Why power stations are located far away from the major load Centres?

Hydropower plants, have to be located on rivers at suitable places depending upon convenience. These and Thermal plants of large size supply power to faraway places as th they are designed to have large capacity after supplying local requirements.

Why do power stations need to be near water?

Nuclear plants are built on the shores of lakes, rivers, and oceans because these bodies provide the large quantities of cooling water needed to handle the waste heat discharge.

Where are most power plants built?

Top 20 largest power producing facilities

Rank	Station	Country
1.	Three Gorges Dam	China
2.	Itaipu Dam	Brazil Paraguay
3.	Xiluodu	China
4.	Belo Monte	Brazil

Which of the following power plant can be installed close to load center?

It is not continuous source of energy because its output fluctuates with change in flow rate of water with season. 6. Hydroelectric power plant is generally located near load centre.

Why are power stations often built directly next to coal mines?

Generating stations are sometimes built next to a mine; especially one mining coal, such as lignite, which is not valuable enough to transport long-distance; so may receive coal by conveyor belt or massive diesel-electric-drive trucks.

Why coal power stations are located in Mpumalanga?

It was in the Mpumalanga Province, rich in coal reserves and thus perfect for the construction of coal-fired power stations, where our power system finds its roots. Power stations were built and transmission and distribution infrastructure grew until they reached every corner of the province and then the country.

Why are nuclear power stations built near the sea?

To cut a long story short, power plants need cooling systems; seawater is abundant, cold, and – above all – free. Nuclear is the “thirstiest” power source, as it tends to be less efficient than coal or other sources of thermoelectric power.

Why do power stations need cooling towers?

As the name suggests, a cooling tower’s primary function is to lower temperatures – specifically of water, or ‘cooling water’ as it’s known at Drax. Power stations utilise a substantial amount of water in the generation of electricity.

How is electricity made in a power station?

Electricity is produced at a an electric power plant. Some fuel source, such as coal, oil, natural gas, or nuclear energy produces heat. The spinning turbine interacts with a system of magnets to produce electricity. The electricity is transmitted as moving electrons through a series of wires to homes and business.

Why is the load on a power station variable?

The consumers require their small or large block of power in accordance with the demands of their activities. Thus the load demand of one consumer at any time may be different from that of the other consumer. The result is that load on the power station varies from time to time.

Why are load curves drawn?

Load curve decides the installed capacity of a power station. It is helpful in choosing the most economical sizes of the various generating units. The load curve estimates the generating cost. It decides the operating schedules of the power station, i.e., the sequence in which the different generating units should run.

Why coal-fired power stations are built near coal mines?

For centuries, coal was the only fuel source available in large quantities. Power stations were built near coal mines so that coal did not have to be transported over long distances.

What happens if you live near a power substation?

Since skin is directly exposed to these radiations, it can be badly damaged. Studies have been done on people that live within 300 meters of a substation. There is some evidence to suggest an increased risk of some type of cancer.

What is a power station?

Power stations are complex arrangements of individual plant items, equipment and mechanical and electrical engineering systems.

Why is the power generated at a generating station at low voltage?

The power generated at a generating station is at a low voltage level, as low voltage power generation has some economic value. Low voltage power generation is more economical (i.e. lower cost) than high voltage power generation.

What is the difference between load center and transmission system?

Load center is the place which consumes maximum power. Hence there must be some means by which we can transmit the generated power to the load center. Electrical transmission system is the means of transmitting power from generating station to different load centers.
