摘　　要：针对目前换流站位置的确定主要是从工程技术、经济和环境方面考虑且缺少理论分析的问题,从直流换流站选址对整个电力网络结构特性的影响入手,利用复杂网络理论分析不同的选址方案下整个电网所表现出的抗攻击性。通过对不同选址方式进行比较研究,找到电网结构上更坚强的换流站选址方案。得出以网络中度大的节点作为直流输电的连接点,将使得建成后的电网更具有无标度特性,即更坚强。并以IEEE14测试系统分析验证了所提方法的有效性。The current position determination for converter station is mainly based on the consideration of engineering technology, economy and environment, and is lack of theoretical analysis. Starting from the influence of DC converter position selection on the structure properties of the whole power grid, we use complex network theory to analyze the anti-aggressivity of the power grid with different position selection schemes. Through comparing different position selection schemes, the stronger scheme for converter position determination is found. It is concluded that taking the node with large degree as the connection point of DC transmission will make the established power grid have less scales, namely more stronger. The IEEE 14 test system analysis proves the correctness of the proposed method.
