220kV Substation,Nawbasta,Kanpur

Substation An Electrical Substation is a subsidiary

station of an electricity Generation , Transmission And Distribution System where voltage is transformed high to low or reverse using transformer.

Examples of Substation:- 400kV/220kV substation 220kV/132kV substation 132kV/33kV substation 33kV/11kV substation 33kV/.4kV substation

220kV Substation It is devided into two(2) parts:-

A. Panel SectionA. Control Panel SectionB. Relay and Protection Panel Section

B. Switch YardA. 220kV SectionB. 132kV sectionC. 33kV section

C. Battery Room (Extra)

A. Panel SectionIt is a room which contains all types of

panels. It has two sections:-

Control Panel Section

It contain panels related to controlling of instruments. E.g.:- feeder panel, X-mer panel, etc.

Relay And Protection Panel Section

It contains panels related to relay systems and protection systems. E.g.:- Relay panel, line protection panel, etc.

B. Switch YardIt is the field where components used

in controlling supply and measuring supply(incoming and outgoing) are placed.

Some of these many components are:- C.Bs Isolators C.Ts P.Ts L.As X-mers, etc.

220kV Substation ,Kanpur

Incoming line220 kV from(i) Bhauti {PGCIL}

(ii)Fatehpur

Outgoing lines132kV to (i) Krishna Nagar

(ii)Malwah (iii)LML

33kV to (i) Harish Ganj (ii)Anandpuri,etc.

220kV SectionIt works on 220kV.There are two bus bars in which

one is main bus and the other is transfer bus of 220kV.

It has two 220kV incoming feeders i.e. From PGCIL ,Bhauti and Fatehpur.

The incoming 220kV line is from the Northern Grid.

132kV SectionIt works on132kV.It has two buses i.e. Transfer Bus

and Main Bus.220kV voltage is converted to

132kV voltage using a 160MVA transformer.

In other words it is 220kV /132kV substation.

This line is directly feded to many industries like LML , etc.

33kV SectionThis section works on 33kV.It has three feeders of 33 kV.One from 63 MVA transformer

and two from 40 MVA transformer.

132kV/33 kV conversion is done using 63MVA transformer and two 40MVA transformer.

In other words it is 132kV / 33kV substation.

Important TermsTripping – Power goes due to over load . It is

for the protection of components.Shut down – Power is cut due to

maintenance in progress. It is done manually.Break down – Power goes due to any fault in

the line. When fault is removed , power is back.

Rosting – Power is cut deliberately on order of higher authority due to shortage of power.

ConclusionOne must have never thought that

so many things are required for just switching on a television or a refrigerator or say an electric trimmer. The three wing of electrical system viz. Generation, transmission and distribution are connected to each other and that too very perfectly. Lots of labour, capital and infrastructure is involved in the system just to have a single phase,220V,50Hz power supply at our houses.

At last I would say...

Energy Saved Is Energy Produced...!
