Abstract

ABSTRACT To ensure a good return on investment, it is important for power plant operators to set up an asset management program that will ensure reliable operation over the commercial life of the plant. General Electric (GE) has been applying a variety of asset management technologies to improve power plant life and performance for our customers. These methods consider various inputs including equipment design knowledge; asset condition assessed from real-time monitoring and inspection data; and lessons learned from repairing, operating and maintaining thousands of assets globally. In this paper, a subset of that information is applied to develop a methodology to perform risk-based health and life assessments for steam turbines and generators. The method has been used on several steam power plants around the world, to help operators of ageing steam plants make the right decisions related to end-of-life management or life extension.

汽轮机和发电机基于风险的资产寿命管理

为了确保良好的投资回报，发电厂运营商必须建立一个资产管理计划，以确保电厂在商业寿命期间的可靠运行。通用电气(GE)一直在应用各种资产管理技术，为客户改善电厂的寿命和性能。这些方法考虑各种输入，包括设备设计知识;根据实时监测和检查数据评估资产状况;以及从维修、运营和维护全球数千项资产中吸取的经验教训。在本文中，该信息的一个子集应用于开发一种方法，以执行基于风险的健康和寿命评估的蒸汽轮机和发电机。该方法已在世界各地的几个蒸汽电厂中使用，以帮助老化蒸汽电厂的运营商做出与寿命终止管理或寿命延长有关的正确决策。

期刊介绍： Materials at High Temperatures welcomes contributions relating to high temperature applications in the energy generation, aerospace, chemical and process industries. The effects of high temperatures and extreme environments on the corrosion and oxidation, fatigue, creep, strength and wear of metallic alloys, ceramics, intermetallics, and refractory and composite materials relative to these industries are covered. Papers on the modelling of behaviour and life prediction are also welcome, provided these are validated by experimental data and explicitly linked to actual or potential applications. Contributions addressing the needs of designers and engineers (e.g. standards and codes of practice) relative to the areas of interest of this journal also fall within the scope. The term ''high temperatures'' refers to the subsequent temperatures of application and not, for example, to those of processing itself. Materials at High Temperatures publishes regular thematic issues on topics of current interest. Proposals for issues are welcomed; please contact one of the Editors with details.
