But the the power and the voltage of the power system designed and the
main line designed are very important.Because its retiability 、 Economy and
mobility are directly affecting the entire power network and plant dependability
、
Economy and elasticity. Still affecting the main design in the way of the
electricity 、 Short circuit calculation 、 The equipment selection check is up
to standard to be contain . This design eiectricat net programe after the economy
comparatively afterwards finally follows in the of choose selects taller one of
dependability and the lower ecomomy to act as the last scheme.
Besides, the Short circuit calculation affecting the Selection of capital
equipment and checkIt also is the very significant Section in this design .Whether
or not the right design are able to affect secure quality of entire electric power
system .This rule designed in line with dependability and security is completed.
