10KV配电网节能降耗措施研究

Research on Energy Saving Measures of 10KV Distribution Network

配电网是电力系统中功率消耗的主要部分,实现10kV配电网的节能降耗具有重要意义。10kV配电网的节能降耗包括变压器降耗和线路降耗两部分。变压器降耗可以通过保障变压器经济运行、推广节能变压器和进行无功补偿等方法解决。降低线路损耗可以通过提高线路截面积、缩短传输距离和降低三相不平衡度来解决。

The distribution network is the main part of the power consumption of the power system. Achieving the energy saving of 10kV distribution network has a graet meaning. The energy saving of 10kV distribution network include two parts：rerducing consumption of transformer and lines. Saving transformer consumption can be solved by ensuring transformer economic operation,promoting energy saving transformers and reactive power compensation. Reducing line losses can be solved by increasing the line cross-sectional area,shortening the transmission distance and reducing the phase imbalance.
