Özet
The increased use of power electronic based devices and the nonlinear
characteristics of circuit elements used in these devices have led to the
formation of harmonic components in power systems. The stable and safe
working of power systems depends on the foundation of quantities such as
voltage and current, which are sinusoidal and at 50 Hz frequency.
However, these foundation quantities lose their sinusoidal characteristics
because of many reasons and unwanted harmonic components occur in the
off-grid power system. It is highly preferred to use passive LCL filter to
reduce the harmonic components that occur in the solar system. The
proposed power system is a combination of solar panels, a DC/DC boost
converters, solar inverters, six-pulse rectifiers, passive LCL filters and RL inductive loads. A six-pulse uncontrolled rectifier produces 5th, 7th,
11th, 13th, 17th, 19th, etc. Harmonic components. A passive LCL filter is
used to reduce the input current of the total harmonic distortion (THDI) of
an uncontrolled rectifier. According to these results, the designed passive
LCL filters have a simple structure and control is not too complicated
provides significant advantages and are not complicated to control, which
provides significant advantages. Modelling of off-grid PV power system
and simulation was performed with Matlab/Simulink. Simulation results
showed that the THDI value reduced from 91.53 % to 2.927%. As a result,
LCL filter improves both the system efficiency and reliability of standalone PV power systems.
