基于双因素理论的电能质量敏感用户需求识别

准确识别电能质量敏感用户,明确服务对象,是电能质量增值服务顺利推进的重要保障。本文基于双因素理论,提出一种敏感用户电能质量需求识别方法。首先,提出了敏感用户优质电力保健需求和优质电力激励需求的概念,刻画用户对高电能质量的需求程度和有偿优质电力服务的购买愿望。其次,提出接入点的电压暂降水平、工业过程后果状态落差和工业过程免疫水平三个指标,度量用户的优质电力保健需求;提出银行贷款偿还率、年度电费缴纳比率和相对销售净利率三项指标,度量用户的优质电力激励需求。针对数据缺失的情况,采用符号数据,计算保健需求综合指标和激励需求综合指标。建立电能质量敏感用户识别坐标系,定性识别用户对优质电力的需求,明确优质电力服务对象。通过算例验证,所提方法具有较好的正确性和实用性。

Identification of the demand of Sensitive Users of Power Quality Based on Two-Factor Theory

It is important guarantees for the smooth advancement of premium power value-added services that accurate identification of sensitive users of power quality and clear service targets. Based on the two-factor theory, a method for identifying the demand of sensitive users of power quality is proposed. Firstly, the concept of hygiene demand and motivation demand for premium power of sensitive users is proposed, and the user"s demand for premium power and the purchase desire of premium power service are described. Secondly, three indicators of voltage sag level of access point, drop of consequence state of industrial process and immunity level of industrial process is proposed, to measure the hygiene demand of premium power of users; three indicators of bank loan repayment rate, annual electricity fee payment ratio and relative sales net interest rate is proposed, to measure the motivation demand of premium power of users. In the case of missing data, symbolic data is used to calculate comprehensive indicators of hygiene demand and comprehensive indicators of motivation demand. A coordinate system of identification of sensitive user of power quality is established, qualitatively identify the user"s demand for premium power, and identify premium power service objects. The example is verified by the example, and the proposed method has good correctness and practicability.
