A SEMINAR REPORT
ON INDUSTRIAL TRAINING
AT
“220KV GRID SUB-STATION, DAUSA”
SUBMITTED TO :- SUBMITTED BY:- MR. JITENDRA KUMAWAT RINKU KUMAR MEENAHEAD OF DEPARTMENT ELECTRICAL ENGG.ELECTRICAL ENGINEERING 10EDSEE099
Rajasthan State Electricity Board
RSEB was constituted with effect from 1 july 1957
In 19th july 2000 the rseb start the 3 sector in power system
1.Rajasthan Rajya Vidyut Utpadan Nigam ltd.(RRVUNL) in power genration
2.Rajasthan Rajya Vidyut Prasaran Nigam Ltd.(RRVPNL) in power transmision
3.In power distribution RSEB creat 3 companies Jaipur Vidyut Vitran Nigam Ltd.(JVVNL)Ajmer Vidyut Vitran Nigam Ltd.(AVVNL)Jodhpur Vidyut Vitran Nigam Ltd.(JdVVNL)
INTRODUCTION OF GSSA substation is an assemble of electrical component including bus-bar, power transformer, circuit breaker, isolator, lighting arrester etc. substation is use to distribute the electrical power after step down the voltage.
Design of a Sub-station
• Sub-station should be located at load
center
• Sufficient land area
• Grounding
• Easy of maintenance
• Possibility to Expand
• Reliability and Security
• Electrical design considerations
NEED OF GSSAfter the genration of electricity the electric power is not able to use as our purpose so we required the grid sub station.
YARD OF GSS:-
Yard of G.S.S. is the place there all equipments of G.S.S. take placed. They are connected to each other properly.
FEEDER
INCOMMING FEEDER:- 1. 220 kv From PGCIL BASSI 1
2. 220 kv From PGCIL BASSI 2
3. 220 kv From ANTA 1
4.220 KV From ANTA 2 (SAWAI MADHOPUR)
OUTGOING FEEDER:- 220 KV ALWER 33 KV BAPI
220 KV MANDAWAR 33 Kv CIVIL LINES 220 KV HINDAUN CITY 33 KV BHANDAREJ 33 KV PADSOLI 132 kv BANDIKUI 33 KV BAJORI
132 KV TOONGA 33 KV NANGAL RAJAWTAN 132 KV LALSOT

TRANSFORMER
Transformer is a static device which transformed electricity from one circuit to another circuit without change in frequency but voltage may be change
TYPE OF TRANSFORMER
1.POWER TRANSFORMER:-STEP-UP TRANSFORMER:
A transformer in which the output voltage is greater then the input voltage.
STEP-DOWN TRANSFORMER: A transformer in which the output voltage is less then the input voltage. It reduce the voltage and increase the current.
2.INSTRUMENTAL TRANSFORMER
CURRENT TRANSFORMER:- It is use to measure the current which step down by the power transformer
POTENTIAL TRANSFORMER:- It is use to measure the voltage which is step down by the power transformer. It also known as voltage X-mer . In India capacitive voltage transformer are used at 400 kv GSS.
INSULATOR
An insulator is a material whose stop the flow of electricity outside the conductor
TYPE:-1.PIN TYPE INSULATOR2. POST TYPE INSULATOR3.STRAIN TYPE INSULATOR4.SUSPENSION TYPE INSULATOR
LIGHTNING ARRESTER Lighting Arrester is a device which is use to discharge the over voltage to earth, which is coming from the sky.
CIRCUIT BREAKERCircuit breaker is a device which is use to break the circuit during the abnormal condition when the fault occure in the conductor .
ISOLATORIsolator is also used for the break the circuit when the line under no load condition for seafty , isolation and maintenance.
WAVE TRAPPERWave trapper is a device which use to trap the wave .
RELAYRelay is a equipment in G.S.S. which is use to detect and sense the fault.
P.L.C.C. :- Use of PLCC in mordren
electrical power system is mainly for telemetry and tele control system.
Tele means remote and telemetry refers to the science of measurment remote location.
CONTROL ROOMControl Room Is A Place In Gss Where All Equipment Are Controlled BAy The Help Of Automation Syste
CONCLUSIONGSS IS AN IMPORTANT PART OF POWER SYSTEM
ELECTRICAL ENGINEERS WORLDWIDE KEEPS LOOKING FOR WAYS TO IMPROVING NOT ONLY GENRATION OF ELECTRICITY BUT ALSO TRANSMITION AND DISTRIBUTION
PLEASE SAVE
ELECTRICITY
ANYQUERY ???
THANK YOU !!!!!!! For
GIVE YOUR IMPORTANT TIME !!!!!!
