中文摘要:

随着智能化变电站的推广应用,电子式互感器成为了关口电能计量的重要枢纽设备,也是用户电量贸易结算的重要设备。针对电子式互感器电能计量贸易结算过程中设备、人为和管理等不同因素所引起的贸易风险,提出了一种基于主成分分析法(Principal Component Analysis, PCA)和层次分析法(Analytic Hierarchy Process, AHP)主客观相结合的电子式互感器电能计量贸易结算风险评估方法。首先,分析电子式互感器电能计量贸易结算的风险因子,并从设备可靠性、客观运行条件、企业管理水平等多方面提出了电子式互感器电能计量贸易结算风险综合评价指标；其次,为求取指标赋权值,提出了一种PCA和AHP相结合的主客观赋权方法,即先采用PCA提取电子式互感器电能计量贸易结算风险综合评价指标的主成分指标,然后针对所提取的主成分指标采用AHP进行赋权求值,从而在不影响综合评估效果的前提下,大大减少综合评价的计算量；最后,通过天津典型的实际案例分析,验证了所提综合评价方法的可行性。

英文摘要:

With the application of intelligent substation in smart gird, electronic instrument transformer has become an important hub of energy metering equipment, and is the important device of user’s power trade settlement. In order to deal with the risk in the process of electricity metering trade settlement for electronic transformer caused by different factors, such as equipment, human and management and so on, it proposed the risk assessment method of electricity metering trade settlement for electronic instrument transformer based on principal component analysis and analytic hierarchy process. Firstly, it analysis the risk factors of power metering trade settlement for electronic transformer, and the comprehensive evaluation indexes of power metering trade settlement for electronic transformer is put forward from the third aspects of equipment reliability, objective conditions and management level of the enterprise. Secondly, an objective and subjective weighting method is proposed to combine principal component analysis method with analytic hierarchy process. It first extracts the principal component index of comprehensive evaluation indexes of power metering trade settlement for electronic transformer by principal component analysis method. Then, it uses the analytic hierarchy process to determine the weight of the evaluation indexes, according to the extracted principal component indexes. It greatly reduces the computation for the evaluation without affecting the comprehensive evaluation of the premise. Finally, a typical actual case verifies the feasibility of the proposed comprehensive evaluation method in Tianjin City.
