Improvement in Power System Frequency Control by Automatic Follow-up Regulator of Thermal Power Plant |
| Abstract |
An improved control method in turbine control system is proposed. By automatic follow-up design, power system frequency may be maintained within prespecified range. Base or half load control is possible by distributing power plant load allotment. Otherwise, diminutive frequency-load control is dine by governor-free operation in power plant. This paper proposes governor-free operation which is automatically followed by load-limitter setter. The condition which limits governor action may be somewhat improved within boiler condition by this idea. This design has been implemented at Samchunpo thermal power plant. The improved practical results are shown. |
