考虑综合效益的低压配网台区无功补偿评估方法及其应用
摘要：目前低压配网台区无功补偿方案效益评估主要偏向经济效益而忽略电压质量问题,导致无功补偿方案优劣评估只考虑初始投资问题,本文提出了一种从电压质量及经济效益两个方面对低压配网台区无功补偿综合效益进行评估的方法。首先,建立电压质量指标体系并且对每一指标进行描述及定义,同时对无功补偿装置在使用过程中成本费以及节省的网损费分别进行评估,将产生净收益作为经济效益指标;然后,从无功补偿点和补偿容量两个维度设计不同的无功补偿方案并且对不同方案的综合效益进行比对;最后运用本文提出指标对实例进行分析,结果验证本文方法能够直观评估不同无功补偿方案综合效益优劣。
Abstract:The benefit evaluation for low voltage distribution network area mainly considers economic benefit and ignores the voltage quality problems, which results in the problem that the initial investment is only considered in reactive power compensation schemes. So in this paper, a comprehensive benefit method of reactive compensation for low voltage distribution network area is presented from two aspects of voltage quality and economic benefit. Firstly, index system for voltage quality is established and each index is described and defined. At the same time,the operation cost of reactive power compensation device and the saved network-loss cost are evaluated separately, which take net income as economic benefit index. Then, different compensation schemes are designed from two aspects of the reactive power compensation capacity and compensation site, and their comprehensive benefit are compared. In the end, examples are analyzed by using proposed indexes, and the results show the method can directly evaluate the advantages and disadvantages of comprehensive benefits for reactive compensation schemes.
