【摘要】 针对电气网络中的环形拓扑,提出了一种新的优化追踪算法。在环形网络结构基础上,以有效功率方向为引导,进行拓扑分解与组合。通过串接式拓扑和桥形交叉式拓扑构造子图的讨论,揭示了拓扑死锁效应是因相互依赖关系造成的,因而引入分量交叉的优化追踪思想,并研究了追踪效率与追踪次序的相关性。利用子图监视哨实现了跳跃式追踪的算法流程。对某实际供电系统算例进行拓扑测试,表明优化追踪法比普通的全网追踪算法节省了234ms,效率提高了74.76%。中小规模系统算例和中大规模系统算例结果表明了所述方法的高效性。更多还原

【Abstract】 A new tracking optimization algorithm is proposed for ring topology of electrical networks.Based on ring network structure,the algorithm can be used to guide the calculation with effective power direction for topological decomposition and combination.Cascade topology and cross-bridge topology structure sub-graphs are discussed,and topology deadlock effect caused by interdependence relationship is revealed.Cross-component optimize tracking is introduced,and the relationship of tracking efficiency and tracking order is proposed.Then,algorithm process of leap-bound tracking is achieved by using sub-graph sentinel surveillance.Finally,topology tests of a practical power supply system show that the optimal tracking method has saved 234 ms in computational time as compared with the conventional whole network tracking approach.This shows a 74.76% improvement in computational efficiency.Simulation results of small-medium scale and medium-large scale system examples show that new method is efficient.更多还原
