doi:10.11930.2015.11.88

摘要/Abstract

摘要： 针对目前一次调频性能评价方法不能准确描述所有一次调频过程的问题，提出特高压跳闸事故下的一次调频性能评价方法。通过对比正常情况下一次调频过程的统计结果，得出特高压跳闸事故下一次调频过程的特性。基于该特性构建新的性能评价指标体系，同时对原性能评价指标存在的问题进行补充完善。可对特高压跳闸事故后不同机组的一次调频动作过程进行精确的区分描述，并在河南电网环特高压重点电厂网源协调专项检查中得到应用，对一次调频的综合治理和特高压跳闸事故恢复提供数据参考和指导依据。

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
