摘要

电力系统的发展使许多老旧的输电线路仍在使用。这些传输线的维护成本越来越高。自从这些线路最初建成以来,已经建造了额外的新输电线路,以满足预测的未来需求。如果使用这些新线路而淘汰旧线路,传输能力将得到更充分的利用,维护费用将下降。随着电网的进一步发展,潮流的重新布线和旧线路的淘汰将得到优化。电力流的改道会对整个系统产生影响。连接到旧线路的一代提供的服务可能会减少。本文提出了一种量化重新布线潮流的技术和经济影响的方法,同时也解决了网络中新的和正在出现的问题。作为一个案例研究,对塔斯马尼亚州一组发电机和一个大负荷之间的一些旧线路退役的影响进行了分析。

Determining the technical and economic impact of reconfiguring a transmission system
Evolution of the power system has left many older transmission lines in service. These transmission lines are increasingly expensive to maintain. Since these lines were originally built, additional new transmission lines have been built with capacity for forecasted future requirements. If these newer lines are used and the older lines decommissioned, the transmission capacity would be more fully utilized and maintenance expenditure would drop. Re-routing of power flows and retiring of old lines is to be optimized with further development of the network. Re-routing of power flows has an impact on the wider system. Services provided by generation connected to older lines may be reduced. This paper proposes a method of quantifying the technical and economic impact of re-routing the power flow while also addressing new and emerging issues in the network. As a case study the impact of decommissioning some older lines between a group of generators and a large load in Tasmania is analysed.
