1基于发电机对暂态势能集的电力系统暂态稳定快速评估显示文摘基于传统暂态能量函数方法,以简单3机3节点系统推导出一种基于发电机对暂态势能的系统暂态势能函数表达式。该暂态势能计算函数不需要全系统的网络拓扑参数或故障位置信息,仅需实时采集系统中少量的发电机机端电气状态量,计算方法简单有效。基于该发电机对暂态势能定义了受扰严重机组判别指标集,利用该指标的聚集特性在故障清除后极短时间内辨识系统的主导失稳模式,根据临界机组分群结果采用EEAC法快速计算当前故障模式下的系统暂态稳定裕度。IEEE 3机9节点、新英格兰10机39节点系统、某省级实际电网算例结果验证了该方法的正确性和有效性。苟竞 刘俊勇 Gareth Taylor Christopher Saunders 刘友波 刘洋 2015电网技术2015,39,2:16
2一种基于发电机对相对能量的电力系统临界机群快速辨识方法显示文摘准确辨识临界失稳机组是暂态稳定分析的关键。该文在推导基于发电机机组对的相对暂态动、势能函数基础上,根据机组对在故障切除时刻和故障切除后两个时步内的相对能量聚集特性,采用两阶段聚类分群算法,对故障切除后极短时间内系统的临界机群进行了辨识。由于相对能量函数的计算不依赖于全系统的网络拓扑参数或故障位置信息,仅需实时采集系统中少量的发电机机端电气状态量,减小了因候选集合漏选重要机组带来的辨识误差,且计算相对简单,缩短了辨识时间。新英格兰10机39节点系统、IEEE 145节点系统算例结果验证了该方法的正确性和有效性。苟竞 刘俊勇 魏震波 Christopher Saunders Gareth Taylor 刘友波 2015中国电机工程学报2015,35,24:11
