| 摘 要： | 传统上认为提高配电网运行电压可以降低线损。首先分析了线路损耗和运行电压之间的关系，并得出了以下结论：配电变压器处于重载运行时，提高运行电压可以降低线路损耗；配电变压器处于轻载运行时则相反。然后推导了确定最小线损运行电压的方法。最后通过现场试验验证了此方法的有效性和实用性。

| Abstract: | Traditional theory regards that line losses can be reduced by increasing running voltage in distribution network.Firstly,the relation between line losses and running voltage are analyzed in the paper and a conclusion is drawn that when the distribution transformer is under the condition of heavy-load operation,improving running voltage can decrease line losses while the result is opposite when the distribution transformer is under the condition of light-load operation.Then,the method of determining running ... |
