Electricity and every citizens daily lives, if an extended power outage, peoples lives will bring a lot of inconvenience to the enterprise has brought huge economic losses. For coal mine substation is especially true if the sudden interruption of the power supply, it could have devastating consequences. The main function of the substation is a power plant produced electric energy conversion, monitoring, allocation process, to better use for the user load, to improve the reliability of power supply and power system stability. In 2014, there were Liaoning Power Grid monitoring alarms 6,946,139, of which the accident category 93149, the exception class , more limited class, displacement class 822 173 by the end of 2014, 500 kV substation stations are 22 daily 220 kV substation and the following day were 12 stations. Thus, the substation is an important part of the power supply, plays a very important role in the safe and stable operation of the entire power system. 35kV is commonly used in China a voltage level, this paper has important practical implications for the design of 35kV substation. This paper conducted a model under the given conditions 35KV substation preliminary design, select a main transformer substation, according to a procedure designed to determine
