【摘要】 在热力系统优化调度计算中,采用常规方法所建立的热电联供汽轮机模型通常精度较差。本文提出了依据实时运行数据采用线性规划的汽轮机特性建模方法,在建模允许的误差范围内它反映了大多数正常运行数据所表达的共同变化规律,同时对异常数据进行剔除。采用该方法的建模结果表明该方法可以获得热电联供汽轮机准确的特性方程。更多还原

【Abstract】 In the calculation of optimal dispatch for a thermal system, the model built by the conventional method for power-heat cogeneration steam turbines is of poor accuracy. In this paper, a linear-programming modeling method is adopted based on the field operation data, which reflects the common regulation of variation expressed by the normal data in the majority within the allowed modeling error and discards the abnormal data at the same time. The modeling result based on the field operation data shows that an accurate equation of performance for a power-heat cogeneration steam turbine can be achieved.更多还原
