摘要
电力变压器在系统中承担着功率传送、电压升降和电能分配和转移的重任,其运行状态决定了电力系统是否能可靠、安全、经济的运行。本文介绍了变压器状态评估的指标体系,提出了一套基于模糊评判模型的变压器状态评估的综合模型,最后通过实例验证了基于模糊综合评判模型的变压器运行状态评估方法的合理性和有效性。
Power transformer undertakes to the responsibility of Power transmission, voltage transformation, energy distribution and transfer in the power system, the normal operation of power transformer has an important rule for the system reliability, security and economic operation. The state evaluation index system is introduced briefly in the paper, Fuzzy Synthetic Evaluation model is used to evaluate the State Evaluation of transformer. Finally the example shows the evaluation method based on the fuzzy synthetic Evaluation model for the operation state of the transformer is reasonable and effective.
