Modeling, Limits and Baseline of Voltage Interharmonics Generation in Andean Wind Farms
The following study focuses on the analysis of voltage interharmonics based on power quality experimental data of Villonaco's Wind Farm. This park is located on the Villonaco hill, province of Loja at 2720 meters above sea level in the Andes of Ecuador. The study arises due to the problem that there are no standards to define the limits of interharmonics generation for power plants. This work consists of two aspects: the statistical modeling of voltage interharmonics and the generation of the baselines. The general proposed methodology, the application for Villonaco's wind farm and the results and conclusions obtained are detailed. In addition, taking advantage that the wind farm meets the power quality standards, the voltage interharmonics characterization is done, in order to provide the first interharmonics baseline in wind farms built on the Andean region.
Conditions are derived for the construction of total variation diminishing difference schemes with multi-point support. These conditions, which are proved for explicit, implicit, and semi-discrete schemes, correspond in a general sense to the introduction of upwind biasing.
