Abstract:
The present invention relates to an advance control method for automatic electricity generating control in an electric power system, which belongs to the technical field of electric power system dispatch automation. The present invention is characterized in that: firstly, set the generating power PG* of an ideal running state of the local control area of the electric power system; PG*=PD-DeltafKL+Ploss+PTS, set PD+Ploss=PG-PT, then PG*-Delta fKL+PT+PTS; set PG'=PG-Delta fKL-PT, then PG*=PG'+PTS; set current time as tn, carry out a prediction to the ideal electricity generating power at the time of tn+1: PG*F(tn+1)=PG'F(tn+1)+PTS(tn+1), an ideal electricity generating power predicted value: PG*; then adjust corresponding automatic power generating control machine set according to the ideal predicted value of the generating power. The innovated method is in consistence with the physical real conditions and present running conditions of the automatic control process of the electric power system, can efficiently improve the frequency of the electric power system and the power quality of the connecting line, enhance the AGC system use efficiency of the prior art, and arrange water, fire and electricity resources reasonably, facilitating convenience for saving energy and reducing drainage.
