Abstract

The invention belongs to the electric power equipment technology field and especially relates to a multifunctional intelligent station integrating transformation, charging and conversion. And specifically, the invention relates to an intelligent transformer station and an electric automobile charging station, and the integrated multifunctional intelligent station possessing transformation, charging and conversion functions. The multifunctional intelligent station of the invention mainly comprises: a transformer substation system, a charging system and a communication monitoring system. The transformer substation system is connected with the charging system. The communication monitoring system constructs Ethernet through a fiber to realize communication with the transformer substation system and the charging system and monitoring the transformer substation system and the charging system. By using the multifunctional intelligent station of the invention, construction and investment costs of an electric automobile charging station distribution transformer can be directly saved. The construction and investment costs are small. A whole construction area of the transformer station and the electric automobile charging station can be directly reduced. Building land acquisition demands can be directly reduced. Information sharing in the intelligent station can be realized. Levels of automation, informatization and intellectualization of the intelligent station are high. The multifunctional intelligent station is suitable for dense population areas in cities and the areas where land expropriation is difficult, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a multifunctional intelligent station integrating charging and switching. Specifically, it involves smart substations and electric vehicle charging stations, and is an integrated multi-functional smart station with both charging and switching functions. Background technique [0002] As the global resource crisis and environmental pollution problems have become increasingly prominent in recent years, building a strong and reliable smart grid, actively accepting renewable and clean energy, and promoting the development of energy-saving and environmentally friendly electric vehicle industries have become the main ways for countries around the world to effectively respond to environmental and resource crises. With the State Grid Corporation officially proposing a strong smart grid development strategy in 2009, my country's smart grid construction work officiall...
