摘要 可靠的在线监测系统对保障核电站性能监控与优化运行具有重要意义,而监测系统的可靠性与传感器的布置、精度以及冗余性等密切相关。以某核电站的低加系统为研究对象,分析了线性化方法及两步法两种双线性的数据校正问题的求解过程。最后通过案例数据,分析了两种方法在校正结果、计算时间、故障引入的表现,分析结果可有效指导实际电厂低加系统实施数据校正过程。 A reliable online monitoring system is of great significance to ensure the performance monitoring and optimal operation of nuclear power plants, and the reliability of the monitoring system is closely related to the arrangement, accuracy and redundancy of sensors. This paper takes the low pressure feed water heater system of a nuclear power plant as the research object, and analyzes the solution process of the linearization method and the two-step method for bilinear data correction problems. Finally, through the case data, the performance of the two methods in the correction results, calculation time, and fault introduction is analyzed. The analysis results can effectively guide the data correction process of the actual power plant low pressure feed water heater system.
