From October 18 to 20, CWP 2021 was grandly held in Beijing New International Exhibition.
As one of the largest annual events in the global wind power industry, CWP 2021 has an exhibition area of 60000 square meters and more than 600 exhibitors. More than 100 speakers and thousands of delegates at home and abroad were invited to focus on the future of China's energy revolution and share the new development concepts of innovation, coordination, green, openness and sharing.
In this wind energy exhibition, Times Electric carrying semiconductor components and modules, wind power converters and marine equipment made an amazing appearance.
l l power semiconductor components and modules
The chip adopts the fifth generation TMOS technology and has the characteristics of low conduction voltage drop, low switching loss and high reliability. It has been widely used in medium and low voltage module products, covering the current range of 300a-3600a, and the chip platform covers the voltage range of 1200v-1700v. The module products have been widely used in new energy wind power, photovoltaic, frequency converter, SVG, medium frequency induction heating and other fields.
l l 5. Xmw three-level doubly fed wind power converter
The product provides the integrated design of converter, main control and auxiliary transformer, which makes the whole cabinet lighter, operation and maintenance more convenient and cost-effective. The three-level design and excellent modulation technology ensure the overall efficiency of 98.5% and the lowest harmonic is only 0.7%. Stronger fault traversing capacity and overspeed carrying capacity of weak current network, combined with the digital operation and maintenance platform, can realize independent networking, remote software update and intelligent fault diagnosis, and create more value for the host plant and the owner.
l l "water dragon" shallow water trencher
The equipment is mainly used for cable laying of offshore wind farms. It has intelligent technologies such as intelligent walking, active steering, accurate navigation and positioning, cable detection and cable tracking. The seabed operation depth can reach 200m, the trench excavation depth can reach 3M, and the cable laying speed can be increased to 0.75km/h, which solves the problem that it is difficult for traditional equipment to dock due to the ship's water depth Low operation efficiency. Its unique "laying before burying" technology has greatly improved its work efficiency compared with the traditional "laying while burying", which can be close to the wind power pile foundation to the greatest extent, make the pile foundation cable fully buried and protected, and reduce the later operation and maintenance risk. It is a low-cost cable laying tool for offshore wind energy resources.
