Development of Mutual Watching System of Control Residue of Each Block in Load Frequency Control System

摘要

A major problem in the current LFC system lies in that its effectiveness cannot be checked. This is because it is very difficult to grasp the amount of the control residue of each area. For each area, the sum of the control residue, self regulation and the net power fluctuations through its tie-lines must be zero. Since fluctuations through the tie-lines are measurable, control residue or self regulation complement to each other. That is, the knowledge of either one makes the other known.
