Vector borne diseases are a threat to human health. Little attention has been paid to the prevention of these diseases. We attempted to identify the significant wetland characteristics associated with the spread of chikungunya, dengue fever and malaria in Kerala, a tropical region of South West India using multivariate analyses (hierarchical cluster analysis, factor analysis and multiple regression)...
In this paper, an adaptive linear element (Adaline) based voltage and frequency (VF) controller is proposed for an isolated wind energy conversion system employing a permanent magnet synchronous generator (PMSG) for three-phase four-wire loads. A three-leg Voltage Source Converter (VSC) with a Scott-connected transformer is used as the VF controller. The Adaline based neural network is used to control...
In this paper, a solid state voltage and frequency (VF) controller is proposed for a standalone wind energy conversion system (WECS) employing a permanent magnet synchronous generator (PMSG). The proposed VF controller consists of IGBTs (insulated gate bipolar transistors) based three-leg voltage source converter (VSC) with a battery energy storage system (BESS) at its dc link. The Adaline (adaptive...
In this paper, a battery energy storage system (BESS) based voltage and frequency (VF) controller based on isolated three-leg VSC with a zig-zag transformer is proposed for stand alone power generation using a permanent magnet synchronous generator (PMSG). An isolated distributed generation (DG) system is realised using fixed pitch wind turbine. The proposed stand alone wind energy conversion system...
In this paper, an autonomous wind energy conversion system (WECS) is proposed using a permanent magnet synchronous generator (PMSG). The voltage and frequency (VF) of the stand alone WECS is controlled using a voltage source converter (VSC) with a battery energy storage system (BESS) at its dc link. A Scott-connected transformer is proposed for the neutral current compensation of the three-phase four-wire...
In this paper, a distributed generation based on stand alone wind energy conversion system (WECS) using a permanent magnet synchronous generator (PMSG) is proposed with a solid state voltage and frequency (VF) controller. A high efficiency WECS is realised using a PMSG driven by a wind turbine with a gear system. The controller consists of IGBTs (insulated gate bipolar transistors) based voltage source...
