摘　　要：由于主变压器谐波损耗会造成电力资源的大量浪费,并影响其他设备的正常使用。为此,提出一种基于建筑信息模型(Building Information Modeling,BIM)全寿命周期的新型电力系统主变压器谐波损耗预警方法。从铁芯谐波损耗和绕组谐波损耗两方面展开对主变压器谐波损耗的计算;按照相关标准设定谐波损耗预警值,分析影响主变压器谐波损耗的各项影响因子,当谐波损耗值达到预警值时发出相应的报警提醒。通过与其他方法展开对比实验测试,结果表明,所提方法计算得到的主变压器谐波损耗值最接近实际值,与预警值比较后即可发出精准的预警提醒。The harmonic loss of the main transformer will cause a large waste of power resources and affect the normal use of other equipments.Therefore,an early warning method for harmonic loss of main transformer in novel power system based on the whole life cycle of building information modeling(BIM)is proposed.The harmonic loss of the main transformer is calculated from the two aspects of core harmonic loss and winding harmonic loss.The harmonic loss warning value is set according to the relevant standards;the factors that affect the harmonic loss of the main transformer are analyzed,and the corresponding alarm is sent out when the harmonic loss reaches the warning value.Through comparative experimental tests with other methods,the results show that the harmonic loss value of the main transformer calculated by the proposed method is the closest to the actual value,and can send out accurate warning alerts after comparing with the warning value.
