偏远地区配电网容载比的算法改进模型
|
摘要
由于我国边远地区现状经济落后、负荷分散,容载比普遍偏高,并高于《城市电力网规划设计导则》(以下称《导则》)中推荐的1.8-2.1的取值范围。《导则》中给出了容载比计算的普适模型,但对偏远地区容载比的计算并不适用。介绍了一种容载比的算法改进模型。该模型在《导则》给出的容载比计算模型的基础上做出修正,充分考虑到偏远地区经济不发达、供电范围大、人口稀疏、负荷分散、网络损耗大等影响因素,使容载比的计算结果更契合当地的电网现状和用电水平,更好地指导电网规划和建设,对偏远地区电网的良性运行和长远发展有一定的参考价值。
In view of the economic backwardness,the scattered load,and the capacity- load ratio in remote areas is high,which is higher than the recommended ranges of 1. 8-2. 1 given by " urban power network planning and design guidelines"( hereinafter referred to as " Guidelines"). The guidelines introduce a pervasive capacity- load ratio model,but the model does not fit for remote areas. This paper describes an improved algorithm model for capacity-load ratio. On the basis of the original model,the optimization model takes into account the economic underdevelopment,large power range,sparse population,load balancing,large network loss and other factors. This improved capacityload ratio calculation model is given to fit the local situation and the electricity grid level and guide the planning and construction of the power grid,which provides some reference value to the healthy operation and long-term development of power grid in remote areas.
