Overview of Hydroelectric Power Plants

Hydroelectric power plants are functional due to the use of the hydroelectric power plant components. The prime objective is to produce electricity. However, there are three types available such as; impoundment, pumped storage, and diversion.

An Impoundment power plant’s primary function is to reserve water and produce electricity. On the other hand, diversion power plants divide the river and supply the water to small canals without water reserves.

However, pumped storage power plants store energy. It uses the pumping water uphill method to reserve energy.

Importance of Understanding Plant Components

An operator needs to identify the purpose of every component of the hydroelectric power plant. Only then, he/she do the following tasks effortlessly; 

1. Take Right Safety Protocols: Understanding each part reduces the risk of accidents.
2. Run Efficient Tasks: Awareness of the components of the plants helps employees to run every operation smoothly. Also, it is easier to avoid damage and prevent breakdowns. 
3. Save the Budget: Adequate knowledge of every piece of equipment of the power plant helps technicians make the right decisions during repairs or replacement. 
4. Go with Maintenance Planning: Getting the complete details of every component helps to conduct the maintenance whenever necessary.
5. Go with Better Productivity: When understand everything, the operations become much smoother and more efficient. It leads to better productivity.

Key Components of a Hydroelectric Power Plant

Various components are associated with a hydroelectric power plant, such as;

1. Dam: It is one of the most vital parts of the entire process. It is the source that produces electricity efficiently by reserving water. It creates a water reservoir at a certain height. When the gate is released, the water comes with a great force. It dives upon the turbines and generates electricity. This ensures a constant supply of power.
2. Reservoir: It is like a container of river water. It stores water and releases it when the dam is required to produce electricity. The size and depth are the two important parameters of a water reservoir. The more water it stores, the dam can utilize it during the dry period.
3. Penstock: In the Hydropower innovations, penstocks are the most important part. It is a tool that uses an efficient way to transfer water from the reservoir to the turbine. The design of the penstock is to control the force of the water. It protects the turbine from damage. Also, it directs the water flow with precision. 
4. Turbine: It is the heart of the hydropower industry. A hydro turbine is the source that produces electricity. However, a strong mechanism is working behind to produce electricity. The power generation of a hydro turbine depends on water flow over its blades. The more spinning happens, the more electricity will be produced. Also, various types of turbines are there that have different levels of Energy efficiency.
5. Generator: A generator is a component in a dam that transforms mechanical energy into electrical energy. It utilizes the spinning rate of the turbine to collect the energy first. Then, the magnetic field present inside the generator produces an electrical current with the help of the generator’s coils. With a power line, it transfers the electricity to the grid, then to your home. 
6. Control Systems: If the dam is a body, the control system is the nervous system of it. This is the place where an operator will adjust everything like the rate of water flow, gate opening and closure, turbine speed, and other parameters. The operator works inside the control room to make sure that the dam is running efficiently. 
7. Transformer: It is the asset used for regulating the voltage in a hydroelectric plant. After the turbine produces the electricity, it may come out at a lower voltage. These transformers convert them into higher voltage. They are more suitable for domestic and industrial uses after the conversion of energy. 
8. Powerhouse: The centre of the renewable energy for a dam is called powerhouse. This is the place where all the components like turbines and generators are installed. Like all the explained processes of turbines, transformers, generators, and all, different reactions happen continuously at the powerhouse of the dam. In short, the powerhouse is the stronghold for protecting various equipment.
9. Intake and Outflow Systems: The purpose of the Intake System is to manage the water flow from the reserve to the turbine. The outflow system is the source that collects the energy released after electricity generation. Both systems are important for producing sustainable energy from hydroelectric power plants.

Importance of Regular Maintenance for Plant Components

Every mechanical equipment requires maintenance despite its size and usage duration.

The following maintenance protocols are common for a hydropower plant:

1. Annual Maintenance Contracts (AMC)

Annual Maintenance Contracts (AMC) deliver a competition to perform various maintenance-related activities. Each activity under the AMC follows routine inspections. If experts find any trouble, they will repair or replace the equipment for better and smoother operations of the hydropower dam.

1. Ensuring Efficiency and Longevity

Performing regular maintenance assures the long life of every machine. It also aids in the efficient production of electricity. The smooth processes use less energy and produce better results in the long term.

1. Common Maintenance Challenges and Solutions

With proper maintenance, the technicians and operators can avoid the following challenges:

• Wear and tear, 
• Corrosion, and 
• Unexpected breakdowns. 

When they avoid such trouble, they protect the dam from breaking down. Also, they prevent costly repair or replacement procedures.
