摘要
针对热工对象低通滤波特性,以单相受热管过热器为对象,利用泰勒展开式取得其低阶近似公式,根据过热汽温的物理性质和动态特性,对所得公式进一步改进,提出了适用于不同工况的通用传递函数,能满足动态特性分析与实时仿真的需要,具有简单、方便、实用的特点,可用于改善电站汽温的控制.
In view of the properties of a lowpass filter of the thermal objects,the low-order approximate formula for the single-phase heated tubes,called super-heater tubes,is carried out by using the Taylor series.According to the physical properties and dynamic behavior of superheated steam,the improved formula and its application method are proposed,which are suitable for dynamic characteristic analysis and real-time simulation in different conditions.The method has the advantages of simplification,convenience and practicability,so it can be used to improve performance of steam temperature control in power plant.
