Method, device and equipment for determining design scheme of low-voltage topological relation analysis system

The embodiment of the invention provides a method for determining a design scheme of a low-voltage topological relation analysis system, and the method is characterized in that after starting password input operation of an electronic key is completed, whether identity information of the electronic key belongs to registration information of a client or not is recognized; under the condition that the identity information of the electronic key belongs to the registration information of the client, the number of target analysis items in a target analysis system is determined, the target analysis system at least comprises a topology function module, and the topology function module at least controls two target analysis items; determining the analyzed duration of each target analysis item; determining the target analysis item of which the analyzed duration is greater than or equal to a preset duration as a topology analysis target item; determining a topological relation type according to the type of the topologica
