Analysis and improvement of primary frequency adjustment system in power plant

Abstract

Abstract: Abstract:Under the background that Henan provincial electric power scheduling center carries on examinations of primary frequency adjustment of unified scheduling generators, given the current low quality primary frequency adjustment rate for Huadian Luohe Power Company′s firststage 2×330MW generator, we conduct a indepth analysis of frequency adjustment system, and improve it from the aspects of hardware, software, control logics. Finally, we achieved a substantial increase in quality rate.

Key words: Keywords:thermal power plant, primary frequency adjustment, quality rate
