摘要
本文在综合分析国内和大庆油田35kV变电所现状的基础上,以大庆油田35kV喇南变电所工程设计为研究课题,从喇南地区电网现状出发,进行负荷预测和负荷平衡,用方案对比的方法确定电源接入方式,采用冗余方法设计电气主接线,采用分层分布设计综合自动化系统。详细论述了半户内设计变电所在电气主接线、电气平面布置、短路电流计算及设备选型、防雷接地、综合自动化等方面的设计特点。本设计以实际负荷为依据,以变电所的最佳运行为基础,按照有关规定和规范,完成了满足该区供电要求的35kV变电所设计。
为提高电网运行管理水平,设计过程中使用了多项新技术、新产品,用发展的视角优化设计,达到了无人值守水平。35 kV喇南变电所按批地面积,采用半户内式设计方式,在合理布置配电装置满足装置检修维护和消防要求的前提下,在大庆油田首次采用在35 kV变电所应用35kV户内敞开式组合电器和管型母线,从而达到了减少建筑面积和控制建筑高度,减少辅助设施占地面积。
Based on the comprehensive analysis of domestic and Daqing oil fields ,the thesis is on the basis of the status of 35kV substation to 35kV LaNan substation engineering design research project,from the current situation of the LaNan regional grid conducted load forecasting and load balancing,contrast from the program determined the power access, designed with redundant main electric connection,using hierarchical distributed integrated automation system design. Discusses in detail the design of semi-indoor substation in the main electrical wiring,electrical layout,short-circuit current calculation and equipment selection,mine ground,such as the design of integrated automation features. The design is based on the actual load to substation based on the best run in accordance with relevant regulations and norms,and completed to meet the power requirements of the area 35kV substation design.
To enhance the Electric power system management level,the design process uses a number of new technologies,new products,with the development of optimal design perspective,the level reached unattended. The transformer substation meets to criticize a ground to accumulate a request by using the semi-indoor design approach to meet the reasonable layout of power distribution equipment and fire equipment repair and maintenance requirements of the premise,first introduced in the Daqing oil field in the 35 kV substation 35kV indoor open Combined Electrical and tube-type bus,so as to achieve a reduction of floor space and control of building height,reduce the area of ancillary facilities.
