Feasibility Study On 110kV Longhua 3C Green Intelligent Substation Construction Project

With the development of society and economy, the changing electricity demand, electricity customers for electricity supply put forward higher requirements for power quality, reliability of supply is also increasing, which gives the green grid intelligent building higher The planning and design requirements. Grid construction design is a leading design green intelligent substation construction will determine the level and technical level substation, substation construction of green intelligent system feasibility study, to form a reasonable green intelligent substation designs technologically advanced economy, substation construction is of great significance.The rapid development of the power grid, green intelligent substation is increasingly becoming an important part of power grid construction. In this paper, the feasibility study Qujing 110kV Longhua 3C green intelligent substation construction projects for the object, the use of advanced computer technology, communication technology, control technology, environmental protection equipment in terms of advanced intelligent technology, and consider land, energy, water, materials and protect the environment, reduce pollution and other factors, by optimizing the power grid solutions and electrical equipment selection, the positive application of energy-saving new technology and new equipment and new materials, the need for the construction of the station site selection, network access system solutions, construction detailed technical comparison of demonstration and feasibility study many aspects of the economy of scale, inlet and outlet planning, engineering and energy saving.Project Planning and Design Equipment transformers used in all electronic transformers, switch with automatic operation and configuration of the primary equipment on-line monitoring system, intelligent primary equipment to meet all requirements for evaluation. Secondary equipment station control layer is configured substation cockpit integrated monitoring and unified information platform, the spacer layer configuration station domain protective equipment, process equipment used together wisdom layer integrated device, AC-DC power supply system using integrated power systems, video and environmental monitoring system uses intelligent substation auxiliary control system, high degree of intelligence of the entire station. Transmission Line adhere to the principle of security, reasonable cost control, the use of environmentally friendly energy-saving materials, and strive to maximize the use of resources.110kV Longhua change to meet three-star 3C green intelligent substation standards evaluation system. Through investment estimates, economic evaluation, 110kV substation Longhua 3C smart green construction project is feasible.By Longhua 3C 110kV substation construction feasibility study smart green projects, we will intelligent, efficient, reliable, green and other ideas into the power grid projects, promote the construction and development of green 3C smart grid. With green intelligent substation continue to explore building a smart covering urban and rural areas, efficient, reliable and green grid will continue to show in front of us.
