摘要

开发了一种功能强大的机组诊断监测工具，利用在线局部放电(PD)测量的分析结果，对定子绕组绝缘状况进行可靠的评估。介绍了这种永久安装的连续PD监测系统的主要特点和优点，包括实时评估状态趋势和报警启动能力。目的是识别和评估定子绕组绝缘系统的状态变化，从而改进基于状态的预测性维护策略。这有效地降低了设备的整体生命周期成本。给出了基于在线PD测量评估的汽轮发电机组关闭的示例，以避免过早故障并允许执行纠正性维护工作。

Assessed condition trending system (ACTS) a tool for generator on-line diagnostics

A powerful tool for unit diagnostic monitoring has been developed which provides a reliable assessment of stator winding insulation condition by using analysis results from on-line partial discharge (PD) measurements. The main features and advantages of this permanently installed continuous PD monitoring system that includes real time assessed condition trending and alarm initiation capability will be presented. The objective is to identify and evaluate condition changes of the stator winding insulation system and thus to improve condition-based and predictive maintenance strategies. This effectively reduces the overall total lifecycle cost of the unit. Examples are given where based on the assessment of on-line PD measurements on turbogenerators machines were shut down in order to avoid premature failure and to allow for corrective maintenance work to be performed.
