Topic: Describe the diagram about the hydroelectric dam.
Band 7 Answer
The process of producing electricity at a hydroelectric power plant is shown in the diagram. The procedure starts when water from a river enters a high-level reservoir and concludes when power is transmitted to the national grid. The process is generally divided into day and night phases, with the day phases incorporating energy generation from a river and water storage in a reservoir. The water returns in the other direction at night, heading towards the river and the first reservoir.
In the day stage of the procedure, river water is directed into a large reservoir that is supported by a dam. The power plant has an intake area that is open during the day and is closed at night. During the day, water rushes through the power plant's turbines to produce electricity. Power lines are then used to transmit the generated electricity to a national grid, and extra water is directed toward a low-water reservoir. The water in the low-level reservoir is returned to the power plant during the night stage. Over there, the turbines of the generator push it back into the high-level reservoir, which is shut down at that time. The higher level stores the river water, which later flows down to restart the cycle.
Band 7.5 Answer
The illustration demonstrates how a hydroelectric dam can be used to generate electricity. A reservoir of water serves as the process's starting point, and long-distance electricity cables serve as its finishing point. Water must first be gathered in a reservoir before it can be used to create electricity using hydropower.
A long tunnel known as a penstock is where the water enters after passing through an intake at the base of the dam to start the power generation process. On the other side, when no electricity is being generated, a sizable gate blocks the intake and stops water from flowing. To spin a turbine that is attached to a generator in a location known as the powerhouse, water must flow down the penstock when the intake is opened. The pressure this provides is then used to power the turbine. The water that has passed through the turbine also empties into the river below the dam at the same moment. The power lines that are used to transmit electricity across vast distances are connected to the generator in the powerhouse at the end. The electricity is subsequently distributed to users via long-distance transmission wires. Because of how water moves through nature, the process is regenerative.
Band 8 Answer
The technique used to generate electrical energy in a hydroelectric power plant is depicted in the figure. This is a two-step procedure, as this image shows when viewed in broad strokes. Two dams make up the plant: one is located higher up, while the other is closer to the ground.
The power plant generates electricity during the day, then in the evening, it pumps water back into the upper dam using some of that energy. The turbine is situated at the lower end of the power plant, and a sizable amount of water is continuously pumped there from the high-level reservoir. The liquid's force propels the turbine blades, which then turn the generator's generator. Electricity is generated as a result, and electrical lines are then used to transmit it to the national grid. Additionally, the used water is gathered in a dam that is located below ground level. The fluid is pumped back into the high-level reservoir throughout the night by the turbines, which are operating in the reverse direction. In order to help with this transfer, the generator functions as a motor. This cycle keeps going and continues to produce electricity. The electricity is then sent through long-distance transmission lines to end customers. The procedure is regenerative because of the way water flows in the natural world.
