Abstract

Abstract: An evaluation method of primary frequency regulation (PFR) performance after ultra-high voltage (UHV) transmission line tripping is proposed in order to avoid accuracy problem with current evaluation method. Based on statistical results of normal PFR process, characteristics of PFR process after UHV transmission line tripping are obtained. A new PFT performance index system is established according to described characteristics to complement the problems with existing method. The proposed method can describe PFR process from different units after UHV transmission line tripping clearly and accurately. The application results in coordinated special inspection among key power units near UHV transmission line in Henan power grid provide reference data and guiding advice for PFR comprehensive treatment and accident recovery of UHV transmission line tripping.

Key words: primary frequency regulation, evaluation method, UHV transmission line tripping, performance index, frequency regulation characteristics, coordination between gird and power source, accident recovery
