| Abstract: | The intuitive secondary circuits of relay protection in smart substation have been changed into ab-stract network data streams. Reasonable and appropriate safety measures must be taken during the extensionwith the consideration of the influence of new intervals on operation intervals. Based on analysis of mainte-nance mechanism for smart substation,the paper elaborates on relevant safety measures for 110 kV bus dif-ferential protection connection without power cut in smart substation extension;besides,it verifies correctnessof extension strategy and reliability of safety measures by the extension project of interval I and II of 110 kVXuelin line of 220 kV Wenjin substation. |
