矿山工业大多地处偏远山区,都需要架设较长的专用输电线路。这样,线路损耗就成为一个不可忽视的问题,其中无功补偿就是一个必不可少的降耗措施。目前,由于地方小水电的蓬勃发展,一些矿山用电已部分地取自于这些小水电站区,这些发电设备发出的电力经过几十公里不等的距离并接在 Most of the mining industry is located in remote mountainous areas, all need to set up a longer dedicated transmission lines. In this way, the line loss becomes a problem that can not be neglected, among them the reactive power compensation is an essential consumption reduction measure. At present, due to the booming development of local small hydropower, some mines have partly taken power from these small hydroelectric power stations. The power generated by these power plants has gone through tens of kilometers of distances and connected
