Abstract

This paper presents a real power system which consists two types of power supplies. The power system consists a wind farm and a hydroelectric power system and other system components, such as loads, transformers, transmission lines and compensatory. First, a harmonic analysis is performed for a system in Greece. Then, a real system in Iran is simulated using the model of System’s harmonic components and the produced harmonies are studied. Network parameters also belong to information of Iran’s transmission and distribution lines. First, power generation sources individually enter the circuit, then the current and voltage harmonic distortion generated by the wind farm and hydro power plant is analyzed and compared to each other. A real network is analyzed her by two methods of frequency scan and fast Fourier transform (FFT). Different typologies are implemented and the results are analyzed by MATLAB/Simulink. Finally, voltage and current harmonic components are determined using FFT analysis and it is obtained that harmonic distortion generated by wind farms is significantly more than harmonic distortion of hydropower plants.
