“…(2) For each graph element, which is called graph element A, we obtain the connected line element according to the Links function in Visual Graph, and then find the graph element B at the other end of the line [12]. If the name of the foot of the connection between graph element A and the connected line element starts with "foot_ in", it means that graph element B is the child node of graph element A.…”

The current conventional oscillatory search algorithm for relay protection logic diagram is prone to fall into local optimum due to the late population diversity reduction, which leads to poor search results. In this regard, a sequential traversal-based oscillation search method for relay protection logic diagrams is proposed. The oscillation search algorithm is optimized by finding the second-order oscillation factor, optimizing the topology of the algorithm, and constructing the relay protection logic diagram model to obtain a library of graph elements. The experimental results show that the proposed oscillation search algorithm converges faster and has a more desirable search effect.
