According to finance.sina.com.cn, the 23MW offshore semi-direct drive permanent magnet wind generator, jointly developed by Shanghai Electric and Shanghai Electric Wind Power, has recently completed all its tests.

The test results show that all indicators, including electrical performance, temperature rise, vibration, and noise, meet the design requirements. The generator demonstrates excellent comprehensive performance and possesses the capability to operate at a super-rated power of up to 25MW. This represents another significant breakthrough for Shanghai Electric in the large-megawatt wind generator field, following the 16MW semi-direct drive wind generator, providing core technical support for Shanghai Electric to expand in the high-power wind power equipment market.

The successfully developed 23MW semi-direct drive permanent magnet wind generator benchmarks against international cutting-edge design concepts and integrates multiple core key technologies to create advantages in efficient, stable, and reliable operation. Relying on high-precision electromagnetic design and simulation analysis technology, the product forms a triple performance advantage of high efficiency, high anti-demagnetization capability, and high power density. It adopts multi-physics field coupling simulation analysis technology to carry out in-depth collaborative design combined with the operating conditions of the whole machine's electrical system and transmission chain. At the same time, the product is equipped with high-efficiency cooling technology, precise shaft current suppression technology, and high-reliability insulation technology, comprehensively ensuring that all performance parameters fully meet the standards. Multiple technical indicators are superior to the established industry standards, significantly improving the unit's environmental adaptability and operational stability under complex offshore conditions.

Since deeply cultivating the wind power equipment field, Shanghai Electric has continuously promoted the core technology research of large-megawatt wind generators and continuously improved the wind power product portfolio. In recent years, combined with the development needs of the wind power motor industry, Shanghai Electric has successfully developed 6MW-class onshore semi-direct drive permanent magnet wind generators and achieved mass production. At the same time, focusing on the offshore wind power market, it has successively launched 13.XMW, 14.XMW, 16.XMW and other series of offshore semi-direct drive permanent magnet wind generators, realizing full coverage of wind power products from onshore to offshore and from small and medium megawatts to large megawatts.
