Disgrifiad
Wind turbine harmonic current emissions are a well-known power quality problem. These emissions flow through wind park impedance, leading to grid voltage distortion. Parallel resonance may worsen the problem because it increases voltage distortion around the resonance frequency. Hence, it is interesting to analyze the parallel resonance phenomenon. The study explores this phenomenon in wind parks and provides analytical expressions to determine parallel resonances. In the data file ,Resonance frequencies (kpi) are characterised in terms of the number of rows (m) and columns (N) and WP electrical parameters (Lgrid, LtrafoHV/MV, Lcable, Ccable, Dcable, LtrafoMV/LV). The frequencies from Matlab/Simulink simulations and their relation with the ratio (XC/XL)1/2 are available in the tables. Moreover, the results of the analytical expressions to determine the resonance frequencies and the corresponding errors are also available in the tables. The simulation and the analytical results are plotted in graphs. The analytical expressions are obtained by fitting the simulation results.
