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.
Abstract:
In view of the properties of a lowpass filter of the thermal objects,the low-order approximate formulafor the single-phase heated tubes, called super-heater tubes, is carried out by using the Taylor series. Accord.ing to the physical properties and dynamic behavior of superheated steam , the improved formula and its appli-.cation method are proposed, which are suitable for dynamic characteristic analysis and real-time simulation indifferent conditions. ’The method has the advantagea of simplification, convenience and practicability, so it canbe used lo improve performance of sleam temperature control in power plant.
