Abstract
This paper is the designation to 6*200MW----- thermal power plant electricity part.
The paper is divided into two major part the manual and calculation books, expatiation every kind of most basic request of equipments choose with principle basis and the process of calculation. Among them the first part divides nine chapters. choice for transformer, including: the definition of the main technique in number, capacity, model number¡etc. of main transformer, high voltage reserved transformer and high voltage factories in Power plant. electricity lord connecting line, primarily introducing the importance of electricity lord connecting linear, basic request of designing, basic request, the advantages and fault of every kind of connecting line form and choice of lords connect. the factory connects the line with the electricity, including: the total request of the electric boundary used by plant, bus designing in plant. a calculation on short current is the most important part.
There are detailed introduction on purpose requirement general provision calculation on parameter transformation of network etc. choice of high voltage electrical equipment, including the principle of choice and requirement of bus high voltage circuit breaker isolation switch current transformer voltage transformer current limited reactor. But a designed principle requirement and 220kV power distribution equipment are introduced in it. A programming for relay protection and Auto equipment include the principles Auto equipment general requirement and the protection of generator transformer bus etc. The protection from thunder in power plant and distribution station include choosing with the design of the surge arrester, lightning arrester. The second part is calculation book. Separately has a choice calculation on main transformer and plant transformer. A calculation on short circuit current, to get each short circuit current number. There will be a choice of the high voltage equipment and then a check. The thunder protection compute, according to the surface area of the transformation station to give or get the lightning rod needle high. In addition, for the sake of convenient reader to the comprehension of the contents with apply, in the appropriate position additional drawing paper were settled. (The lord connection of the line picture, plate picture, crossing section drawing and defending the thunder protection drawing etc.)
Key Words: Power system Bus High voltage circuit breaker
