摘　　要：电力变压器是电力系统的枢纽设备,变压器运行状态直接影响电网的安全运行。及时掌握变压器的各项运行指标并加以分析,对变压器的状态检修工作以及电网的安全运行分析尤为重要。在着重分析影响变压器运行的各状态参量基础上,从实际应用出发,将现有主、客观赋权方法进行有效结合,确定各项运行指标在变压器运行状态评估中的权重,以建立电力变压器运行状态综合评判指标体系。通过对大量样本数据的分析及对现有成果的归纳,验证该状态评估方法的准确性,为变压器状态检修提供较为准确的理论依据。Power transformers are one of the important equipment in power system.Running status of power transformer directly affects safety of power grid.It is important for the condition-based maintenance of transformers and the safety analysis of the power grid according to in-time monitoring and analyzing of various operation parameters.Based on the state parameters of transformers and considering the practical application,we combine the subjective weighting and objective weighting to determine the weight of each index in the evaluation of the operation state of transformers.Analysis of the data and the results have shown that the weight for transformers condition is reasonable and satisfying.The results can provide a more accurate theoretical basis for transformer condition maintenance.
