摘　　要：以人工鱼群寻优思想为基础,提出了适用于输电网网架规划的人工鱼群算法。针对输电网规划的特点,定义了该算法的参数,给出了选取上述参数的原则和求取"距离"、"邻域"和"中心"的运算规则,制定了以觅食行为算子、聚群行为算子和追尾行为算子为基础的寻优策略。将N安全意义的启发式倒推策略运用到该算法中,加快了其收敛速度。2个算例的求解结果验证了该算法的正确性和有效性,表明该算法具有良好全局寻优能力和较快的收敛速度。Based on the optimization by artificial fish swarm, an artificial fish swarm algorithm （AFSA） suitable to transmission network planning is proposed. According to the features of transmission network, the parameters used in AFSA and their practical meanings are defined; the principle of choosing these parameters and the operation rules to solve distance, neighborhood and center are given; the optimization strategy based on preying behavior operator, swarming behavior operator and following behavior operator is worked out. By means of applying heuristic backward tactics of N safety analysis in the proposed AFSA, the convergence speed of the proposed AFSA is improved. The effectiveness and correctness of the proposed AFSA are verified by results of two calculation examples and it is indicated that the proposed AFSA possesses satisfied global searching ability and fast convergence speed.
