The invention discloses a large power grid safety and stability intelligent evaluator device and an evaluation method. The method comprises the steps of obtaining power grid operation data; performing classification processing on the power grid operation data to obtain static parameter data and dynamic parameter data; performing static evaluation and decision based on the static parameter data to obtain a static evaluation and decision result; performing transient evaluation and decision based on the dynamic parameter data to obtain a transient evaluation and decision result; performing correlation analysis based on the power grid operation data to obtain a correlation analysis result; and performing visualization processing on the static evaluation and decision result, the transient evaluation and decision result and the correlation analysis result. The comprehensive utilization efficiency of core knowledge of a power system can be promoted, the safe and stable operation state of the power grid is comprehens
