperature Distributed Temperature Sensing System (“DTS”) to provide a complete profile to optimize and improve SAGD well management. Combining the two complementary well monitoring technologies incorporating temperature and pressure measurements from two leading suppliers of fiber optic based measurement systems contributed to the successful installation of their High Temperature solution into already several projects in Canada.

The benefit of this alliance is to combine complementary well surveillance solutions and apply the advanced concept on Steam Assisted Gravity Drainage (SAGD) and other Enhanced Oil and Gas Recovery wells. This concept of effective applied synergy expands the scope of measurements by offering pressure as well as distributed temperature (DTS) measurements. With this integrated solution, the customer will have the ability to monitor pressure and temperature at the toe of the horizontal well, in addition to temperature along the entire wellbore with sub-meter spatial resolution.  The result will be a comprehensive wellbore profile which can be used for enhanced optimization and improved well management.

“We see considerable potential for LIOS distributed sensing products in the Western Canadian Sedimentary Basin and we look forward to exploring further possibilities that this partnership between LIOS and Opsens can offer,” says Gaetan Duplain, Opsens Vice President Oil and Gas.

Thomas Oldemeyer, Chief Executive Officer of LIOS Technology commented, “We’re exceptionally pleased to offer our products through Opsens Solutions. This partnership allows LIOS to operate in extreme harsh downhole environment and benefit of Opsens Solutions expertise in installation and completion of downhole instrumentation”.

In thermal recovery processes, Opsens’ OPP-W fiber optic sensor system provides oil sands producers with reliable real-time downhole pressure and temperature information about their SAGD wells during operation. The ability to accurately control bottomhole pressure at high temperatures for artificial lift systems such as electrical submersible pumps allows SAGD operators to improve steam/oil ratios and to reduce operating and lifting costs.  For multiple well operations, this can provide millions of dollars in savings by reducing water treatment costs, optimizing natural gas consumption as it pertains to steam generation and enhancing the run time of artificial lift systems. Opsens Solutions’ also has an ongoing commitment to the development of reservoir surveillance solutions and for CO2-EOR, geological storage of CO2, and unconventional gas projects.

Industrial Application: High Voltage Power Cable Monitoring – Smartgrid

		Beijing: Long Distance Cable Temperature Monitoring System for the Olympic City 2008 Beijing This project was the premiere of a successful cooperation between Brugg Cables and LIOS Technology. Both partners are currently developing further projects for power cable monitoring even with integrated dynamic rating systems (RTTR).

		Burbo Offshore Windfarm – Distributed Temperature Monitoring of Long Distance Submarine Cables Distributed temperature sensing (DTS) of long distance power cables is shown to provide valuable information for cable design optimisation and proper operation of wind farms. The long range sensing is enabled by using the Raman-OFDR (optical frequency domain reflectometry) technology in single-mode fibres. Raman-OFDR uses a modulated continuous wave laser for detection. The low peak power minimizes stimulated Raman-scattering in single-mode fibres making accurate temperature sensing over long distances feasible.

		Graz: Reliable Energy Supply for Graz, Austria The new cable installation is one of the city’s main transmission lines and is heavily loaded. In order to optimize the transmission performance and to guarantee its secure reliability, the cable installation has been equipped with large scale cross-bonding systems at its sheath. In addition, by the help of the LIOS temperature monitoring system (DTS), the level of backup capacity can be assessed.

Real-Time Cable Thermal Rating (RTTR) went on-line at a tunnel near Stockholm, Sweden In October 2006 the commissioning of the integrated condition monitoring system (CMS) for real-time monitoring of cables was successfully completed. Together with a Distributed Temperature Sensor (DTS) a parallel run of cables installed in a tunnel near Stockholm (Sweden) is being continuously rated by RTTR.

‘Powering Europe’, launched today at the GRIDS 2010 conference and exhibition in Berlin organised by EWEA, argues there are no major technical barriers – but there are major economic benefits – to integrating large amounts of fuel- and pollution-free wind energy into Europe’s electricity grid.
The new report identifies infrastructure and markets as the two key barriers to hugely increasing the amount of wind power in Europe’s electricity supply.

In order to deliver the onshore and offshore wind energy from where it is produced to where it will be consumed, Europe needs:
•    extended, upgraded and better connected grids,
•    fair and effective competition in a truly internal European market in electricity.
The economic benefits of creating a single market in electricity and improve the infrastructure are substantial, according to the new EWEA report. The benefits of a better interconnected grid include a €1,500 million yearly reduction in total operational costs of power generation due to increased availability of all generation capacity.
The benefit of integrating 265 Gigawatt (GW) of wind into Europe’s grids by 2020 – compared to no further growth in wind power capacity – would be a saving of €41.7bn per year in the cost of electricity. This is a ‘merit order’ effect of €11 for every MWh produced not just those MWh produced by wind turbines. And if our electricity markets are functioning that is a saving that could be passed on to consumers.

The electricity grid infrastructure needed to accommodate increasingly large amounts of renewable energy  and create effective competition in a single market in electricity includes a new offshore grid in Europe’s Northern Seas (North Sea, Irish Sea and Baltic Sea), as well as a number of improved interconnections across continental Europe (especially between Spain and France but also between Germany and its neighbours, across the Alps and in eastern and south eastern Europe).

HVDC cables are an attractive new technological option for long-distance electricity superhighways such as the offshore grid that is required in the near future, says the new report.

The report also reveals that flexibility will need to be a key feature of European power systems in the future. This means power generation will have to be more flexible to take into account variable sources of power such as wind and solar. Smart grids will be needed to allow management of demand as well as improved management of supply, and largely national grids will have to be better interconnected. EWEA’s new report shows how Denmark, Germany, Spain, Ireland and the Netherlands have managed their power systems much more flexibly than in the past.

Daniel Dobbeni, President of ENTSO-E, said: “this report is a very welcome publication with a clear view towards 2020, 2030 and 2050. Together with our Ten Year Network Development Plan, it helps building a common understanding on the major issues surrounding the integration of wind energy in the European grids. The report also provides arguments that will certainly be in the centre of policy debate as we can presently observe from the publication of the Commission’s blueprint for an integrated European energy network.”
