Backup Power Sources:
Blackouts and Brownouts
Michael F. Hordeski
Restoring power to a massive area requires utilities to balance electricity coming from the restarted plants with load demands. An imbalance can trigger more blackouts. Supplementary power sources called black starters are used to re-engage the generators and get auxiliary systems on-line. Once the generators are up, they could flood the grid with too much power and shut it down again if there are not enough substations on-line to draw power.
At the substations, operators must control the power distribution and gradually send more power to areas that need it. As new power plants are connected to the grid, those that are already up and running must drop back their output to stabilize the system.
Essential facilities and services are the first to get their power back.
These include hospitals, police and fire departments, water and sewage- treatment plants. As areas are brought up, they are connected with other nearby regions. This merging can cause destabilizing fluctuations for a while.
By 10 p.m. on the day of the blackout, 50% of affected areas in New
England had their power restored. By 5 a.m. the next day, 50% of Canadian areas were back online. New York was fully restored by 10:30 p.m.
