摘　　要：阐述了配电网重构数学模型、二进制粒子群算法、量子编码的基本理论,对量子粒子群算法配电网重构进行了研究,将量子编码应用到离散粒子群算法中,用量子比特概率表示离散粒子的状态,根据二进制粒子群速度更新公式更新粒子的状态,改变开关开合状态进行网络重构。量子比特概率能够表征丰富的信息量,保证粒子的多样性和全局搜索能力。通过2个算例验证,表明量子粒子群算法满足了实际运行要求。This paper introduces the mathematical model of distribution network reconfiguration,binary particle swarm optimization algorithm and the basic theory of quantum coding,studies distribution network reconfiguration by quantum particle swarm optimization algorithm,adopts quantum coding in discrete particle swarm optimization algorithm,represents the state of discrete particle by the property of quantum dot,updates particle state on the basis of binary particle swarm speed and reconfigure distribution network by switch.The property of quantum dot is able to present rich information and guarantee the diversity of particle and global search.The two examples,given in the paper,show that this method meets the requirements of actual operation.
