The invention discloses a method and a system for processing task information. The method for processing the task information comprises the following steps: receiving description information for describing a hidden danger checking and controlling task of a power grid system through a first client side; generating the hidden danger checking and controlling task according to the description information and sending the hidden danger checking and controlling task to a second client side by the first client side; receiving and decomposing the hidden danger checking and controlling task by the second client side to obtain a plurality of sub tasks; respectively sending the plurality of the sub tasks to a plurality of third client sides by the second client side, wherein the plurality of the sub tasks are in one-to-one correspondence with the plurality of the third client sides; returning the implementation results of the plurality of the sub tasks to the first client side by the plurality of the third client sides. According to the method and the system provided by the invention, the problem that the task implementation results are difficult to timely obtain in the prior art is solved, so that the effect of timely obtaining the task implementation results are achieved.
