【摘要】：本世纪初,欧美发达国家着眼于保障能源安全和应对全球气候变化提出了智能电网的概念,2009年以来,广东电网公司相继编制了《绿色电网规划设计指导原则》和《绿色电网建设试点工作方案》,开展了“智能电网总体研究框架”及“智能配电网发展框架及体系研究”等工作,将智能配电网关键技术研究列为重点科技项目。其中,深圳坪山新区国家生物医药产业基地被确定为智能配电网试点建设起步区,是下一步智能电网项目提出、研究和建设的重要依据。深圳坪山新区起步区是国家生物医药产业基地,生物医药产业是深圳市大力鼓励和支持的三大新兴产业之一。准确的定位、良好的经济形势给坪山起步区电网的建设和发展提供了重大历史机遇,同时也提出了新的更高要求。本文从坪山新区经济社会发展特点出发,通过对坪山起步区电网的现状情况及在智能电网发展方面的优势、基础的分析,提出了坪山起步区智能配电网建设的总体目标和总体架构,阐述了坪山新区智能配电网试点建设的总体思路和发展目标,论述了工程的规划方案和关键技术措施。在一次系统规划方面,包括中压配网网架规划、分布式电源及储能系统规划、电动汽车充电规划,通过对比分析,中压配网网架推荐采用“三供一备”供电模式,分布式电源中容量较小的分散接入0.4kV配电网,容量较大的专线接入10kV配电网,储能系统推荐选择锂离子电池作为储能载体,规划电动汽车充电站1座和充电桩480个,充电站包括12台非车载直流充电机和2台变压器。在二次系统设计方面,包括高级配电自动化规划和高级用电计量系统规划,高级配电自动化采用两层(准三层)结构层次,即主站、通信子站和配电终端,推荐以深圳供电局配电主站为坪山新区配电自动化系统的主站,规划配置73套四单元型配电终端、73套接入层以太网设备、3套三层以太网设备、38千米光缆;高级用电计量系统采用光纤复合低压电缆的EPON组网方案,规划配置480台光节点计量设备,另外还对大型、中小型专变用户、充电站/桩、低压单相/三相工商业用户和居民用户计量模式进行了规划。
[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.
