中文摘要	建设抗灾型的电力系统,首先要提高部分电网的设计标准,强化骨干战略通道的建设;其次是电源规划的合理布局。文中分析了恶劣气候条件对输电线路的影响机理,分别采用Brostrm载荷模型和改进模型计算并分析其冰力载荷。由于冰力载荷对线路停运率的影响最大,其准确性尤为重要。考虑风力载荷、冰力载荷和线路潮流水平对输电线路停运率进行模糊建模,从而得到恶劣气候和极端恶劣气候条件下系统的可靠性水平。以5节点简单2区域系统为例,对电源分层分区的合理布局和提高关键断面的设计标准2种规划方案进行优化求解,并分析2种抗灾型电力系统设计方案对规划结果的影响。; To construct the disaster resistance of a power system,firstly,power grid design criterion should be improved to strengthen the key transmission corridors;secondly,generation planning of power supply should be properly located.The impact of adverse weather on a power grid is discussed.Brostrm model and the improved model are proposed and used to study the transmission line ice load.The accuracy of ice load calculation is the key point because it affects the line outage rate much more than other factors.A fuzzy inference system is built to model the relationship between line outage rate and the three logic variables(wind load,ice load,and line flow level).Power system reliability is assessed under the conditions of adverse weather and extreme adverse weather conditions.Two design strategies on disaster resistance power system are tested in a five-bus two-area system,one is for improvement of power grid design criterion,and the other is for proper placement of planed generations.These two strategies have different impacts on system planning results.; 国家自然科学基金优秀国家重点实验室专项基金资助项目(50823001); 国家重点基础研究发展计划(973计划)资助项目(2004CB217908)~~
