Distribution power application software（DPAS）is an important part of the distribution automation system.In view of the data interaction issues in the complicated environment of the system as well as distributed computing communication demand based on the data-level task decomposition，a communication architecture based on ZeroMQ message-oriented middleware is put forward.Meanwhile，a common message format is also designed to meet the practical communication needs.The excellent performance of ZeroMQ makes the computing platform able to rapidly access data in a heterogeneous environment.The distributed architecture can not only greatly improve the analysis speed of the advanced applications，but also make the system more robust.Deployed and tested in the real engineering environment in the distribution automation system（DAS）of Jinan，the feasibility of the communication architecture has been proved.
