Actions Before... and After a Flood

摘要

Flooding can cause Severe Damage to Substation equipment and lead to interruptions in service continuity and widespread outages. This article covers some of these impacts and how to harden substations against them. It also discusses field-proven means of recovering from such events. We include a detailed discussion of a case history: a 1993 flood that resulted in US$10–15 billion in losses. The best practices that emerged from the efforts of the major U.S. utility that dealt with it, Union Electric (UE, now known as AmerenUE), are also described.
