A Classification Rolling Contingency Screening Method for On-line Transient Security and Stability Assessment
摘要
Abstract
To meet the requirement of calculation time for on-line transient security and stability assessment,an on-line transient security and stability contingency screening method based on margin and mode estimation is proposed.According to the margin and modes information of each contingency in previous assessment results,including transient power angle stability, transient voltage security,transient voltage stability,and transient frequency security,and combining the power flow change, in service or out of service information of the relevant components associated with the security and stability modes of each contingency,the transient security and stability margin of each contingency under the new on-line transient security and stability evaluation is estimated,and the corresponding security mode is determined.Thereby,the contingency subset,which needed to be calculated in detail can be screened from the complete contingency set in the on-line transient security and stability evaluation.According to the simulation analysis of actual power network data,the validity and practicability of the proposed method can be verified.关键词
