Power Quality Issues and Solutions

Introduction

Introduction:

Power quality refers to the consistent and reliable supply of electrical power that meets the specific requirements of sensitive electrical and electronic equipment. Any deviation or variation in voltage, frequency, harmonics, and other electrical parameters from the ideal sinusoidal waveform can result in power quality issues, which can cause equipment damage, malfunction, and downtime. In this blog, we will explore various power quality issues and their solutions.

Harmonics:

Harmonics are multiples of the fundamentalfrequency that are also present in the power system, typically due to non-linear loads such as electronic power supplies, variable frequency drives, and rectifiers. Harmonic distortion can cause voltage distortion, overheating of transformers, capacitors, and motors, as well as interference with communication systems and telephone lines. The solution for harmonics is to use harmonic filters, which are designed to filter out harmonics from the electrical waveform and provide clean power.

Voltage sags:

Voltage sags refer to temporary voltage drops, which can last for a few seconds or minutes, and happen due to various reasons such as motor starting, lightning strikes, and equipment faults. Voltage sags can result in equipment damage, malfunction, and downtime. The solution for voltage sags is to use uninterruptible power supplies (UPS), voltage regulators, and passive harmonic filters, which can provide stable voltage and minimal harmonic distortion.

Flicker:

Flicker refers to the variation in voltage that results in noticeable luminosity changes in lights and lamps. Flicker is caused by variations in load demand, such as electric arc furnaces and induction heaters, as well as welding machines and motor starting. Flicker can cause eye strain, headaches, and migraines, as well as image distortion in CRT displays. The solution for flicker is to use capacitors, thyristor-controlled brushless drives, and static VAR compensators (SVCs).

Power factor:

Power factor refers to the ratio of real power to apparent power in an electrical system. A low power factor, which is commonly caused by the presence of capacitive or inductive loads, can result in higher currents, which can increase circuit resistance, heating loss, and energy consumption. The solution for low power factor is to use capacitors and voltage regulators, which can improve the power factor by compensating for the reactive power.

Surge and spikes:

Surge and spikes refer to transient voltage spikes, which can be caused by lightning strikes, power switch-on/off, and system faults. Surge and spikes can result in equipment damage, malfunction, and data loss. The solution for surge and spikes is to use surge protectors and surge diverters, which can provide protection against overvoltage and enhance immunity against abrupt voltage changes.

In summary, power quality issues involve voltage sags, flicker, harmonics, low power factor, and surge and spikes. The solutions for these issues include harmonic filters, UPS, capacitors, voltage regulators, passive harmonic filters, thyristor-controlled brushless drives, SVCs, and surge protectors. By implementing these solutions, we can ensure consistent and reliable power supply, reduce equipment damage and malfunction, and enhance the overall efficiency and reliability of electric systems.
