The invention discloses a method for scheduling broadband and narrowband hybrid service channel resources of a power wireless communication system, the method comprises the following steps of S1, dividing various services to be scheduled by a power wireless communication system into broadband services and narrowband services, and the scheduling priority of the broadband services being higher thanthat of the narrowband services; S2, before each scheduling period starts, calculating the scheduling priority of each broadband service, and allocating channel resources to each width service according to the priority; s3, if residual channel resources still exist after the resources are allocated to the broadband service, calculating a scheduling priority of the narrowband service and allocatingthe channel resources; and S4, transmitting the scheduled service according to the scheduling priority and the allocated channel resources. According to the invention, the requirement of low time delay of broadband services in a power system can be met, the fairness of resource allocation can be ensured as much as possible, and the power system can support broadband and narrow-band service transmission at the same time.
