The invention discloses an intelligent operation and maintenance power distribution and utilization system based on an active service management mode. The system comprises an information concentrator(1), a total residual current protection circuit breaker (2), a middle-stage residual current protection circuit breaker (4), an intelligent electric meter (6) and a final-stage residual current protection circuit breaker (8). The total residual current protection circuit breaker (2) can be embedded into an HPLC single-phase carrier wave module, and an HPLC single-phase carrier wave is used in a plug-and-play mode and serves as a child node of an HPLC network, wherein the hierarchical relationship of the child node in the whole HPLC network and the like can be sensed by a route, and thereforethe network topology of the whole HPLC can be drawn. The middle-stage residual current protection circuit breaker (4) comprises a wireless and carrier wave dual-mode communication module (5), the datainformation from the middle-stage residual current protection circuit breaker (4) to the information concentrator (1) is transmitted by carrier communication, and the data information from the final-stage residual current protection circuit breaker (8) to the middle-stage residual current protection circuit breaker (4) is transmitted by wireless communication.
