Abstract

The paper describes initial research undertaken, exploring the impact of demand and other environmental factors on the power transmission network. How these factors lead to a determined probability of failure is currently determined through a set of complex equations. Demand, or loading, is expected to be the principal factor on the expected life of transmission assets such as transformers. The long-term aim of the research is to understand the likely impact of electrification of vehicles, the associated increased demand on the network, leading to the prospect of a deterioration of the network assets. This initial research suggests that transformer ageing is highly sensitive not only to the average and maximum demand in the network but also to other environment factors. Recommendations from this research will help power transmission companies to more effectively manage their assets through a more robust understanding of the ageing of assets as a consequence of Governmental policy shifts on electric vehicle uptake.

输电资产敏感性分析:变压器老化特例
本文描述了所进行的初步研究,探讨了需求和其他环境因素对输电网的影响。这些因素如何导致一个确定的失效概率,目前是通过一组复杂的方程来确定的。需求或负荷预计将成为影响变压器等输电设备预期寿命的主要因素。该研究的长期目标是了解汽车电气化可能产生的影响,以及相关的对网络的需求增加,导致网络资产恶化的前景。这项初步研究表明,变压器老化不仅对电网的平均和最大需求高度敏感,而且对其他环境因素也非常敏感。这项研究的建议将帮助输电公司更有效地管理他们的资产,通过更深入地了解政府对电动汽车采用的政策转变导致的资产老化。
