In order to work out effective black start schemes，the initial schemes should be provided during the establishment of black start. The depth first search strategy（DFS） integrated with rules is proposed to automatically form the black-start initial schemes. First， a number of effective rules are summarized according to the requirements and characteristics of the process of black start; then， by the topology connection of the power network built by the visual graph system， more concise initial schemes are found by the DFS with the help of the rules. An example shows that the proposed method for the automatic generation of black start schemes is effective and feasible.
