Hydroelectric power process

IELTS Task 1 : Hydro Electric

BC Hydro makes energy by using the effectiveness of going or falling water to make mechanical/electrical energy. BC Hydro yields over 43, 000 gigawatt hours of electrical energy annually to produce above 1.6 million residential, commercial and industrial customers. This energy is delivered using an interconnected system of over 73, 000 kilometres of transmission and circulation outlines.

Just how do we create this energy? The process starts before electricity also reaches consumers. The actions to creating electrical energy from a dam and just how its transported tend to be outlined below.

Hydro Electrical Generation program

1. Hydroelectric dam
Discover prospective energy stored in a water reservoir behind a dam. It really is changed into kinetic energy when the water starts moving along the penstock, through the dam. This kinetic energy sources are used to change a turbine.

2. Generator
The falling liquid strikes a series of blades attached around a shaft which converts kinetic power to technical power, and causes the turbine to rotate. The shaft is attached with a generator, so that whenever turbine transforms, the generator is driven. The generator converts the turbine's mechanical energy into electric energy.

3. Step-up transformer
Voltage could be the force which makes electricity movement. Generators usually create electricity with a minimal voltage. To ensure that the transmission lines to hold the electrical energy effortlessly over-long distances, the reduced generator voltage is risen to a greater transmission current by a step-up transformer.

4. Grid high voltage transmission lines
Grid transmission outlines, often supported by high metal towers, carry high voltage electrical energy over long distances.

5. Terminal Station
Terminal stations control power flow on grid transmission lines and lower the grid voltage to subtransmission current.

6. Subtransmission lines
Subtransmission lines provide power from terminal channels to large commercial customers or circulation substations.

7. Exactly how it is employed by the customer
Electric power are offered at transmission current to people of large amounts who have and function their own substations. Most clients, however, cannot take energy at transmission current, and need it be stepped straight down in a transformer.

8. Distribution substation
a distribution substation is something of transformers, meters, and control and safety devices. At a substation, transmission current is reduced to reduce voltages for circulation to residential, commercial, and small and medium manufacturing customers.
