摘　　要：文章以我国目前规划的２０２０年电网作为目标电网，通过大量的计算分析，研究和发现了我国未来大区电网互联可能存在的联网技术问题，如：大区电网互联可能会影响网架薄弱电网的网内安全稳定水平的问题，多个大容量直流线路集中落点带来的电压稳定问题，直流联网送受端电网的相互影响问题，交流一点联网和多点联网的问题，大区电网交流互联的潮流控制问题，大区电网互联的低频振荡问题，电网互联对短路电流的影响问题以及我国大区电网互联后可能存在的薄弱环节。在我国大区电网互联规划研究中，对上述技术问题要给予充分的注意。Based on the results of power system analysis, this paper deals with the technical problems, which probably occurs in Chinese interconnected power systems in future, such as the stability reduction in the weak grids of interconnections, voltage instability caused by a number of larger neighboring inverters, interaction between the sending and receiving system interconnected by HVDC, loop flow, power oscillation and short circuit current levels, etc. Some technical measurements are discussed.
