[Abstract]:At the beginning of this century, European and American developed countries put forward the concept of smart grid in order to ensure energy security and deal with global climate change. Since 2009, Guangdong Power Grid Company has worked out the guiding principles of Green Power Network Planning and Design and the pilot Project of Green Power Grid Construction, and has carried out the work of "General Research Framework of Smart Grid" and "Framework and system Research of Smart Distribution Network Development". The key technology research of smart distribution network is listed as the key science and technology project. Among them, the National Biopharmaceutical Industry Base of Pingshan New District of Shenzhen has been designated as the starting area for the pilot construction of smart distribution network, which is the important basis for the next smart grid project to be put forward, studied and constructed. The starting area of Pingshan New area of Shenzhen is the national biomedical industry base, and the biomedical industry is one of the three new industries encouraged and supported by Shenzhen City. Accurate positioning and good economic situation provide a great historical opportunity for the construction and development of power grid in Pingshan starting area, and at the same time put forward new and higher requirements. Starting from the characteristics of economic and social development in Pingshan New area, this paper analyzes the current situation of Pingshan starting area and its advantages in the development of smart grid. This paper puts forward the overall goal and framework of the intelligent distribution network construction in Pingshan starting area, expounds the general idea and development goal of the pilot construction of the intelligent distribution network in Pingshan New area, and discusses the planning scheme and key technical measures of the project. In the aspect of system planning, including middle voltage distribution network planning, distributed power generation and energy storage system planning, electric vehicle charging planning, through comparison and analysis, the medium voltage distribution network frame recommends "three supply and one standby" power supply mode. In the distributed generation, the smaller capacity is distributed to 0.4kV distribution network, the larger special line is connected to 10kV distribution network. Lithium ion battery is recommended as the energy storage carrier in the energy storage system. One charging station and 480 charging piles for electric vehicles are planned. The charging station includes 12 non-vehicle DC chargers and 2 transformers. In the aspect of secondary system design, it includes advanced distribution automation planning and advanced metering system planning. The advanced distribution automation adopts two layers (quasi-three layers) structure, that is, main station, communication substation and distribution terminal. It is recommended that the main distribution station of Shenzhen Power supply Bureau be the main station of distribution automation system in Pingshan New area, and 73 sets of four-unit distribution terminals and 73 sets of access layer Ethernet equipment and 3 sets of three-layer Ethernet equipment should be arranged. The advanced electric metering system adopts the EPON network scheme of fiber-optic composite low-voltage cable, and plans to configure 480 optical node metering equipments. In addition, it is also suitable for large, small and medium-sized special transformer users, charging stations / piles, Low-voltage single-phase / three-phase industrial and commercial users and residents of the user measurement model was planned.
