Simulation Control Design of Function of Ring Main Unit in Distribution Network

Ring network cabinet is a group of electrical equipment that installs high-voltage switchgear in steel metal cabinets or assembles spaced ring network power supply units. Its core components are circuit breakers, load switches and fuses. The ring main unit is used for splitting and closing load current, breaking short-circuit current and transformer no-load current, charging current of overhead lines and cable lines at a certain distance, and plays the role of control and protection. It is an important switch equipment for ring network power supply and terminal power supply. In the modern smart grid, the ring main unit as the intelligent terminal of the distribution network has become an important part of the smart grid construction, and the research technology of the smart ring main unit has also attracted the attention of professionals. Scale of power system structure
