1800V officially launches large-scale application
Recently, the first batch of Sunshine 1800V wind power converters have been successfully installed and shipped. These models with a single capacity of 10MW adopt an insulation design framework that complies with IEC safety standards, providing high-performance and highly reliable technical support for onshore large megawatt wind turbines. This marks the official entry of wind power technology into a new era of higher voltage levels and higher power density. Sunshine Wind Energy, driven by innovation, injects surging power into the upgrading of large megawatt wind power technology.
In response to the demand for ultra high power units, the Sunshine 1800V wind power converter reduces the current of the electrical transmission system by increasing the voltage level and power density. With the goal of reducing cable costs and losses, improve the operating conditions of rotor slip rings. Sunshine collaborates with supply chain innovation breakthroughs, breaking through technical barriers from IGBT to low-voltage electrical appliances, promoting the construction of domestic solutions for the entire chain, and ensuring the implementation of technology. Based on the performance advantages of three-level topology, the 1800V product is prospectively adapted to the application scenarios of onshore 10-15MW and offshore 15MW and above units, providing a more efficient and economical energy conversion technology template for wind turbine electrification.
Compared to traditional 1140V systems, 1800V wind power converters have higher power conversion efficiency, reducing grid side current by 37% at the same power level, providing strong support for large megawatt units. Sunshine Wind Energy strictly follows the high voltage safety design standards and adopts the new generation of 2300V IGBT devices. Through XHP packaging technology, it reduces the number of modules in parallel, improves reliability, reduces operation and maintenance difficulties, and comprehensively guarantees the safe and stable operation of large megawatt units.
