| 中文摘要:变压器传统的离线监测方法只能得到变压器的整个运行阶段的平均损耗数据,为得到变压器损耗的实时数据,设计一种基于信息融合技术的变压器数据在线监测方法。首先建立电能损耗数值计算模型,体现出有功、无功、空载、负载损耗之间的关系,适用单向树搜索法来优选功率损耗最小的变压器并列运行方式,在有限的运行切换次数内最大程度减少损耗。在变压器的在线运行监测中,对数据采集器进行设计,利用信息融合技术对采集到的信息进行综合处理和协调优化,最终实验变压器的在线监测流程。通过模拟实验结果表明,设计的监测方法能够得到的变压器的实时损耗监测结果,且与常规方法相比误差能控制在10%以内,说明设计的方法具有一定的可靠性。 |

| Abstract:The traditional off-line monitoring method of transformer can only get the average loss data of the whole operation stage of transformer. In order to get the real-time data of transformer loss, an on-line monitoring method of transformer data based on information fusion technology is designed. Firstly, a numerical calculation model of power loss is established, which reflects the relationship between active power, reactive power, no-load and load loss. The one-way tree search method is applied to optimize the parallel operation mode of transformer with the minimum power loss and minimize the loss within the limited operation switching times. In the on-line operation monitoring of the transformer, the data collector is designed, and the information collected is comprehensively processed and coordinated and optimized by using the information fusion technology. Finally, the on-line monitoring process of the experimental transformer is carried out. The simulation results show that the designed monitoring method can get the real-time loss monitoring results of the transformer, and the error can be controlled within 10% compared with the conventional method, which shows that the designed method has certain reliability. |
