Direct current system simulation operation evaluation method and system based on state logic

The invention provides a direct current system simulation operation evaluation method based on state logic. The method comprises the following steps: obtaining operation state change logic information in a simulation operation record; and comparing the obtained operation state change logic information with preset operation state change logic information for evaluation to obtain an evaluation result, wherein the operation state change logic is constructed according to a simulation operation record and a pre-established system equipment position state library, and the system equipment position state library comprises an equipment state name and a component position state corresponding to the state; and the evaluation operation state change logic information is determined by an initial state and a target state of the direct current power transmission system. The problem of sequential and non-sequential evaluation in the operation process is solved, no matter how simulation personnel operate, evaluation is perfor
