Real Time Condition Monitoring for Samsung Mobile Display’s New Production Line

Samsung Mobile Display Co., a venture between Samsung Electronics Co. and its sister unit Samsung SDI Co., are building a new plant that produces displays used in phone handsets and small televisions.
The plant in Asan city, 42 kilometres southwest of Seoul, South Korea, will be completed by July next year. Samsung Mobile Display plans to spend 2.5 trillion won (US$2.11 billion) on the plant.
The joint venture will produce active-matrix organic light-emitting diode (AM OLED) displays, which are used in portable devices such as mobile phones and small TVs.
LIOS Technology recently completed the installation of its real time condition monitoring system supervising three 154kV high voltage cable systems on site. Condition monitoring is based on LIOS’  Distributed Temperature Sensing (DTS) System OTS20P with a 16 channel fibre switch.
The distributed temperature profiles of the energy transmission systems made by Prysmian Cables & Systems are measured in real time by embedded fibre optics using  FIMT . The DTS readings are visualised at the central control and dispatch centre ensuring save operation and allowing exploitation of the high voltage cable routes at full capacity potential.

Powering Europe – new report sets out vision for the future European grid and markets – EWEA

A new report by the European Wind Energy Association – Powering Europe – which sets out its vision for the European grid of the future has been launched today at the Grids 2010 conference in Berlin.

‘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.”

10 Tips for Electric Utilities to Implement Condition Monitoring Successfully

Real time condition monitoring has become a well accepted tool for thermal assessment and accurate rating of transmission and distribution assets. However, the use of fibre optics as sensors for distributed temperature sensing (DTS) is a rather complex technology with many parameters to consider.

1. Selecting the Right Fibre
   For measurement ranges of up to some 18 km the GI 50/125 multimode fibre typically provides the best distributed temperature measurement performance and allows deployments of less expensive multimode DTS systems. For longer ranges of more than 20 km singlemode fibres compliant to ITU-T G.652.C or D enable distributed temperature sensing even for applications like subsea cables.
2. Long Term Performing Fibre
   Especially multimode fibres are available in different qualities. Besides attenuation limits the bandwidth has to be specified to > 500 or even >1000 MHz*km @ 1300 nm as it is important to achieve measurements with good spatial resolution also from remote distances. In order to ensure long term service life of the fibre it is recommended to select phosphorous free qualities only. A securely embedded fibre within the high voltage power cable in form a FIMT – fibre in metal tube – prevents damages in course of cable laying and delivers superior temperature information due to its proximity to the conductor.
3. Spatial Resolution at Most Remote Distances
   The spatial resolution along the entire fibre length shall be 1.5 m or better. As the spatial resolution degrades with a function of distance with some DTS technologies the actual spatial resolution at the most remote distance shall be indicated.
4. 24/7 Operation
   DTS equipment shall be powered directly by secure substation DC supply, so even critical moments during mains outages are covered by condition monitoring. The DTS system shall operate independently from any kind of PC based system; Windows operating systems shall be solely used for data visualisation purposes. Equipment based on Windows operating systems drop statistically to MTBF ratings below 12 months.
5. Direct Link to SCADA
   Condition monitoring data shall be available at real time, so the DTS shall be capable to send its measurements and derived events directly to the operator’s SCADA or overall management system using protocols meeting substation standards based on IEC or DNP.
6. Reliable DTS Equipment with Proven Track Record
   Reliability and long lifetime are essential for investment goods like condition monitoring systems. The DTS laser diode and other key components shall be tested according to the Telecordia standard GR-468 or similar with medium lifetimes >25 years. The mean-time-between-failures (MTBF) rating of the DTS shall be higher than 25 years and based on a proven track record. Manufactures with ISO 9001 and ISO 14001 certification are recommended.
7. Preference for Single End
   Known from the early days of DTS systems the double ended or loop fibre set up is still sometimes requested today. However, latest DTS systems achieve measurements with sufficient temperature and spatial resolution at fast cycle times even at single ended fibres. The single ended measurement makes a more economic use of the DTS (longer range coverage, less channels occupied) and is the recommended operation mode for typical power cable monitoring installations.
8. Ampacity Predictions by RTTR
   Real Time Thermal Rating (RTTR) removes all uncertainty left by the DTS measurement. The power cable’s sheath temperature measured by the DTS gives a good idea of the temperature of conductor, but unless an accurate model for the conductor is provided there will be some uncertainty left. Sophisticated RTTR systems cover apart from steady state also the more critical transient operations based on IEC 60853 for this calculation and provide trustable ampacity predictions.
9. The Software Speaks Your Mother Tongue
   The DTS operation software shall be user friendly and available in the native language of the operator. This helps to prevent misunderstandings and encourages staff to use the system with pleasure.
10. More than Temperature
    Real time thermal assessment of the T & D grid is a powerful tool that allows accurate rating and ensures save and stable grid operation. By adding other real time diagnostics (i.e. partial discharge), failure uncertainty is reduced and maintenance procedures can be optimized. Aim for an integrated Global Condition Monitoring solution.

Congratulation to LIOS Technology GmbH for 10 successful years!

The team of LIOS Technology, Cologne

This year LIOS Technology can celebrate its 10 years anniversary. But the activity which formed the basis of today’s LIOS Technology already took its start in 1995. An innovative group within the German cable company, Felten&Guilleaume (F&G) saw an opportunity for developing a distributed temperature sensing system technique for condition monitoring of power cables, and hence making it possible to exploit the full capacity potential of installed high voltage cable routes.

Containment Integrity Monitoring Solutions for LNG Carriers – Cryogenic tests for the validation of a cargo containment system for LNG ships

INTRODUCTION
This report shows the results of cryogenic test for confirming the KC-1 cargo containment system which will be applied to LNG ship. Open mock-up tank has already been built to prove the fabrication, assemble and construction procedures of KC-1 membrane system for ship application. A LNG carrier closed type mock-up tank as recently built, hereafter CMT, of the KC-1 type membrane system.

Experimental stress analysis systems equipped with strain gages and fibre optical sensors have been reflected in the design to perform a cryogenic test. CMT cryogenic tests were conducted by filling and discharging LNG 5 times and all the tests have been successfully completed in October 2009.

The purpose of construction and cryogenic tests of CMT are as follows

(1) Confirming the stability of KC-1 membrane system during cryogenic test

(2) Improving the quality control system of membrane and insulation system of LNG tank which assures the reliability of LNG carrier

(3) Evaluating the applicability of automatic welding machine on KC-1 membrane system

(4) Intensifying the techniques of design, material, fabrication and inspection required for the design of LNG carriers

SPECIFICATION OF CMT
This size of the tank is 12m long, 14 m wide, 7m high and inner volume of 250m3. Its construction was commenced in September 2008 and brought to completion in April 2009.

CMT is connected to DCS (Distributed Control System) of Pilot LNG Plant and operations are controlled at remote control room. CMT’s cryogenic tests were performed by repeated charging and discharging LNG for 5 times. Before operation, pre-cooldown test were also performed to lower the temperature of primary membrane to LNG temperature by spraying liquid nitrogen. Construction and cryogenic tests of CMT adopted in KC-1 membrane system were made with the purpose of consolidating the design/fabrication technology, establishing the building system for LNG carriers, establishing the quality control for construction procedure and proving the KC-1 membrane system experimentally.

CMT OPERATIONS
The following figure shows the variation of liquid level and primary membrane’s temperature during operation. IB and IBS spaces filled with nitrogen were sampled regular intervals to check the leakage of LNG during operation. After the operation of 1st and 5th pre cool down, CMT was opened and primary membrane system was checked through visual inspection.

TEMPERATURE MEASUREMENT SYSTEM
Liquefied natural gas (LNG) normally has a temperature of -162°C, so all the storage facilities such as insulation and hull systems are subject to temperature decrease caused by long-term storage. RTD sensors were installed at several points of CMT for the purpose of monitoring CMT only for the period of operation. The LIOS fibre optic temperature measurement for CMT structure has been developed to investigate the temperature distribution of KC-1 membrane system.

In case of KC-1 type cargo containment system, cone type membrane anchor structures are fixed in hull and support the reaction force of membrane during operation. Since the fibre optic sensor cable is coiled around cone anchor and measures the temperature every 50cm interval, it is possible to investigate the temperature distribution of CMT.

Two fibre optic cables were installed in the insulation and a third one was included on the cone anchor to investigate the distribution of temperature during operation. The following figure shows the whole temperature distribution of CMT during operation. All the measured data were plotted at the maximum LNG level.

The LIOS DTS system as well as the design of the applied fibre optic sensor cable could be successfully approved as an effective and reliable integrity monitoring system for the KC-1 cargo containment system. The cryogenic temperature measurements are precise and stable in course of the entire test period.
