工业园区66kV变电所设计 摘 要 台安县位于中国东北辽宁省的中部、位于辽河三角洲腹地。交通发达，它拥有环渤海经济区和东亚经济圈的区位优势，被称为辽河平原的鱼米之乡。工业园建设实施于2001年，到现在，已经变成一个具有完备功能的经济发展增长区与开发先导区。本设计的电力负荷资料是依据于鞍山市台安县的工业园区，设计了该园区66kV变电所。设计具体内容包含：变压器选择和负荷计算、短路计算和高压电气设备的选取、设计接线、继电保护、变电所的布置等内容。本设计以实际电力负荷为根据，以让变电所运行在最佳状态为基础，根据有关规范与规定，完成对66kV变电所的设计。本设计首先进行变电站变压器的电力负荷计算，由此对主变压器进行选取。在经济性与可靠性角度来选择主接线的方式。重点进行短路计算，电气设备包括66kV的电力设备及其10kV的电力设备选择及其校验，还计算与整定了继电保护，其中包括线路保护，变压器保护及其备用设备与备用电源的自动投入。 关键词：继电保护；电气设备选择；短路计算；主接线；变电所 Industrial Park 66kV substation design Abstract TAIAN County is located in central LIAONING Province, LIAOHE River Delta hinterland. Convenient transportation and has obvious advantages of the East Asian Economic Circle and BOHAI Economic Zone, is the breadbasket of LIAOHE Plain. Industrial park construction and implementation in 2001, to date, has become a full-featured development pilot area to expand economic development and growth areas.The design according to the power load data Anshan City, TAIAN County Industrial Park, the area has made the ground 66kV substation design. Design includes: selecting a load calculation and transformer selection, main terminal design, short circuit calculations and high-voltage electrical equipment, substation layout, protection and so on. The design is based on the actual load, to the best run substation basis, in accordance with the relevant regulations and standards, we completed the design of 66kV substation.Firstly, the design of the transformer substation load calculation, the main transformer selection. Determine the main wiring from the perspective of economy and reliability. Key short-circuit calculations, electrical equipment including equipment selection and verification 66kV and 10kV equipment, setting calculation of relay protection, including protection calculation transformers, circuit protection calculation, automatic backup power and backup equipment investment. Keywords: Electrical equipment selection；protection；short circuit calculations；substation；main terminal 目录
