摘　　要：针对传统邻接矩阵在进行多个节点的电网拓扑分析时存在矩阵计算量大、效率偏低且难以满足实时性要求等问题,文中提出了一种基于融合邻接矩阵的多时态局域电网拓扑分析技术。该技术在将电网模型抽象为映射图的基础上,建立与映射图对应的邻接矩阵,通过该矩阵计算相应的全连通矩阵。同时为了提高计算效率,还在计算全连通矩阵的过程中引入了准平方的思想,并在每计算出一个新的连通矩阵元素后,使用该元素更新老元素及其对称位置元素的值,以得到全连通矩阵,从而完成电网拓扑中的母线与电气岛分析。测试结果表明,在相同的实验条件下,所提方法的运算次数相较于其他算法减少了60%以上,且运算时间大幅缩短。ing the power grid model into a mapping map,this technology establishes the adjacency matrix corresponding to the mapping map,and calculates the corresponding full connection matrix through the adjacency matrix.In order to improve the calculation efficiency,the idea of quasi square is introduced in the calculation of the fully connected matrix.After each new connected matrix element is calculated,it is used to update the value of the old element and its symmetrical position element,and finally the fully connected matrix is obtained,thus completing the bus analysis and electrical island analysis in the electrical network topology.The test results show that under the same experimental conditions,the operation times of the proposed method are reduced by more than 60%compared with other algorithms,and the operation time is greatly shortened.
