摘要：The present paper analyses the possibility of using reference wind measurements in the estimation of energy production from wind farms on less complex terrains. For the purposes of the analysis the chosen site is located about 20km from the closest point of the reference measurements. A correlation was made between the proposed data from the reference measurements and the wind parameters were extrapolated to the wind farm site. The results of the study were compared with experimental ones, while giving recommendations for refinement of the results when using reference data.
其他摘要：The paper presents the experimental installation, the methodology and measuring apparatus used for experimental research of qualitative indexes of impurities separation out of grain seeds for combined separating systems (according to specific weight and aerodynamic properties of seeds). The experimental installation used was composed of a gravity separator with mechanical shaker with unbalanced masses (mounted on the platform working surface) and an aspiration installation with fan. The experimental research has aimed at quantitative and qualitative influence on separation quality index of the following operating parameters: material flow rate of shaking separator, the air flow of aspiration installation, tilting work surface, work surface oscillation amplitude. Based on data obtained by measurements and qualitative indicators the separating process indexes have been determined, namely: degree of impurities separation, degree of good seeds loss, as well as, the index of technological separation effect for different types of combinations of separation installation parameters.
