The statement about the 220kv transformer area substation design, discussed some electrical transformer stations design (one part) in power systems engineering of the entire process. Through the main transformer stations wiring design, stations wiring design stations, short circuit current calculations, check electrical equipment moving and thermal stability, set the main electrical equipment models and the parameters, the operating mode, design over-voltage protection and mine devices , design general electric graphic and distribution devices flood, and without power compensation. Lastly,completed substation design in power system.
Limited to the specific design requirements and design time of constraints, The design only is a part of the electrical transformer stations, and its second part did not involve, which research it in future study and work.
KEY WORDS: Substation, Short circuit currents , Moving stability,Thermal stability,Over-voltage protection devices,Without power compensation
