The Development of a Control and Monitoring System for a Naval Steam Power Plant

蒸汽动力装置系统复杂 ,设备多 ,需要控制的参数多 ,大部分被控对象的特性无法用简单的数学模型来表示 ,装置运行时参数间相互关联 ,耦合关系复杂 ,许多被控参数用简单的单回路控制无法满足使用要求。而船用蒸汽动力装置负荷变化频繁 ,且变化幅度大 ,其控制系统的技术难度大。本文作者介绍了某船用蒸汽动力装置集中控制监测系统的组成。

Due to its complicated system, the presence of many equipment items and the large quantity of needed control parameters a steam power plant has a majority of its controlled objects not liable to be represented by simple mathematical models. During the operation of the plant many parameters are interrelated and involved in a complicated coupled relationship. Numerous controlled parameters cannot meet usage requirements if a single loop control is employed. Moreover, a naval steam propulsion plant features a high frequency of load changes and a wide range of such changes, resulting in a control system, the implementation of which demands sophisticated technical skills. In light of the above the authors present the composition and functions of a centralized control and monitoring system for a naval steam propulsion plant along with some innovative approaches of that system.
