Today, the importance of power quality for industrial and commercial consumers has grown exponentially, especially since today’s production and control processes rely on computer equipment that is very sensitive to power quality fluctuations and disturbances.

The electric current must have a pure sinusoidal waveform and must be maintained in voltage and frequency fluctuations. Why good quality? Power quality is often defined as the ability of a power grid to provide a clean and stable power supply as a continuous and always available source of power. There is no ideal source of energy in real life. In today’s power grids, deviation from these ideal conditions is constantly occurring due to increased nonlinear loads and other disturbing network loads. With the arrival of new manufacturers and technologies, which previously served as a stable operating environment, electricity generation has become more complex. All of this adds new challenges to electricity grid operators. The consequences of poor energy quality can cause serious damage to trade and the economy. At worst, poor electricity quality can be a threat to human life in highly sensitive environments such as hospitals. Good energy quality saves money and energy. The direct benefit of improving energy quality for consumers will be the reduction of energy costs and tariffs, the indirect benefit of which will be the prevention of damage and premature depreciation of equipment, as well as the prevention of production or data loss and employment. The quality of electricity can affect the overall performance of a company, and this is a fact that is unfortunately easily overlooked by managers. One of the most important challenges facing industries is the issue of power quality. If quality issues are not taken seriously, irreparable damage can be inflicted on the industry. With the advancement of electronic power equipment and their increasing expansion and the key role of this equipment in production processes, will increase the harmonic distortion in the power grid. Harmonics, on the other hand, are one of the most important concerns for the quality of power in the industry. Voltage distortion and resonance are very serious issues in the power grid or industry. Therefore, developing industries, more than others, need to examine the issues of power quality. In general, the study of power quality parameters in our country is rarely done. Therefore, in the first step, after visiting the power grid or industrial equipment, field installation and measurement and analysis of power quality parameters are performed for more accurate evaluation, after evaluating and discovering power network problems in terms of power quality parameters, simulations. The exact specifications of the electrical software will be presented in the report. To ensure the accuracy of the results, the results of field measurements are compared with the results of simulation according to the standards of Iran’s electricity industry, so the problems are examined in detail and practical solutions to improve power quality parameters are provided. .
