摘要: |
为了定量评价电能计量设备的运行质量,并提高电力用户用电计量的准确性和可靠性,提出了一种联合采用CRITIC法和理想点法的计量设备运行质量评估方法。首先,基于电力信息采集系统中的电能计量设备运行监测大数据,定义了5个衡量电能计量设备质量的评估指标。然后,采用基于熵权和斯皮尔曼等级相关系数的CRITIC法确定电能计量设备质量评估指标的客观权重,并构建了基于理想点法的电能计量设备质量评估模型。最后,以浙江省宁波市某地区的电能计量设备运行监测数据为例对所提出的模型和方法进行了验证。验证结果表明,提出的方法不仅能够量化评价电能计量设备的运行质量,而且能够合理地评估出电能计量设备的优劣。 |

Abstract: |
In order to evaluate the operating quality of metering equipment quantitatively and improve the accuracy and reliability of the metering on power consumers, a method for evaluating the operating quality of metering equipment is presented by integrating the Criteria Importance Through Intercriteria Correlation (CRITIC) method with the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method. First, based on the metering data from the acquisition system for power consumers’ information, five indexes for evaluating the quality of electricity energy metering equipment are defined. Then, the CRITIC method based on the entropy weight and Spearman rank correlation coefficient is presented for determining the objective weight of each index, and an evaluation model of the quality of metering equipment is built based on the TOPSIS method. Finally, the actual data measured for electricity energy metering equipment in regional Ningbo power grid of Zhejiang province is served for validating the proposed model and method. The simulation results show that the proposed method could quantify the operating quality of metering equipment and evaluate metering equipment reasonably.
