Foreign Electronic And Electrical Engineering

With the growth of the installed capacity and the proportion of REG, mainly including wind power and PV power generation, the stable operation of REG and AC/DC transmission systems has become a technical bottleneck for the sustainable development of REG. Since 2009, broadband oscillation incidents have occurred frequently in REG and AC/DC transmission systems in China and some foreign countries, resulting in severe consequences such as large-scale tripping-off of REG units, damaging equipments, and an increasing curtailment of wind and PV power generation. However, there are great difficulties and challenges for the analysis and mitigation of broadband oscillation.

Zuken has released an update to E³.series 2017, which marks another milestone in the continuous evolution of Zuken’s powerful electrical, wire harness, and fluid engineering design tool.

The History of Mercury Living Presence
The year was 1950. The record industry was recovering from the 'battle of the speeds', which pitted RCA Victor, with its 45-rpm disc, against Columbia Records, inventor of the microgroove long-playing record. (The 78-rpm shellac disc had just suffered a swift demise.) In the aftermath of the protracted struggle, the unexpected happened. Both sides won: the 45-rpm became the preferred speed for popular music at the time and the LP was adopted as the industry standard for classics and other 'long-playing' programs.
