From this visit, student got the detailed information and practical knowledge about Power Distribution and Transmission. Student got the knowledge about different devices used in substation like feeder, circuit breaker, transformer, isolator, bus bar, Protective relays, Lightening arresters, Wave Trap, Load break switches and their construction, working principle.
They got the idea how to read the single line diagram of power substation using different symbols used in diagram. Student cleared out practical knowledge of transformer as how it step down voltage 220 KV to 100 KV. They also got knowledge about new SCADA based system as you canhigh-voltage electric system facility. It is used to switch generators, equipment, and circuits or lines in and out of a system. It also is used to change AC voltages from one level to another, and/or change alternating current to direct current or direct current to alternating current. Some substations are small with little more than a transformer and associated switches. Others are very large with several transformers and dozens of switches and other equipment. There are three aspects to substationsreceives electric power from a nearby generating facility and uses a large power transformer to increase the voltage for transmission to distant locations. A transmission bus is used to distribute electric power to one or more transmission lines. There can also be a tap on the incoming power feed from the generation plant to provide electric power to operate equipment in the generation plant.
A substation can have circuit breakers that are used to switch generation and transmission circuits in and out of service as needed or for emergencies requiring shut-down of power to a circuit or redirection of power.
The specific voltages leaving a step-up transmission substation are determined by the customer needs of the utility supplying power and to the requirements of any connections to regional grids. Typical voltages are:
- High voltage (HV) ac: 69 kV, 115 kV, 138 kV, 161 kV, 230 kV
- Extra-high voltage (EHV) ac: 345 kV, 500 kV, 765 kV
- Ultra-high voltage (UHV) ac: 1100 kV, 1500 kV
- Direct-current high voltage (dc HV): ±250 kV, ±400 kV, ±500 kV
AIM of the Event:
The Electrical Engineering Department organized an industrial visit for the Second Year Electrical Engineering student to Maharashtra State Electricity Transmission Company 220/100/22 KV APTE Substation.
- Our main purpose for this visit is to be familiar with industrial environment and to get practical knowledge of electrical power transmission and distribution system.
