This design including factory, including power supply system design : Calculation of load and compensation of the inactive power; Transformer substation main voltage transformer platform count and capacity , sureness of pattern; Mainly wire the choice of the scheme in the transformer substation; Pass in and out the choice of the thread; Choice of shorting out and calculating and switchgear ; Two return circuit sureness and choice that relay protect of scheme exactly make; Defend the thunder and protect the design with the earth device ; The workshop distribution line connects up the sureness of the scheme; Circuit wire and distribution equipment and protecting the choice of the equipment; And the electric design that lighted, there is drawing of circuit diagram.
This design according to the design specification can be divided into three parts, the first part of the design of each workshop substation, including scheme comparison, choose variable pressure transformer sets and capacity of what I choose, substation reactive-power compensation power load statistics, which I transformer variable pressure choice; The second part is
