本文介绍了八盘峡水电厂瑞典进口机组改造转轮的研制过程,通过转轮优化设计、全模拟模型试验、真机协联试验和流速仪法效率试验,证明了模型和真机试验的真实可信性。八盘峡水电厂~#5机组改造转轮的研制成功,实现了转轮性能的新突破,达到国内领先水平。 This paper introduces the development process of Sweden imported turbine units for the transformation of the runner in the Bamei-xia hydropower plant. Prove the realities of the model and the real machine test through the optimal design of the runner, the full simulation model test, the real machine coupling test and the current meter efficiency test Credibility. The successful development of the # 5 turbine transformation runner in the Bamei Gorge hydropower plant has achieved a new breakthrough in wheel performance and reached the leading level in China.
