【摘要】：输电断面集中体现了电网的薄弱环节,是系统运行监控的重点。从电力网络演化发展的局域特征出发,提出了一种融于层次分裂过程的多类型输电断面同步搜索方法。基于电网局域间联络线路拓扑连接弱功能作用强的特点,定义输电线路的电气耦合强度指标。通过反复移除电气耦合强度最大的输电线路来分裂电网,产生联络线簇。组合联络线簇搜索出不同类型输电断面,并基于电网局域内部连接稠密度的分布特性,提出最小局域用于判别分裂过程是否终止。IEEE39节点系统标准算例和某省网实际算例的结果表明,所提方法不依赖于人工经验,能够有效搜索出不同安全主题关注的不同类型输电断面。
[Abstract]:The transmission section reflects the weak link of the power network and is the key point of the system operation monitoring. Based on the local characteristics of the evolution and development of power networks, a synchronous searching method for multi-type transmission sections is proposed, which is integrated into the hierarchical splitting process. Based on the weak function of the topological connection of the local connection line, the electrical coupling strength index of the transmission line is defined. By repeatedly removing the transmission lines with the highest electrical coupling strength, the power grid is split and tie line clusters are generated. Combined tie-line clusters are used to search different types of transmission sections, and based on the distribution characteristics of the local connection density, In this paper, a minimum local method is proposed to determine whether the splitting process is terminated or not. The results show that the proposed method does not depend on artificial experience, as shown by the standard example of the IEEE39 node system and the actual example of a provincial network. It can effectively search different types of transmission sections with different security concerns.
