基于优化网架结构的配网改造实用化措施

针对南宁供电局配网网架结构存在的问题,结合实际情况,探讨网架结构优化方法。在避免大规模停电及道路开挖的前提下,通过在分支线路加装开关、从线路末端进行环网、调整开闭所和箱式变压器接线方式等手段对配网结构进行优化、调整。改造后配网可靠性指标得到提升。在停电计划管控以及市政开挖限制日趋严格的大环境下,对配网网架结构分析后,选择恰当的位置进行配网局部改造和环网工程,将有利于提升配网可靠性指标。

Practical Measures of Distribution Network Modification Based on Network Structure Optimization

Aiming at problems in the distribution network structure in Nanning power supply bureau, the optimization of network structure is discussed based on the practical situation. Under the precondition of avoiding large scale outage and road excavation, measures such as adding switch at branch line, making the loop at the end of the line, adjusting connection mode of switching station and box type transformer and so on are taken to optimize and adjust the structure of distribution network. The reliability index of distribution network is improved after the modification. Under the big circumstance of increasing strict management and control of outage plan and limitation of municipal excavation, local modification of distribution network and looped network project in proper position after the analysis of distribution network structure is benefit to the improvement of reliability index distribution network.
