The Design Of 35 Kv Substation Based On Cais And Tube-type Bus

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.
