摘要
针对高压、中压和低压配电网规划各自的特点,提出了相应的理论线损率估算方法。特别是对于结构复杂的中、低压配电网,引入了损失系数法和允许损失率修正因子法,最大限度地克服了规划态系统数据匮乏、负荷分布信息模糊等制约因素,为配电网规划工作提供了一种估算配网理论线损率的方法。算例表明了该方法的高效性和工程实用性。
Considering the features of high,middle and low voltage distribution network planning,the methods for estimating the energy loss rate are presented.Especially,regarding the complicated middle and low voltage distribution networks,a loss coefficient method and a factor correction method of allowable loss rate are proposed to overcome the problems of data deficiency of feeders and fuzzy load distribution information. A numerical example shows the method of energy loss estimation for distribution network planning is effective and practical.
