摘　　要：为满足山东省用电的需要,计划2010年、2012年实施西北(宁东)—华北(山东)直流联网工程。该联网工程有利于优化资源配置、水火电互补运行,预计可取得显著的送电效益和诸多联网效益。但还要考虑到直流故障对山东电网带来的冲击。通过详细的潮流计算、暂态稳定计算,分析了2012年山东电网在有无交流特高压2种方式下直流故障的适应性。To meet increasing demand of power load in Shandong power grid, North West-North China DC Intereonneetion Engineering will be implemented in 2010, and in 2012. The intereonnection engineering can optimize resources, additionally, hydro and thermal generation will be complementary, and so the engineering can bring remarkable benefit on power delivery and many profits of grid connection. At the same time, the paper calculates impact of DC failure to Shandong power grid, and analyzes the DC failure adaptability in Shandong power grid in form ofUHV AC supporting or not in 2012.
