Harmonic Analysis of Irish Power System

Power is a crucial component of daily existence in the modern world. Most objects we use every day are powered in some way. We must employ the most cutting-edge power technology on the market to deliver electricity to people in a safe and fair manner. Harmonics raise the circuit’s current flow’s RMS value, which raises the loss. The electrical systems have been plagued by a number of issues as a result. Harmonics have an impact on the loads as well as the entire distribution system. Additionally, delicate office and production machinery and equipment might be harmed by harmonics. Harmonic faults might not always be immediately noticeable, and it could be challenging to tell them apart from everyday wear and tear.

Harmonic Distortion Explanation:

Harmonic problems may reduce the reliability of the power supply due to its tiny size. Electric current and voltage harmonics cause problems in power systems. Equipment may malfunction or fail when the power source contains numerous harmonics. Harmonics, or changes in the current waveform’s shape, are frequently introduced into an electrical system by a nonlinear load. Nonlinear loads and harmonics are produced in power systems by devices such personal computers, driven motors, fax machines, laser printers, switch-mode power supplies (SMPS), batteries, and uninterruptible power supplies.

What Justifies the Need for Harmonic Analysis?

Electrical systems become less reliable and efficient as a result of harmonics. Your power system’s dependability will rise if you apply harmonic analysis to identify harmonics there. Non-linear currents are created when power electronics equipment usage grows. The demands of the system led to the generation of harmonics. Equipment must adhere to energy efficiency standards and consume less electricity.

When Did Harmonic Analysis Become Significant?

The harmonic limits need to be examined if the total load or bus system readings are greater than 25% of the total load.
To fix harmonic-related problems, such equipment failure or damage.
When and how many non-linear loads will the plant be expanded?
When an additional capacitor bank is introduced to the electrical systems, harmonic analysis is required.

A sinusoidal waveform encounters a nonlinear load, causing distortion and harmonic generation in the system. Finding the existence or absence of harmonics in a system frequently requires harmonic analysis.

Benefits of Cutting Harmonics Out of the Power System

By minimizing the amount of energy wasted through cables, switch gears, and safety systems, harmonic analysis lowers operational expenses. It also aids in lowering power system losses.
It helps to eliminate excessive transformers and lowers the RMS current in the power system, which reduces the demand for cable, switchgear, and busbars.
Performance naturally increases when losses are reduced, and the RMS current value is lowered. Harmonics cause overheating of cables, transformers, motors, and capacitors in addition to increasing losses and raising the RMS value of current. The undesirable outcomes may force you to terminate a surgery or cause you to lose money.

Procedure for Conducting a Power Quality Analysis:

Make a single-line graph to display non-linear loads.
Watch out for the PCC (Point of Common Coupling), also known as the point of common connection.
The buses inside the building that could be impacted by harmonics should be brought to light.
Gather as much data as you can on nonlinear loads and the electricity provider’s historical harmonics performance.
Using the electrical system’s performance data and the ETAP (Electrical Transient Analysis Program) software, create a model.
Examine the harmonics, voltage, and current distortion levels. Choose a cure if the harmonic distortion is too great.
After implementing the mitigation strategy, do another harmonic analysis to confirm CEC compliance.
