Power quality refers to the characteristics of electrical power, including voltage, frequency, and waveform, that affect the operation of electrical devices.
Typical products for power quality improvement include:
Uninterruptible Power Supply (UPS): UPS systems provide backup power during outages and voltage sags, ensuring a continuous and stable power supply to critical loads.
Voltage Regulators: Voltage regulators automatically adjust and stabilize the output voltage to maintain consistent levels, compensating for voltage variations and enhancing power quality.
Active Power Filters (APF): APFs are used to mitigate harmonics and other power quality issues caused by non-linear loads. They inject currents that are phase-shifted and cancel out the harmonic components, improving the overall power quality.
Energy Storage Systems (ESS): Energy storage systems, such as batteries or flywheels, can store excess energy during low-demand periods and release it during peak demand or power quality disturbances. They help manage grid instability, voltage fluctuations, and frequency deviations.
Static Var Compensators (SVC) and Static Var Generators(SVG): SVC and SVG are used to regulate voltage and reactive power support. They can quickly inject or absorb reactive power to stabilize voltage levels and improve power quality.
These are just a few examples of products and systems that can help improve power quality by addressing voltage fluctuations, frequency variations, power factor issues, and other disturbances in the electrical grid.
