摘要
Abstract
Along with the connection of distributed generation （DG）, the distribution network tunas from the network with single power supply to that with multi power supply, so primary protective relaying will be greatly impacted. On the basis of presenting the setting principle of current protection for traditional distribution network and taking a 35kV distribution network containing DG for example, the impacts of penetration level of DG and the position where the DG is connected to distribution network on key variables in the setting of traditional three-stage current protection are deliberated, besides, the adaptability of the conditions by which the protection are set under the two conditions, i.e., the variation of allowed penetration level of DG under the fixed network-connected position and the change of network- connected position under the fixed penetration level of DG, is emphatically analyzed, thus the allowed penetration level of DG for distribution feeder under a certain network-connected position and the scheme to choose the network-connected position under a certain penetration level of DG are quantitatively researched.关键词
