Hitachi Energy to Supply HVDC Converter Stations for UK's Longest HVDC Link

said the award would lead to investments in new production capacity and large-scale recruitment drives."The integration of renewables requires solutions that make the grid resilient, stable, and flexible. Hitachi Energy’s innovation and long development of voltage sourced converter (VSC) power electronics and control and protection (MACH) technologies meet the requirements alongside many other landmark grid integration projects," Hitachi Energy said.Eastern Green Link 2 will consist of two 525-kilovolt (kV) bipole VSC converter stations connected by 440 kilometers of subsea cable and 70

for comparison with recent seismic activity. If validated, a widescale alarm is raised to alert vulnerable communities.Following a 10-year life refurbishment in 2017, the BPRs are now being upgraded to Sonardyne’s 6G hardware and Wideband 2 communications standard. The installation of low power electronics. new lower power consumption pressure sensors and doubled battery capacity of these maxi BPRs will significantly reduce maintenance visits and costs. Additionally, the acoustic telemetry signals used to transmit data to the surface will also now be fully digital, providing greater resilience

difficult to routinely monitor.” The result was the Autosub Long Range (ALR) development in 2010-11. “It was quite different to the existing subs,” says Furlong. “A lot of new developments were required to enable the increased endurance with a lot of focus on very low power electronics. So we moved from Lonworks to a new system running on Windows CE on what was effectively, mobile-phone based processors.” Not everything was new; the pressure spheres for ALR 6000 were repurposed 1970s forgings that had been manufactured for pop up seismometer spheres. Some of the ALR&rsquo

core is a pair of high-dynamic range scientific CMOS (complementary metal–oxide–semiconductor) cameras, each with 2,560 x 2,160 pixel resolution – double that of SeaXerocks. These are mounted in a 4000 m-rated titanium housing, optimized for AUV mounting, that also includes low-power electronics to control the lasers, strobe illumination, communication, data acquisition and processing.Like SeaXerocks, BioCam uses laser lines, but has two lasers, which are pulsed in synchronization with the camera. These were installed on the NOC’s Autosub6000 to provide an ~8 m swath able to

For this project, we’ve also increased the time between battery replacement to in excess of six years, so it’s a long-life, easy to use system to ensure integrity data acquisition.”(Image: Eni
