The invention discloses a black-start ADM (aid in decision making) supporting/training system and a method thereof. The black-start ADM supporting/training system and the method thereof solve the problems of deficiency of effective ADM tools under the condition of blackout of the prior power system, formulation of a system recovery proposal only by experience and incapability of being suitable for the current electric network requirements, and have the advantages of simple structure, convenient use, high automation degree, capability of effectively aiding in decision making for dispatchers and so on. The invention is characterized in that: the black-start ADM supporting/training system adopts a C/S architecture and consists of a black-start console module and a black-start computing server, wherein, a black-start console is a functional module which is extended on the basis of a DTS function, provides a user interface of the black-start decision supporting system, and utilizes the DTSfunction to exhibit and simulate a black-start proposal for achieving the aim of training the dispatchers; the black-start computing server comprises a proposal generation module, a proposal checkoutmodule and so on and can generate a black-start operation sequence proposal by utilization of an intelligent search algorithm according to power failure areas and quickly verify the proposal.
