The invention relates to a quick starting and vector calculation method for intelligent substation integrated protection, which belongs to the technical field of electric system protection and control. The method comprises the following steps: carrying out quick starting and vector calculation for a protection object 1; judging whether the protection object 1 carries out secondary starting or not, if so, carrying out protection processing according to the result of the vector calculation, judging whether faults occur, and taking corresponding measurements, otherwise, carrying out the quick starting and the vector calculation for a protection object 2; and in such a way, carrying out the quick starting and the vector calculation for a protection object m, and judging whether the protection object m carries out secondary starting or not, if so, carrying out protection processing, otherwise, terminating the quick starting and vector calculation. According to the quick starting and vector calculation method, the CPU resource can be flexibly utilized, so as to achieve an effect that an integrated protection platform has better stability, reliability, openness, scalability and maintainability.
