The invention relates to a service information technology for data transmission in power distribution network services, in particular to a verb and noun based power distribution network service message flow generating method. The verb and noun based power distribution network service message flow generating method comprises the steps that information interaction verbs and nouns relevant with power distribution network application are formulated; 2, service subject layout is performed according to the specific power distribution network application, and message flows adopting transmission modes and directions are specified and formed; 3, message encapsulation is conducted on laid-out service subjects by combining with the verbs and nouns; 4, the step 2 and the step 3 are repeated till complete message flows are formed. The verb and noun based power distribution network service message flow generating method provides unified and standardized service message flows for application systems in a power distribution network, achieves power distribution network information interoperability and rapid and effective message transmission and later-period maintenance, solves the problems of low message transmission reuse rate and large-amount repeated system development, accordingly improves the information interoperability level and guarantees the continuity and stability of information power distribution network services.
