从配电网降损措施分析比较看合理配电模式

配电网降损采取的常用措施有：采用节能型变压器，提高负荷点功率因数，增大导线截面等。本文通过比较，发现尽管采取以上措施短期内对降低配电网损耗、提高电压质量有一定好处，但在现有配电模式下满足负荷发展的能力差。究其原因在于现有配电模式中配电变压器供电范围过大，低压线供电半径过长。改变现有配电模式，采取变压器小容量、多布点、缩短低压线供电距离的供电模式比采取上述降损措施更具优越性，且能较好的满足负荷发展的需求。

STUDY ON REASONABLE DISTRIBUTION MODEL BASED ON ANALYSIS AND COMPARISON OF METHODS FOR REDUCING THE LOSS

In this paper,the common methods for reducing the loss of distribution network is analysed.Although they are of benefit to reducing the loss and improving the voltage quality,they can't meet the increase of the load.The reason is that the transformer supply area is too broad and the low-voltage line is too long in present distribution model.Shortening low-voltage line and placing the transformers near the load is better than common methods for reducing the loss and meet the increase of the load.
