In 1999, China's Lijiaxia Power Station successfully put into commercial operation a 400MW hydro-generator equipped with evaporative cooling technology that was entirely developed and owned by Chinese engineers. This marked a major breakthrough in the country’s power generation industry. The generator demonstrated excellent performance, with a low temperature rise, uniform temperature distribution, and minimal vibration, operating at its optimal condition.
The successful implementation of this technology significantly advanced the development, design, and manufacturing of high-performance hydro-generators in China. It enhanced the economic efficiency and safety of large-scale motor operations, while also raising the overall operational standards of the power industry. The project received widespread recognition from both industrial experts and professionals in the power and motor manufacturing sectors, highlighting its importance for China's technological progress.
Research into the electrical insulation properties, heat and mass transfer characteristics of the new non-polluting cooling medium, as well as the cooling mechanisms of motor components under rotating conditions, led to significant advancements in engineering structures. These theoretical and practical studies placed China at the forefront of international research in this field. The innovation not only improved the reliability of hydro-generators but also set a new benchmark for sustainable and efficient power generation technologies globally.
