Capacity Enhancement, Energy-Loss Reduction and Voltage Control for Remote Three-Phase Distribution Feeders Supplying Electrical Power to Single-Wire Earth-Return Systems

向单线回地(SWER)系统提供电能的长配电馈线是澳大利亚电力网络中独特的子系统。SWER系统本质上是不平衡的，并且使用高阻值的导体，从而导致高能量损耗。这些系统的资本成本很高，因为负载的面密度很低，而且系统面临着不断增加的负载的挑战。将开发新的方法来平衡负载、控制网损和提高电能质量。将对新技术与送料器的改造或增强进行比较。预计将产生可观的经济和温室气体排放效益。

Long distribution feeders supplying electrical energy to Single-Wire Earth-Return (SWER) systems are unique sub-systems of the electric power network in Australia. The SWER systems are inherently unbalanced and use conductors with high resistance values resulting in high energy losses. The capital costs of these systems are high due to the low area density of loads and the systems are challenged by increasing loads. New methods will be developed for load balancing, controlling losses and improving the power quality. Comparisons will be made between the new technologies and the reconstruction or augmentation of the feeders. It is expected that substantial economic and greenhouse emission benefits will result.
