A Balancing Authority notices that Operating Reserve has steadily declined throughout the hour. What is the most likely cause? a) Loss of a large generator in the area b) An inaccurate load forecast c) Loss of a major transmission line d) A malfunction of EMS - b) An inaccurate load forecas...

What percentage of load gives a 1 Hz change in an island condition? - 6-10% (Think 6-10 day island vacation) If ACE is Zero but system Hz is off, what should a system operator do? - Nothing! ACE bias and interchange schedule will improve frequency If ACE is Zero, why not adjust generatio...

A misoperation occurred when an overhead ground wire on a 230KV transmission line between two substations broke and fell across A phase of the line. One of the line circuit breakers failed to open causing the breaker failure relay to pick up and as a result tripped the entire substation bus off line...
