Abstract

The article presents the results of analyzing the failure statistics of the main components of steam turbines of thermal power plants. Based on the results of the analysis established that the complexity of technological processes, taking into account turnaround time, failure rate, the production cycle of the equipment residual life allows to develop approaches to assessing the health of each element with the aim of obtaining reliable and representative sample of failure statistics to reliability assessment of steam turbine plants. It is shown that the statistics of finding equipment in a state of partial failure is an important factor for improving the overall reliability of equipment. The results obtained can be used to create predictive models that provide approaches to prolonging the operational state of elements of steam turbine installations, as well as for implementing projects of digital energy systems that include subsystems for monitoring and diagnostics of power equipment of thermal power plants.

基于可靠性指标的汽轮机实际技术状态评估方法的发展

本文介绍了火电厂汽轮机主要部件失效统计分析的结果。根据分析结果确定，考虑到工艺过程的复杂性，考虑到设备的周转时间、故障率、生产周期和剩余寿命，可以制定评估每个元件健康状况的方法，目的是获得可靠的、有代表性的故障统计样本，以进行汽轮机厂的可靠性评估。研究表明，发现设备局部失效状态的统计是提高设备整体可靠性的重要因素。所获得的结果可用于创建预测模型，为延长汽轮机装置元件的运行状态提供方法，也可用于实施数字能源系统项目，其中包括用于监测和诊断火电厂动力设备的子系统。
