Abstract:

This paper expounds the construction scheme of smart grid for refining and petrochemical enterprises from the dimensions of necessity, objectives, technical route and implementation plan. It involves power grid planning and design, operation, dispatching, technological innovation and other fields. Firstly, it is analyzed that the development requirements of refining and petrochemical enterprises to build smart grid are to achieve safety, economy and low carbon. Secondly, based on the requirements, the objectives that must be achieved in building the enterprise smart grid are summarized, including the realization of a strong grid, a strong self-healing ability of the grid, green energy use, optimization of assets and operating efficiency and information security. Finally, the overall technical route of smart grid construction for refining and petrochemical enterprises is proposed —— “top-level planning, hierarchical implementation; information connectivity, collaborative empowerment”. At the same time, it is pointed out that standard first is of great significance to the construction of enterprise smart grid, and the system construction of enterprise standard is defined in a framework.

Key words: refining and petrochemical enterprise, smart grid, relay protection, self-healing function, green energy use, asset management, information security, technical standard
