[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.
