Abstract

Harmonic problem is one of the main problems that restrict the development of grid connected photovoltaic (PV) power plant. In this paper, a passive network model of harmonic transmission is established with detailed consideration of the electricity collection system structure of PV power station based on the topological structure of typical large-scale grid connected PV power station. The harmonic power flow calculation is carried out by using the nodal admittance method in MATLAB. The magnification of the harmonic voltage of each node with respect to the fundamental wave voltage is concluded. The point of common coupling (PCC) is selected as the analysis object, and compared with the calculation results of the neglect of the electricity collection system, it is found that the characteristic of the harmonic voltage amplification is obviously changed. In the end, the influences of the LCL filter on the harmonic voltage amplification of the transmission network are analyzed.
