摘要/Abstract

摘要： 设计了一套基于模糊数风险分析法的智能汽轮机控制系统：通过对汽轮机的运行特点进行研究，将汽轮机的启动过程划分为若干个步序依次执行；采用模糊数相似度风险分析法，对汽轮机启动过程中的风险进行预估和管控，并结合运行人员经验，以确定是否执行下一步序，据此规划适宜的启动路径。该技术实现了采用非热应力模型的汽轮机自启动控制，对国产汽轮机自启动技术的研究与应用具有一定的参考价值。

Abstract: An intelligent control system for steam turbines is designed based on the risk analysis of fuzzy numbers. Through studying the operational characteristics of steam turbines, the startup process is divided into several sequential steps. By using the risk analysis method based on the similarity of fuzzy numbers, the risk in the startup process of steam turbines is forecasted and controlled. The execution of the next step is then determined by combining the experience of operators, and the appropriate startup path could be planned accordingly. For the first time, this technology realized the self-startup control using a non-thermal stress model of steam turbines, and it provides significant insight on the study and applications of the self-startup technology of domestically produced turbines.

Key words: coal-fired power plant, fuzzy numbers, risk analysis, self-startup technology, execution steps
