The growing popularity of solar and wind power is expected to drive the expansion of the excitation system market. Solar and wind power are renewable energy sources that generate electricity by harnessing the energy of sunlight and wind, respectively. As awareness of climate change and the environmental effects of fossil fuel consumption rises, there has been a significant shift towards cleaner energy sources like solar and wind power, which produce minimal greenhouse gas emissions and reduce air pollution. Synchronous generators are commonly used in solar and wind power plants to convert mechanical energy from wind turbines or steam turbines (in concentrated solar power plants) into electrical energy. For example, in January 2024, the U.S. Energy Information Administration (EIA) projected a 75% increase in U.S. solar power generation, rising from 163 billion kilowatt-hours (kWh) in 2023 to 286 billion kWh in 2025. Wind power generation is also expected to grow by 11%, from 430 billion kWh in 2023 to 476 billion kWh in 2025. As a result, the increasing adoption of solar and wind energy is propelling the growth of the excitation system market.

An excitation system is a control system designed to supply the required field current to the rotor winding of a synchronous generator. This process generates the necessary magnetic field for the production of electrical power. The excitation system plays a crucial role in regulating the output voltage and reactive power of the generator, ensuring reliable operation, stability, and a rapid response to transients during power generation. It is a fundamental component in power plants, contributing to the efficient and precise control of electrical output.

The primary types of excitation systems are rotational, static, and brushless. Rotational excitation systems rely on rotating components, such as a generator or motor, to generate the necessary magnetic field for power generation. This type is commonly employed in traditional synchronous generators to regulate voltage output. The controller type for excitation systems is categorized into analog and digital, and these systems find applications in various equipment such as synchronous generators and synchronous motors. End-users of excitation systems include the power generation industry, heavy industries, original equipment manufacturers (OEMs), and other sectors where precise control of voltage output is crucial.
