The world's first flexible DC power grid is coming soon
At 17:00 on the 10th, the national grid ±500 kV Zhangbei flexible DC power grid project line successfully withstood the impact of instantaneous short-circuit current, and completed the last "big test" before the commissioning-artificial ground short-circuit test. At this point, the world's first flexible DC power grid is officially equipped with power transmission conditions.
State Grid Jibei Power stated that flexible direct current (flexible) is a new generation of direct current transmission technology with a voltage source converter as the core that emerged in the 1990s. As we all know, conventional direct current can only be located in point-to-point transmission instead of networking due to unidirectional current flow; flexible direct current uses the most advanced voltage source converter (VSC) and full control device (IGBT), which is quite In a fully controllable water pump, the direction, speed and flow of water flow become precise and controllable. This "flexible" and flexible feature allows it to play a major role in the large-scale grid connection to intermittent and fluctuating renewable energy.
The total investment of the Zhangbei flexible DC power grid test demonstration project is 12.478 billion yuan. New 4-terminal converter stations and 666 kilometers of lines in Zhangbei, Kangbao, Fengning and Beijing will be built, with a total converter capacity of 9 million kilowatts. It is expected to be put into operation before the end of June. (Reporter Qu Jian)
Matting Agent For Plastic Coatings
Description
1, Matting Agent popular used for the matte plastic coatings. It is synthetic amorphous micronized precipitated silica appearing as white powder and for both solvent-based and water-based system. Advanced matting efficiency is achieved by using silica with high pore volume and by fine control of the particle size and particle size distribution. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant ï¬lms of high surface quality. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.
2, Silica Matting Agent suitable used for plastic coatings. It provided high matting efficiency, excellent coating appearance and better transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity.
