摘　　要：单相负荷非侵入辨识技术已进入试点应用,而三相负荷的非侵入辨识研究尚处于萌芽阶段。针对三相空调负荷开展非侵入辨识研究,提出了一种基于多源特征量组的非侵入式空调辨识方法,并通过大量试验样本分析确定了判据的阈值,开发了基于多源特征量的非侵入式三相空调辨识算法,最后以五种电器多次混合运行的复杂工况为例进行三相空调负荷辨识分析。运行结果表明,三相家庭空调的启停时间辨识误差在5s以内,启停时刻的功率的辨识精度可达到85%,验证了辨识算法对三相空调负荷辨识的有效性和准确性,可以满足用户空调监测和友好互动管理的需求。Single-phase load non-intrusive identification technology has entered the stage of pilot application,but the research on three-phase load non-intrusive identification remains in its emerging phase.With regards to the research on non-intrusive identification of three-phase air-conditioning load,a non-invasive air conditioner identification method based on multi-source characteristic quantity was proposed,the threshold value of the criterion was determined,a non-intrusive three-phase air conditioning identification algorithm based on multi-source characteristic quantity was developed,and finally an identification analysis was made on three-phase air conditioning load,taking an example of complicated working conditions of mixed operations of five electric appliances.The operational results indicated that the error of identification of start-stop time of the three-phase household air conditioner remained within 5s,and the accuracy of identification of the power at the start-stop time could reach 85%,thus verifying the effectiveness and accuracy of the identification algorithm for the three-phase air conditioning load identification.The proposed approach could meet the requirement on monitoring and friendly interactive management of user air conditioners.
