At present, the application of power distribution automation system is more widely, usually adopt centralized automation solution. With the development of distribution network, the line is more complex, more control function, need to configure the more reasonable and more convenient and flexible function realizes the measurement and control terminals. Based on these considerations, this paper presents a ring main unit of distributed automation system solutions. This paper mainly do the following work:1. The traditional ring main unit centralized automation system were studied, and to deeply understand the actual site of power users for terminal power distribution automation system’s functional requirements, puts forward the ring main unit distributed automation system solution:(1) Ring main unit proposed the general structure of the distributed solution framework, including the hardware and software solutions, function, qualification fault self-healing scheme, communication scheme and scheme of power supply part has carried on the detailed explanation.(2) Analyzed the ring main unit distributed system controller and the overall structure of the main control unit. And its hardware structure and software function has carried on the analysis and research, proposed the implementation scheme of hardware and software.(3) Study the ring main unit controller and master the function of the unit. Mainly include three remote ring main unit and following the basic function such as insurance, include the auxiliary function of ring main unit and extended functionality.(4) For fault self-healing ring main unit qualify for detection method is analyzed, and the line fault self-healing control system’s overall structure and its components were studied.(5) Analyze the structure of optical fiber communication system principle, puts forward the communication system overall scheme, and analyzes the ring main unit controller and the communication function of the main control unit and network mode.(6) Power supply scheme is presented. Circuit is analyzed in accident cases using ring main unit power back-up power supply with PT.2. Combined with the actual ring main unit, the concrete application of distributed automation, adopts the ring main unit, terminal, distribution network automation and distribution network background monitoring center, three layers of design and the automation system, and feeder automation.line fault detection and handling aspects has carried on the narration, further confirms the feasibility of the scheme has a certain theoretical analysis and practical.This design can be the operation line of real-time acquisition data information, the ring main unit controller on line information accurate, its controller and the main control unit and the background monitoring center can exchange information through a communication network, to further improve the power supply reliability of power system, which adopts distributed ring main unit, power distribution automation solution will be more broad space for development.
