摘　　要：由于水面核电厂长期在倾斜摇摆状态下运行,导致蒸汽发生器水位测量无法直接采用陆上核电厂成熟的差压式液位测量技术。本文结合差压式液位测量原理,在理论计算分析的基础上提出一种适用于水面核电厂的蒸汽发生器水位测量改进方案,并通过倾斜摇摆台架进行了试验验证。验证结果表明,该改进测量方案能够在水面核电厂倾斜摇摆环境下,快速跟踪各种工况下蒸汽发生器水位的变化,测量稳定可靠。The differential level measurement technology used in land nuclear power plants(NPPs)cannot be directly applied in the measurement of steam generator(SG)water level of floating NPPs because of the long-term inclination and swing condition.In this paper,combined with the principle of liquid level measurement by differential pressure,SG water level measurement improvement scheme for floating NPPs is proposed based on theoretical calculation and analysis.This improvement scheme was tested and verified by inclination and swing test bench.The related experimentation verifies that this improvement scheme can track the water level under various working conditions and get the accurate water level under inclination and swing condition.
