China is one of the few countries determined by the characteristics of resources to the worlds coal-based. Thermal power plant design is an important topic of grangduation design for electric power mager students. Because of its comprehensive content, covering wide range of knowledge, taking into account its complexity, we design only from the principle during this diploma project. This paper describes the design process of power plant, make the reader through the paper explaining the design of power plants have a general understanding. Articles in general can be divided into two sections: one moving part thermal power plant design; first part of the design of electric power plant. ? Thermal Power Plant in part of the design include the following main aspects: thermal system Jisuan principle, the boiler and its auxiliary equipment of choice, in principle thermal system mapping, pulverizing system map and comprehensive plans thermodynamic system drawing. This must be skilled in the use of AutoCAD.  ?In the electrical part of the design include: an overall analysis of power plants, electrical wiring and the main HV power design, short circu
