Harmonics Step Filter Control Model In Household Electricity

A passive harmonic filter is a type of filter designed to mitigate the adverse impacts of harmonics by effectively attenuating multiple harmonic frequencies or a broad frequency spectrum. The objective of implementing a double-tuned damped passive filter is to improve the overall performance of the system with respect to electric power quality. This paper is to develop a simulation model for a harmonic step filter control system that meets the requirements of household electricity. This system is designed to regulate various parameters such as current, voltage, frequency, power factor, active power, and reactive power of the electrical load. The ultimate goal is to enhance control and improve the quality of electricity consumption. household. The proposed research methodology involves the development of a 6-step control simulation model utilizing Matlab Simulink. Subsequently, a control design model will be implemented using the ESP 32 microcontroller, PZEM004t sensor, and PZCT-02CT sensor. Additionally, a relay module will be employed to activate the damped double-tuned filter. This relay module comprises 6 steps, each equipped with a filter designed to respond gradually based on the power quality value. The results show that the Total Harmonic Distortion Voltage (THDv) is at 7.07%, the Total Harmonic Distortion Current (THDi) is at 47.55%, and a power factor of 0.68. By implementing the proposed damped double-tuned filter, a reduction in harmonic values can be achieved. Specifically, the THDv can be reduced to 1.1%, the THDi can be reduced to 0.65%, and the power factor can be improved to 0.77.
