The present invention discloses a T-shaped mine high-voltage power grid automatic short-circuit calculation method based on topological coding. For network structure features of a mine high-voltage power grid, according to a connection relation between electrical devices in a mine high-voltage supply system and based on a device type and topological structure search, topological coding is performed for each device, a new T-shaped mine high-voltage power grid network topological model based on topological coding is provided to effectively achieve topology identification of a mine high-voltage power grid supply network; and on this basis, automatic calculation of a three-phase short-circuit current and a two-phase short-circuit current can be achieved based on the obtained topology analysismodel. The method is high in constitutive property, clear in analysis process and low in time complexity. 本发明公开了基于拓扑编码的T型矿井高压电网自动短路计算方法，该方法针对矿井高压电网的网络结构特点，依据矿井高压供电系统图中电气设备之间的连接关系，基于设备类型和拓扑结构搜索针对每个设备进行拓扑编码，提出种新的基于拓扑编码的T型矿井高压电网
