Best harmonic analysis services in india
Many Indian power distribution companies have switched to kVAh billing in order to maintain strict requirements for reactive system drawdowns and to ensure proper Power Factor (PF) correction at the load level. Even after installing a capacitor bank at their end, consumers still experience Low Power Factors due to capacitor failure. One of the most common causes of capacitor failure is harmonics.
Harmonics have an impact not just on the electrical equipment in people’s houses, but also on the utilities. This research is an attempt by a power distribution utility to mitigate harmonics by the use of an Exception technique, leading to a win-win situation for all parties involved.
Annotation and Meaning of harmonic analysis :
A voltage or current that is a multiple of the system’s fundamental frequency is referred to as a harmonic in an electric power system. Harmonics are the shape or qualities of a voltage or current waveform in respect to its fundamental frequency.
Power quality concerns are frequently caused by harmonic frequencies in the electrical grid, which cause increased heating in equipment and conductors, variable speed drive misfiring, and motor torque pulsations.
Causes of Harmonics Distortions :
AC electrical loads are classed as linear or nonlinear depending on how they receive power from the mains power supply waveform. With a linear load, the connection between the voltage and current waveforms is sinusoidal, and the current is always proportional to the voltage; this is known as Ohm’s law.
Non-linear loads draw current in short, sharp bursts. Current waveforms are warped as a result of these pulses, resulting in harmonics that can create power problems for both distribution system equipment and the loads connected to it. Rectifiers, variable-speed drives, and electronic equipment that uses switched-mode power supply (SMPS) power conversion technologies, such as computers, printers, TVs, servers, and telecom systems, are examples.
Consequences of Harmonics Analysis :
When harmonic distortion enters a power system, it impairs its ability to operate at peak levels. Harmonics induce inefficiencies in equipment operations as the demand for electricity grows. The increase in overall current required results in higher installation and utility costs, overheating, and lower profitability.
Methods to reduce Harmonic distortion :
- Attempting to minimize the load’s harmonic currents. The use of a line reactor or transformer in series reduces harmonics while also providing transient protection.
- Adding filters to either suck harmonic currents out of the system, preventing them from entering in the first place, or to locally supply harmonic currents.
- Using filters, inductors, or capacitors to alter the system’s frequency response. Electronically delivering the harmonic component of the current into a non-linear load is how active filters work.
- Providing transformer connections in three-phase systems to decrease harmonic currents.
- For both utilities and industrial users, this is frequently one of the most cost-effective solutions.
Types of Harmonics in Electrical systems :
-
Current harmonics :
Relying on the load and how it interfaces with other network elements, current wave distortion can be difficult. The Fourier series transform allows any waveform to be deconstructed into a set of simple sinusoids that begin at the power system’s fundamental frequency and occur at integer multiples of the fundamental frequency, regardless of how intricate it grows. In power systems, harmonics are positive integer multiples of the fundamental frequency.
In a standard alternating current power system, the current varies sinusoidally at a fixed frequency, usually 50 or 60 hertz. A sinusoidal current with the same frequency as the voltage is drawn when a linear time-invariant electrical load is connected to the system (though usually not in phase with the voltage) .
2. Voltage Harmonics :
Current harmonics are the most prevalent cause of voltage harmonics. Because of the source impedance, current harmonics change the voltage provided by the voltage source. Current harmonics result in comparatively few voltage harmonics if the voltage source’s source impedance is low. Voltage harmonics are minor in comparison to current harmonics. As a result, it’s common to estimate it using the basic frequency of the voltage waveform.
Purpose of doing Harmonic analysis services :
When harmonic distortion enters a power system, it jeopardizes its ability to operate at peak levels. Increased power demand leads to inefficient equipment operation. Higher installation and utility expenses, as well as increased heating and decreased profitability, arise from increased overall current demand.
Harmonic distortion in the current and voltage of a power system can place undue strain on your installation and cause important system components to fail.
Harmonic analysis services are used to conduct in-depth analytical studies that are essential for compliance and better power system reliability. In these investigations, multiple Power Analyzers are employed to check distortion at various levels at the same timestamp.
