Brushless exciters dominate the excitation systems due to the fact that they are low maintenance, very reliable, and efficient. No mechanical wear with no carbon brushes and no down time on the job. Base thermal and hydroelectric power plants with around the clock power supply love to utilize brushless excitors due to their long term characteristics and less arcing of electricity.
Brushless exciters have also seen extensive usage in high-power generating systems where constant and stable excitation is required to ensure grid stability. North American and European hydroelectric power plants, for instance, have been switching excitation equipment with brushless systems to enhance efficiency and reduce long-term maintenance costs.
In shipboard applications, too, where reliability to propulsion equipment is the ultimate concern, brushless exciters are the most suitable option owing to their resilience to harsh conditions.
Static exciters are more and more finding applications in excitation systems, particularly in the applications that require stringent voltage regulation and rapid response. The systems utilize power electronics for dynamic management of excitation current and thereby are suitably appropriate for use in applications wherein voltage oscillation must be inhibited, e.g., power generating plants and green energy networks.
Gas turbine power plants, particularly of the Asian and Middle Eastern markets, are increasingly leaning toward static exciters since they can supply voltage stability under a rapid change in load. Due to increased offshore wind farms, static excitors are applied to attempt and get best generator output under varying wind patterns. Increased development of alternative power sources finding its way into the grid is one of the major growth drivers in this segment.
Electronic controllers are the first preference of excitation systems in today's times due to their potential for integration with state-of-the-art automation and grid management strategies. They incorporate remote control pre-programmed together with real-time monitoring and constitute priceless assets for power plants with a view to achieving maximum efficiency without sacrificing system reliability.
In Europe, where development in smart grids is taking place, digital controllers are increasingly being utilized to attempt to provide the quality of power and seamless transition of renewable sources. Added to this, industrials such as chemical process industries and steel industries driven by heavy machinery are incorporating digital controllers as part of their efforts to regulate precise excitation control as well as mitigate voltage sag that could interrupt industrial production.
Increased utilization of Industrial Internet of Things (IIoT) in power systems further ensures market dominance by digital controllers.
In spite of the trend towards digitization, analogue controllers still exist in niche corners where cost is the overriding factor as well as simplicity is the overriding factor as well. Analogues find application at times within infinitesimally small industrial applications and places that have not yet experienced their infrastructure redeveloped.
Analogue controllers are used by Africa and other developing nations of South America on small- and medium-sized thermal and hydroelectric power plants in the excitation system. Analogue controllers are the major strengths because they are just designed; thus, little technical know-how is needed in order to repair and maintain them. Secondly, companies with legacy systems prefer using analogue controllers because they want to avoid digitized upgrades, which lead to complication.
Synchronous generators are the largest application segment of excitation systems due to widespread use in power generation and industrial backup systems. Synchronous generators need stable and reliable excitation to regulate voltage levels, and hence excitation systems are the priority of large power plants and grids.
China, India, and the USA are also putting major investments in expanding power generation capacity, which will also continue to require synchronous generator excitation systems. Moreover, the high growth of nuclear power plants in Eastern Europe and South Asia is prompting excitation system producers to perceive order surges for large-capacity synchronous generator products.
Synchronous motors are gaining prominence wherever constant speed and high power effectiveness are paramount. Synchronous motors need to be supplied with robust excitation systems to ensure smooth operation in duties like mining, cement, and pulp & paper.
Synchronous motors drive heavy-duty conveyors, crushers, and grinding mills in mining operations in Australia and Canada. Excitation systems in the industry are influenced by requirements of accurate motor control and efficiency. Cement factories globally are also putting money in efficient synchronous motors and sophisticated excitation systems to help lower energy bills and usage.
As the rate of industrial electrification increases, synchronous motor excitation system demand will also increase, especially in the efficiency- and sustainability-driven, power-intensive industries.
Excitation systems is a competitive market with long-standing global players and local producers driving growth through innovation. The key players have massive market shares and concentrate on advancements in digital control, automation, and high-performance power management solutions.
