摘要

针对适用于燃煤发电机组的熔盐储能系统

建立了蒸汽发生系统的非线性动态数学模型

探究多种扰动作用下系统的动态特性

并验证了模型的准确性。结果表明:静态实验中

在额定工况下蒸汽发生系统中的3个换热器模型仿真结果与设计值的最大误差仅为1.03 K;在不同热负荷下蒸汽发生系统的静态性能也被验证

最大和最小绝对误差分别为0.85 K和0.01 MPa;在动态实验中

熔盐的入口温度变化对蒸汽发生系统出口处蒸汽质量流量的影响最大

其次是熔盐质量流量的变化。

Abstract

A nonlinear dynamic mathematical model of the steam generation system was established for the molten salt energy storage system applicable to coal-fired power plants. The dynamic characteristics of the system under various disturbances were explored

and the accuracy of the model was verified. Results show that in the static experiment

the maximum error between the simulation results and the design values of the three heat exchanger models in the steam generation system was only 1.03 under rated conditions. The static performance of the steam generation system under different heat loads has also been verified

with maximum and minimum absolute error of 0.85 and 0.01

respectively. In dynamic experiments

the change in inlet temperature of molten salt has the greatest impact on the steam mass flow rate at the outlet of the steam generation system

followed by the change in molten salt mass flow rate.
