【摘要】 事故扫描可以大大减少需分析的预想事故数目,是在线动态安全评估的重要组成功能。文章定义了反映事故严重程度的多个性能指标,并综合这些性能指标提出了以滤除电力系统的不严重事故为目标的事故扫描的综合性能指标法。该方法滤除系统不严重事故的准确性较高,计算速度快,可以满足在线动态安全评估快速性的要求。更多还原

【Abstract】 Contingency screening is one of the most important functional modules of online dynamic security assessment, which can greatly reduce the quantity of predefined contingencies to be analyzed. The authors define several performance indices reflecting the severity of contingencies. With these performance indices integrated, an integrated performance index method, in which the harmless contingencies of power system are filtered, is proposed. The proposed method can filter harmless contingencies correctly and quickly and can meet the requirement of quickness of online dynamic security assessment.更多还原
