摘要
传统汽轮机模型将锅炉看作一无限大蓄热环节,并未考虑主蒸汽压力的变化,这使得主蒸汽流量仅为阀门开度的函数。然而,实际过程中主蒸汽压力会因锅炉蓄热状态以及汽轮机阀门开度变化会产生波动,并非处于恒定状态。因此若忽略主汽压影响,所建模型仿真精度将严重受限,本文在传统汽轮机模型基础上考虑主蒸汽压力变化因素,建立了更为精细的汽轮机模型,并通过仿真研究了主蒸汽压力对汽轮机动态响应的影响。
The traditional steam turbine model considers the boiler as an infinite heat storage unit without considering the changes in main steam pressure,resulting in the main steam flow rate being only a function of valve opening.However,in the actual process,the main steam pressure will fluctuate due to changes in boiler thermal storage status and turbine valve opening,and is not in a constant state.Therefore,if the influence of main steam pressure is ignored,the simulation accuracy of the built model will be severely limited.This article considers the factors of main steam pressure changes on the basis of traditional steam turbine models,establishes a more refined steam turbine model,and studies the impact of main steam pressure on the dynamic response of the steam turbine through simulation.
