An Implementation of Sustainable Solar Powered Mosquito Trap Device
(Daffodil International University, 23-01) Ahmad, Kanij; Arefin, Shamsul
Mosquito control is an ongoing problem that must be constantly monitored and achieved. This is due to the creature's ability to transmit a variety of deadly diseases, and mosquitoes kill one million people each vear. Traditional insecticide and bug zapper prevention methods are ineffective and have an adverse effect on the environment in a diverse range of ways, including the extinction of beneficial insects, mosquito biological evolution, and climate change. A solar-powered mosquito trap is developed in this study to attract mosquitos into the trap by sucking them toward a shock net while they are drawn to an SMD LED light.

Converter Based Frequency Adjustment and Protection of Grid-tied Wind Farm
(1st International Conference on Advances in Science, Engineering and Robotics Technology 2019, IEEE, 2019-12-19) Ahmad, Kanij; Mohammad, Nur; Quamruzzaman, Muhammad
Frequency adjustment and protection of a wind turbine due to wind gust is a salient aspect of the grid-tied wind farm. Both of them require conserving system stability. This paper presents an investigation of the converter based frequency adjusting method and wind turbine protection. A grid-tied wind power system model using the Doubly Fed Induction Generator in MATLAB is used. To regulate the active power output, synchronization between wind velocity and wind turbine speed is adjusted. Thus, wind farm operated at grid frequency and maximize turbine output. The control strategy of the converter based frequency synchronization of a grid-tied wind farm also includes protection subsystem. The protection system executed by receiving information from the logical block implemented in the wind farm model. It provides wind turbine protection by terminating wind turbine from a grid in abnormal wind conditions. The Simulation result validates the results and control methods.
Review on Frequency Adjustment for Power Systems with Grid Connected Wind Farm
(1st International Conference on Robotics, Electrical and Signal Processing Techniques, ICREST 2019, IEEE, 2019-02-21) Ahmad, Kanij; Mohammad, Nur; Quamruzzaman, Muhammad
Continues expanding of wind power harnessing demands an effective control system to improve quality power delivered from wind turbine to grid. A stable power system fully depends on the synchronization that means matching of frequency between the source of power generation and existing power grid. The prime objective of a wind farm controller is to ensure effective operation of the wind farm in any wind speed condition. Frequency deviation between the wind system and grid can challenge the well-built operation of a power system and can imbalance the synchronization between wind farm and grid. The strategy of frequency adjustment is developing time to time which starts from using droop controller based Induction generator to converter based Double-fed Induction generator. This paper summarizes an analytical study on various frequency adjustment mechanisms for a grid-connected wind farm.
