摘要: 在汽轮机热力循环中,测量系统具有冗余测点。现场一般采用主给水流量、主凝结水流量和给水泵进口流量作为性能计算中的主流量。采用数据校正方法,利用冗余的流量测点信息,对某一实际电厂的性能数据进行数据校正计算,并分析了性能计算结果不确定度的变化。结果表明,数据校正可以有效减小计算结果的不确定度。

Abstract: In the steam turbine thermodynamic cycle, the measuring system has provided redundant measuring points. Generally, the main water flow, the main condensate flow and the feed water pump inlet flow are chosen as the mainstream in the on-site performance calculation. In this paper, by using the data reconciliation method, the redundant flow measurement point information is taken to perform data reconciliation calculation regarding the performance data of a real power plant. Then the uncertainty changes of the calculation result are analyzed. The result shows that the data reconciliation can effectively reduce the uncertainty of the calculation result.

Key words: steam turbine, thermodynamic performance, data reconciliation, uncertainty, redundancy, heat rate
