Abstract
This paperdesign a 110KV substation.Firstly,according to the gaved system,
electricity line and the parameters of load ,which provided by the assignment
book,through considering the substation which will be built and feeders,analysising
load materials,confirming the Main electrical wiring form of 110KV、35KV、10KV
side based on security,economy and reliability,then conform the numbers,volume and
type of the main transformer through load calulation and supply district,thus getting
the parameters of all the component,simplify electric circuit,select short point carry on
short circuit calculations operation circuit, select and check out electrical equipment,
including bus,breaker, disconnect switch, voltage transformer, current transformer and
so on,so that conform the distribution apparatus.Configurating relay protection and
setting-calculation for the electricity line,transformer and bus according to the load
and short calculations.At the same time,this paper analyse simply lightning protection
and grounding system.Finally,two pictures be drawed which include Main electrical
wiring diagram and 110KV Power distribution equipment sectional drawing interval.
