随着水力发电技术的不断发展,低水头泵站的能源利用效率逐渐成为研究的重点,针对低水头泵站反向发电中存在的效率有待提高、振动噪声大及谐波干扰等技术难题,提出基于四象限变频器优化方案。通过淮阴二站工程验证,结合移相变压器多单元级联拓扑与无速度传感器矢量控制技术,实现低水头(1.8~3.3 m)条件下机组高效稳定运行。详细分析不同叶片角度下的水泵发电性能,比较同转速发电与变频发电模式下的运行效率、振动性能和经济效益,相关研究可为低水头泵站的反向发电提供技术支持。

With the continuous development of hydropower technology, the energy utilization efficiency of low head pumping stations has gradually become a research focus. In response to the technical problems of low efficiency, high vibration noise, and harmonic interference in reverse power generation of low head pumping stations, an optimization scheme based on four-quadrant frequency converters is proposed. Through the verification of the Huaiyin Second Station project and the combination of phase-shifting transformer multi unit cascade topology and sensorless vector control technology, efficient and stable operation of the unit under low head (1.8-3.3 m) conditions has been achieved. Detailed analysis of the power generation performance of water pumps under different blade angles, comparison of operating efficiency, vibration performance, and economic benefits between the same speed power generation and variable frequency power generation modes. Relevant research can provide technical support for reverse power generation in low head pumping stations.
