摘要

小负荷方式下系统的频率稳定形势日趋严峻。针对华东电网“9·19”事故，从负荷模型及调速器/原动机模型角度研究分析了影响华东电网频率响应特性的关键因素。基于实测数据，对华东电网负荷频率响应因子，机组的一次调频限幅、调差系数，以及锅炉主蒸汽压力模型相关参数进行了辨识，复现“9·19”事故的频率响应特性。根据辨识结果反映的问题提出了相关建议。

Abstract

The frequency security and stability situation in low load mode is worsening. The key factors which affect the frequency response are analyzed from the point of view of the load model

turbine-governors and drum boiler in the “9·19” incident. On the basis of measured values

the load frequency factor

the parameters of primary frequency modulation limit

frequency coefficient

and main steam pressure are identified. The results reflect the dynamic frequency trajectory of the “9·19” incident successfully. According to the results of reconstitution

relevant recommendations are put forward.
