【 摘 要 】

As an important equipment in thermal production process of thermal power unit, auxiliary equipment of steam turbine, such as feed-water pump, whether it can operate safely and economically is very important for normal operation of thermal power plant. Considering that the auxiliary machine on the side of the steam turbine of a power plant has the characteristics of high failure rate, a state monitoring and evaluation method based on the matter-element theory is proposed. Based on the establishment of the monitoring index and evaluation model of the auxiliary engine on the side of the steam turbine, the correlation degree between the main operating parameters of the auxiliary engine and the monitoring model is determined. According to the value of correlation degree, the operating condition of auxiliary machine is judged to be excellent, good, qualified or malfunction. Finally, a 300MW steam feed pump is taken as an example to prove that this method has certain engineering application value.
