设备侧电压暂降严重程度评估方法研究
|
摘要
综合考虑ITIC曲线、SEMI曲线和C4.110工作组提出的敏感设备耐受曲线,基于严重程度函数单调性和连续性的实际分布特征,分别建立了单相、两相和三相电压暂降影响度函数;在此基础上考虑电压暂降非矩形实测波形,利用多暂降阈值描述改进影响度函数,从而提出了一种考虑电压暂降类型与多暂降阈值描述的多暂降阈值设备侧电压暂降严重程度评估方法,该评估指标综合考虑设备耐受曲线及电压暂降事件的持续时间、暂降幅值、暂降类型和暂降波形评估严重程度。实例分析验证了所提方法的正确性。
Comprehensively considering the ITIC curves,SEMI curves and the tolerance curves of sensitive equipment proposed by C4.110 working group,the influence degree function of single-phase,two-phase and three-phase voltage sag are established respectively based on the actual monotonous and continuous distribution of severity function. On this basis,the non-rectangular waveform of voltage sag is taken into consideration,and the multiple sag threshold is used to describe the improved influence degree function,then a multiple sag threshold method considering the type of voltage sag and the tolerance characteristics of equipment is proposed to evaluate the severity of voltage sag on the equipment side of the actual system,and its evaluation indices comprehensively consider the equipment tolerance curve,the voltage sag duration,magnitude,type and waveform. Case study shows the correctness of the proposed method.
