Applications of AC Generator

Let us see some applications of AC generators in real-life.

• AC generators are used as a power source in major power stations like wind turbines, and hydropower plants where they convert mechanical energy of rotation into electrical energy. Therefore, AC generators forms an integral part in energy conversion and are used widely in power plants.
• After the generation of electricity, AC generators are also used in transmission lines for transmitting power over long distances. This power is supplied from power plants to various cities, industries, and other institutes. the ability of transformers to step up or step down is used for transferring the electricity over large distances with minimum loss.
• AC generators are used as a backup source in different industries that work on electricity. In case of power outrage, AC generators can be used temporarily for generating electricity. This is important for factories that are largely dependent on electricity for all the basic operations like manufacturing, designing etc.
• Since AC generators allow direct control over the generation of electricity, they are often used in research and development purposes where scientists require stable and controlled power for testing. Here, AC generator generates just the right amount of power which is necessary to drive the components and perform the analysis.
• In certain areas where the main source of power is unavailable, AC generators are used to provide power to operate the lighting, sound systems, stages, and other equipment in any event. This can be any entertainment event like parties, functions or inaugurations.

To more understand the Applications of AC Generators let’s go through some of the examples

Examples of AC Generators

Let us now understand the applications of AC generators through examples.

• Power Source: Power Plants like hydropower plants need power on a large scale and this power is generated using AC generators. Power plants like the one with wind turbines have large turbines that rotate when high-speed winds strike the blades. The wind turbine then is connected to the shaft of the generator. As the rotor is moved in the magnetic field, it induces an alternating current in the coil which is then transported to various industries for power usage. Other examples include plants based on steam, water, wind, and gas.
• Long Distance Transmission: The power generated needs to be transmitted from one point to another , AC generator thus becomes an ideal choice for long distance transmission. During the transmission of this power, certain power is wasted due to the resistance of the transmission line. To reduce this wastage of power , we need high voltage signals and this can be achieved only using AC generator which allows us to step-up or step-down the voltage. Using this, the voltage is stepped up while traveling through transmission line and is stepped down to bring it to domestic limit.
• Power backup source: You might have seen that the majority of residential houses are equipped with backup generators. These power generators are very useful in cases when the main power source is unavailable. For example in situations like floods, or lightning the main power source is unavailable and the backup source turns on automatically to supply power for essential devices like lights, refrigerators and the other source can be used when power returns.
• Transportation: AC generators are also used in transportation since they can be used to generate the power required to run electric vehicles. For example, electric trains require power to control the train’s motor. This power is generated through the overhead cables present above the train. This is a common usage of AC generators especially in urban areas to avoid traffic.
• Industrial and Residential Application: Different industrial and residential complexes require AC generators to power certain devices. In case of power outrage, all the nearby power stations are notified and AC power is transmitted over long distances through transmission lines. This ensures that even in case of power outrage, industries can continue their operations without any loss or interruption.
• Research and development: AC generators are used in the field of research and development (R&D) to control the power needed. AC generators are used to supply electrical power which is then used for testing purposes. Power is needed to supply electrical power for signal generators, spectrum analyzers, and oscilloscopes. The power requirement for these instruments is quite specific in terms of voltage and frequency and AC generators allow researchers to control this power.

AC generator is an important tool used in the electronics field to study different concepts therefore, it becomes necessary to study what is an AC generator. In this article, we will study the AC generator and learn how it is useful in our daily lives. We will try to study the applications of AC generators through some real-life examples. Later, we will study the advantages and disadvantages of using an AC generator. In the end, we will discuss some potential developments in AC generators and how can impact future trends.
