September 3, 2010 - Thank you for visiting STRI at CIGRE

STRI participated in CIGRE 2010 in Paris both with several technical papers and contributions for the questions of special reporters and a small exhibition including the STRI IEC61850 interoperability test equipment. Around 150 CIGRE delegates visited STRI exhibition stand to discuss issues on insulation, line design, HVDC, cable testing, EMF, AC/DC conversion, merging units for optical measurement etc. But a very small & smart device created the highest interest among many of our visitors – The Smart Temperature Sensor.

June 17, 2010 - STRI - The Ultra HVDC Specialist

Ultra High Voltage Direct Current (UHVDC) with 800 kV is now being implemented in China and India to efficiently transmit large amounts of energy over long distances from remote hydro power plants. STRI has been involved in the testing of this new technology during the past couple of years both for China and India. This includes testing of basically all components such as bushings and converters as well as a long term test of a complete system during different seasons energized at 850 kV for ABB. Now a number of tests have been performed for the transmission line isolation for the first 800kV UHVDC line in India. Read more...

May 24, 2010 - How does the vulcano ashes affect the power grid?

On Thursday, the 15th of April STRI has been approached by Vattenfall and Svenska Kraftnät for fast investigation on possible influence of eruption of Eyjafjallajökull volcano on outdoor insulation in Sweden (see example of eruption and ashes on the road nearby the volcano taken on the 16th of April). In the worst case one should be prepared for washing of some overhead lines and substations. During the same day STRI organized a number of telephone meetings with experts from: CRIEPI (Japan), Landsnet (Iceland), NIIPT (Russia) and meteorological consultants from Norway. An intensive literature search revealed practical experience from BPA and Portland General Electric Company from USA. Read more...

March 31, 2010 - STRI hosts the first interoperability test for wind energy communication

IEC 61400-25 is the first international communications standard designed especially for wind power applications. IEC 61400-25 is based on IEC 61850, which over the last five years has revolutionized substations automation. The new standard for wind power applications includes both standardized names and models of wind plants components such as turbines and rotors, as well as maps of this data to several different protocols. Between March 23rd and 25th a workshop was held at STRI in Ludvika with 20 participants from 5 manufacturers of PLC (Programmable Logic Controllers), 4 manufacturers of SCADA and test clients as well as some observers from interested power companies like Vattenfall and Statkraft.
