Aiming at the problems of excessive vibration, high noise and low efficiency existing in the same-speed reverse power generation of Huaiyin No.2 Pumping Station, a scheme including a four-quadrant frequency converter, a bypass system and protection setting is proposed, and its mechanism of action in the reverse power generation process is analyzed. The three-stage architecture of the four-quadrant frequency conversion system provides a topological basis for bidirectional energy flow. The interlocking mechanism of the bypass system solves the safety problem of multi-condition switching. The hierarchical protection system realizes the risk control of the whole life cycle of equipment. The vibration online monitoring system and energy efficiency curve comparison are used to verify the effect. The results show that under the four-quadrant frequency conversion speed reduction power generation mode, the vibration amplitude of the impeller chamber is reduced by 78.11%, the power generation efficiency is increased by 45.05%, and the noise is reduced by 10 dB. Various performances are significantly improved, which provides theoretical support for the standardization of reverse power generation technology in low-lift pumping stations.

针对淮阴二站同转速反向发电存在的振动超标、噪音过高及效率低下等问题，提出了四象限变频器、旁路系统及保护整定的方案，分析其对反向发电过程的作用机制，四象限变频系统的三级式架构为能量双向流动提供拓扑基础，旁路系统的互锁机制解决多工况切换的安全难题，分层保护体系实现设备全生命周期的风险管控，并利用振动在线监测系统与能效曲线对比验证效果。结果表明，四象限变频降速发电模式下叶轮室振动幅值降幅78.11%，发电效率增幅45.05%，噪音降低10 dB，各项性能提升明显，为低水头泵站反向发电技术的标准化提供理论支撑。
