摘　　要：提出了一种利用潮流Jacobian矩阵的最小奇异值δmin选择无功补偿节点的方法。文中给出了δmin对节点有功功率和无功功率以及并联电纳的灵敏度的计算公式,根据用灵敏度指标来选择无功补偿节点。用两个电力系统进行仿真实验,其结果表明了算法和设计的正确性和可行性。A method to determine reactive - load compensation nodes by the minimum singular value δmin in Jacobian load current matrix is proposed. The sensitivity calculation formulae of δmin for the active and reactive power of node and for parallel susceptance are presented. Thus, the compensation nodes cart be closen according to the sensisivity indexes. A simulation test of two power systems is carried out. The result shows the correctness and feasibility of the calculation and design.
