Abstract
  • The North American interconnected power systems continuously attempt to hold power system time as close to standard time as possible. All inherent problems associated with normal power system operation make this a difficult task. System time is presently allowed to deviate from standard time by up to two seconds before steps are taken to correct the time error. Present correction methods are manual, time consuming and add to existing operating problems which leads us to the conclusion that the advantages of power system interconnection impose more stringent requirements on load and frequency control. Without precise control of generation and frequency, undesired tie-line flows will result. The Tie-Line-Bias mode of control is examined in detail, with emphasis on present means of controlling system time error. A design concept for automatic system time correction is presented which if accepted by the utilities would eliminate manual initiation of frequency offset periods.
