Electric System Disturbance on the Consolidated Edison Company of New York, Inc., System. Staff Report on July 13--14, 1977

摘要

The President ordered a prompt and thorough investigation of the blackout which occurred on the evening of July 13, 1977, at about 8:35 p.m., when the electric system of Consolidated Edison Co. of New York (ConEd) was hit by lightning. The lightning caused one 345-kV line from Ladentown to Buchanan to go out of service and at the same time Indian Point No. 3 generator was disconnected from service. In a spreading series of events, another 345-kV line went out of service. Other events followed necessitating severing of all ConEd's connections with other utilities to the North and East and within an hour all ConEd's connections with all other utilities had been severed. Immediately thereafter, the Federal Power Commission staff undertook preliminary investigation and analysis pursuant to Section 2.11 of the Commission's Regulations under the Federal Power Act. This report contains the preliminary conclusions and recommendations based on the first phase of the investigation. (ERA citation 03:024312)
