摘要/Abstract

摘要：

基于化工企业全厂蒸汽管网配置，针对蒸汽管网波动工况，提出程序化控制应对策略，用程序化控制替代人工决策，避免决策不及时或人员应急处置能力不足而导致的次生事故，减少经济损失，确保装置安全。并在大型机组蒸汽透平跳车工况时，为避免蒸汽管网波动，根据减温减压器调节阀特性参数，提出程序化控制方案，及时稳定蒸汽管网压力，减少因工艺波动造成的经济损失。

Abstract:

Based on the configuration of plant-wide steam network of chemical enterprises, a program control response strategy is proposed for the fluctuation of steam network. Program control is used to replace human decision-making to avoid the secondary accident caused by untimely decision-making or insufficient emergency response capacity of personnel, reduce economic loss and ensure the safety of the plant. When the steam turbine of large compressor unit trips, in order to avoid the fluctuation of steam network, a program control scheme is proposed according to the characteristic parameters of the control valve of temperature and pressure reducer to stabilize the pressure of steam network in time and reduce the economic loss caused by process fluctuations.

Key words: steam network, fluctuation, program control
