摘要
提出了基于全寿命周期成本(LCC)理论的配电网电压偏差治理措施的优化方法。介绍了该方法的流程,构建了配电网工程改造的LCC分解模型,并利用现有的统计数据得出了主线换径、无功补偿及调整变压器分接头3种常用电压偏差改善措施的LCC计算模型。以某10 kV馈线为例,对其进行了供电电压偏差评估、改善方案制定及基于LCC理论的改善方案优化,方案确定为优先选择将变压器分接头档位提高一级,并在变压器二次侧加设无功补偿电容器。
A method based on LCC（Life-Cycle Cost） theory is proposed to optimize the countermeasures against the voltage deviation of distribution network. Its flowchart is introduced and the LCC decomposition model is established for distribution network reconstruction. The LCC calculation models are built based on the existing statistical data for three widely-used voltage deviation countermeasures：increase the conductor diameter,compensate the reactive power and adjust the transformer taps. As an example,the voltage deviation of a lOkV feeder is estimated and its countermeasures are planned,which is then optimized by the proposed method. The optimized measures are：set the transformer tap one level higher and install additional capacitors at the secondary side of transformer for reactive power compensation.
