摘要
机组的能耗特性由热力系统的拓扑结构、运行条件以及运行方式决定,当上述条件给定,则热力系统各部位的状态参数,乃至机组的能耗特性必然确定。本文基于状态空间的理论采用机理分析与统计辨识相结合的混合模型方法,建立了凝汽器变工况模型,并结合实例进行了实践验证。
The energy consumption characteristic of the unit was decided by the operation conditions and the topological structure and the operation mode of the thermal system. If this condition was given, then the each place state parameters and the energy consumption characteristics of the thermal system of the units will be determined. The con- denser variable condition model has been established in this paper, based on state space theory and the mixture model method combined with the mechanism analysis and statistics identification, and it was verified in the example practice.
