With the expansion of the scale of power grid

the rapid growth of the quantity of data acquiring

and tasks of data processing and analysis as distributed in different nodes

the existing single-node task management technologies face serious challenges in making distributed tasks efficient and steady. This paper proposes a distributed task management technology for power grid dispatching and control systems. First

the demand of distributed task management for power grid dispatching and control systems is analyzed. Then the whole architecture

key technologies(including automatic deployment

load balance

redundancy fault-tolerance)

and typical applications are described. Finally

the test results show that the proposed technology is efficient and steady.
