基于TOPSIS模型的智能变电站二次设备评估方法 Evaluation Method of Intelligent Substation Secondary Equipment Based on TOPSIS Model

智能变电站二次设备评估系统旨在基于数据库中的数据，根据专家系统中给出的评估方法对智能变电站二次设备的状况进行综合评估。本文根据智能变电站运行监测特征量，构建规范化决策矩阵，计算权重系数，建立TOPSIS评估模型并带入数据，根据评估指标得到智能变电站二次设备的状态评估结果。并根据实例分析，通过与模糊综合评估方法结果相比较，验证了基于TOPSIS模型的智能变电站二次设备评估方法的实用性与准确性。 Intelligent substation secondary equipment evaluation system aimed at evaluating status of intelligent substation secondary equipment based on the data in the database and evaluation methods given in expert system. Based on the characters of intelligent monitoring substation operation, standardized decision matrix was built and weight coefficient was calculated. TOPSIS evaluation model was set up so that the assessment results of intelligent substation secondary equipment condition can be acquired according to the assessment classification indexes. By instance analysis and comparison with the fuzzy comprehensive evaluation method, the practicability and accuracy of the evaluation method were proved.
