This paper compares the performance of harmonic filters to reduce harmonic distortion in an industrial power system. The comparison is done for single-tuned, double-tuned, high-pass, and C-type harmonic filters. As a result, the double-tuned harmonic filter performs better than the other types of filters by reducing Total Harmonic Distortion for the voltage and current waveforms. 

As the demand for renewable energy continues to rise globally, photovoltaic (PV) projects have become an essential component of the energy mix. Solar energy, while offering significant environmental benefits, introduces several challenges related to power quality when integrated into the grid. In this blog, we will explore the common power quality issues encountered in PV projects and provide solutions to mitigate their effects, ensuring stable and efficient grid operation.

In the intricate landscape of electrical systems, understanding and optimizing power factor correction (PFC) is of paramount importance. Power factor correction might not directly slash the overall electricity consumption of a device or system, yet it wields a significant influence in enhancing electrical efficiency, thereby potentially reducing energy usage indirectly.

Devices like STATCOM, APF, and SVG are designed to improve power quality by addressing different aspects of electrical systems. While they all use power electronics to enhance grid performance, each device is tailored for specific applications and offers unique benefits depending on system requirements.

IEEE Standard for Harmonic Control in Electric Power Systems (IEEE Std 519-2022), is a highly recognized and referenced standard, and has been updated in 2022 from its prior 2014 version. The purpose of the standard is to establish goals for the design of electrical systems that include both linear and nonlinear loads.

Active vs Passive Harmonic Filters: Understanding the Key Differences and Applications

In today’s increasingly complex power systems, the need for effective harmonic filtering solutions has never been greater. Harmonics—unwanted frequencies in the power supply caused by non-linear loads—can lead to issues such as equipment overheating, inefficiencies, and even complete system failure. To mitigate these harmful effects, engineers turn to harmonic filters. These filters come in two primary types: active harmonic filters (AHFs) and passive harmonic filters (PHFs). In this article, we will explore the differences between active and passive harmonic filters, their respective benefits, and how each can be applied to optimize the power quality of your system.

Harmonic distortion in power systems can affect energy quality and system reliability. Intone Power offers advanced Active Harmonic Filters (AHFs) that provide real-time compensation and flexibility, ensuring superior harmonic mitigation, voltage stabilization, and power factor correction for dynamic and complex power environments.

As modern electrical systems grow increasingly complex, the presence of harmonics in power networks has become a critical concern. Harmonics are unwanted electrical frequencies that distort the standard sinusoidal waveform, leading to inefficiencies, equipment damage, and increased operational costs. Understanding the importance of detecting and eliminating harmonics is crucial for maintaining power quality and ensuring the longevity of electrical systems.

The rapid expansion of renewable energy sources (RES) has significantly shifted the traditional model of large, centralized power plants and distributed electrical loads.

Today, many renewable energy installations are situated closer to industrial, commercial, or residential zones—a concept referred to as “distributed generation.” This trend is expected to grow substantially in the coming years.

Rooftop solar photovoltaic (PV) systems offer a sustainable energy solution but can cause power quality issues when integrated with low-voltage (LV) distribution networks. These challenges, such as voltage fluctuations, harmonic distortions, unbalanced voltage, and DC injection, disrupt both solar systems and the electrical grid, leading to inefficiencies and potential damage.
