Application of wind rose for wind turbine installation

TL;DR: In this article, the vertical wind shear is also represented in a wind rose for eight directions, and the power exponent law is also used for calculation power exponent of the wind turbine in Pune city.
Abstract: In a conventional wind rose only wind frequency, magnitude, and direction of wind for a particular site is given. But in this paper vertical wind shear is also represented in a wind rose for eight directions. In that diagram minimum vertical wind shear and maximum vertical wind shear for a particular site is represented. For calculation power exponent law is also used. Representation of vertical wind shear in a wind rose is the research component in this paper. The wind rose for vertical wind shear may be useful to predict the flicker initiated in the wind turbine. in this research readings are taken at different sites like Parwati hill, Jambhulwadi lake and Taljai hill in the Pune city. The wind rose of vertical wind shear for one of the sites is given.

TL;DR: In this article, the authors presented the study and application of the wind rose in issues of installation of distributed generation systems also known as in-situ generation specifically of vertical axis (VAWT) and horizontal (HAWT) wind turbines for different points of Lima.
Abstract: This paper presents the study and application of the wind rose in issues of installation of distributed generation systems also known as in-situ generation specifically of vertical axis (VAWT) and horizontal (HAWT) wind turbines for different points of Lima. To do this, we selected 4 different places in Lima, urban areas with a high population density and with the presence of buildings, and on the other hand rural areas with a smaller population and in some cases with a large wind resource due to the absence of buildings that prevent the wind flow. In that sense, we chose places that have sufficient information and are constantly measured by the corresponding institution, in this case the Senamhi, so the places chosen were Carabayllo and Campo de Marte for Metropolitan Lima on the other hand are Nana and Raimondi for Lima Provinces. This study also has the objective of analyzing the feasibility for the selection of one turbine over another by studying its annual and monthly wind rose and monthly average wind speed for the place where the wind turbine installation of the system is planned.

TL;DR: An environmental impact assessment due to the flow of effluents on the Sundarbans, one of nature's vast mangrove forests in the Khulna division of Bangladesh, using Gaussian plume model for statistical modeling.
Abstract: In this paper, we have carried out an environmental impact assessment due to the flow of effluents on the Sundarbans, one of nature's vast mangrove forests in the Khulna division of Bangladesh. As part of our investigations we have collected wind data from the meteorological department for the proposed plant location (Rampal), we have used this data to model the flow of effluents (mainly SO2 & NO x ) in the direction of the Sundarbans. We have plotted rose diagrams for each year using the raw data obtained from the meteorological department. We have considered three different scenarios for each year (i.e. maximum, minimum & average wind speeds) using Gaussian plume model for our statistical modeling. Graphs of concentration vs. distance have been plotted for each case to determine the maximum possible concentration of the effluent on the Sundarbans and the possible detrimental environmental effect has been evaluated using various international and national health and safety standards.

TL;DR: In this article, a simulation model of a MW-level variable speed wind turbine with a doubly fed induction generator was developed in the simulation tool of PSCAD/EMTDC.
Abstract: Grid connected wind turbines may produce flicker during continuous operation. This paper presents a simulation model of a MW-level variable speed wind turbine with a doubly fed induction generator developed in the simulation tool of PSCAD/EMTDC. Flicker emission of variable speed wind turbines with doubly fed induction generators is investigated during continuous operation, and the dependence of flicker emission on mean wind speed, wind turbulence intensity, short circuit capacity of grid and grid impedance angle are analyzed. A comparison is done with the fixed speed wind turbine, which leads to a conclusion that the factors mentioned above have different influences on flicker emission compared with that in the case of the fixed speed wind turbine. Flicker mitigation is realized by output reactive power control of the variable speed wind turbine with doubly fed induction generator. Simulation results show the wind turbine output reactive power control provides an effective means for flicker mitigation regardless of mean wind speed, turbulence intensity and short circuit capacity ratio.

TL;DR: Within these pages lies a comprehensive overview of both the traditional PQ indices in use today and new indices likely to be used in the future.
Abstract: DESCRIPTION Power Quality (PQ) indices are a powerful tool for quickly quantifying PQ disturbances. They also serve as the basis for illustrating the negative impact of electrical disturbances on components and for assessing compliance with the required standards and recommendations within a regulating framework. Within these pages lies a comprehensive overview of both the traditional PQ indices in use today and new indices likely to be used in the future.

TL;DR: In this article, a frequency domain method to study flicker propagation is presented, which is based on propagation of frequency components from WECS output currents throughout the grid, and an algorithm for flicker measurement in the frequency domain, which allows Pst calculation is proposed.
Abstract: Wind energy conversion systems (WECS) produce fluctuating output power, which may cause voltage fluctuations and flicker. Flicker assessment in networks may be difficult since its evaluation requires long computing time and special procedures to calculate the flicker severity index, Pst. In this paper, a frequency domain method to study flicker propagation is presented. This method is based on propagation of frequency components from WECS output currents throughout the grid. In this way, a fast flicker analysis in a network of any size can be performed. Also, an algorithm for flicker measurement in the frequency domain, which allows Pst calculation, is proposed. Several study cases have been performed, and results have been compared with time domain simulations, showing good agreement between them.
