Active Harmonic Filters: Technology That Improves Power Quality and Efficiency
In today's electrical systems, power quality and efficiency are important factors. Harmonic distortions in electrical networks can reduce the performance of devices, damage equipment and cause energy loss. An important technology used to solve these problems is active harmonic filters.
What are Harmonics?
Harmonics are frequencies that are multiples of the fundamental frequency (such as 50 Hz or 60 Hz). In electrical systems, harmonics can cause unwanted fluctuations that can prevent the normal operation of devices or reduce power quality.
Role of Active Harmonic Filters
Active harmonic filters help control and reduce harmonics. These detect harmonic currents and reduce distortions in the electrical system by balancing or neutralizing these harmonics by generating reverse current. In this way, power quality increases, the life of the devices is extended and energy efficiency is achieved.
Active Harmonic Filter How Do They Work?
Active harmonic filters generally use semiconductor components and control systems. Sensors are used to measure the harmonics on the grid, and then inverters and control systems are activated to balance these harmonics by producing counter current.
What are the Advantages of the Active Harmonic Filter?
Harmonic Correction: Different from other passive filters. As such, active harmonic filters can deal with changing harmonics more effectively.
Flexibility and Control: Thanks to the control systems, the filters can be adjusted and optimized to adapt to different harmonic levels.
Low Losses: They can perform harmonic correction without large power losses as in traditional filters.
Active Harmonic Filter Application Areas
Active harmonic filters are used in many areas from industrial facilities to commercial buildings. Especially in environments where sensitive devices are located (e.g. hospitals, laboratories), power quality and continuity are critical. These filters support the healthy operation of systems by providing stable power in such environments.
Active harmonic filters are a critical tool to control harmonic distortions in electrical systems and improve power quality. plays a role. While this technology increases energy efficiency, it extends the life of devices and increases the reliability of power systems. It will allow it to be more robust and reliable.
