摘要:

为克服传统评估方法无法挖掘台区线损潜在影响因素、可靠性不高的缺点,提出一种基于数据驱动的台区线损评估方法。获取台区线损的10个影响因素,将其分为固有属性及运行属性两大类评估指标;采用正交信号校正法(OSC)剔除影响因素与台区线损的正交分量,作为灰色关联分析(GRA)的比较序列,并求取评估指标对台区线损的权重贡献。以10个A级供电台区作为算例,使用GRA、OSC-GRA、AHP-FA 3种算法对台区线损进行评估,结果表明基于OSC-GRA的台区评估方法在挖掘台区线损影响因素的潜在关系方面,以及进行排序评估方面具有最高的准确度。

Abstract:

In order to overcome the shortcomings that the traditional evaluation method can not tap the potential influencing factors of the line loss in low voltage station area,and the reliability of the line loss evaluation is not high,a line loss evaluation method based on data-driven is proposed.The 10 influencing factors of the line loss of low voltage station area are obtained,and divided into two categories of evaluation indicators of inherent attributes and operating attributes.The orthogonal signal correction method (OSC) is used to remove the orthogonal components of the influencing factors and the line loss of the low voltage station area,and the comparison sequence of gray relation analysis (GRA) is used to obtain the weight contribution of the evaluation index to the line loss of the low voltage station area.Taking 10 A-level power supply stations as an example,GRA,OSC-GRA,AHP-FA three algorithms are used to evaluate the line loss of the low voltage station area.The results show that OSC-GRA has the highest accuracy in digging the potential relationship between line loss influencing factors and performing ranking evaluation.

Key words: low voltage station area, orthogonal signal correction (OSC) method, gray relation analysis (GRA), line loss evaluation
