This paper presents an implementation of space vector-based hysteresis current controller (SVBHCC) for full converter wind generation (FCWG) system. SVBHCC is utilized to regulate current in the grid side converter of FCWG system to improve the performance of the generation system such as its ability to ride through grid faults during grid disturbances. Simulation studies are carried out using MATLAB/SIMULINK for a 5 x 2 MW FCWG system to validate the proposed control method. The results show that aforementioned current controller exhibits excellent transient performance using a simple control structure. In addition, the wind farm can help to ride through the grid faults without requiring additional control strategies.Index Terms--Hysteresis current control, full converter, wind farms, faults, and reactive power control.
The number of positive cases of COVID-19 has continued to increase since it was announced by the Government in early March 2020. According to the World Health Organization (WHO), the provision of hygiene and sanitation facilities is one of the most important means of mitigating the outbreak of COVID-19 and other infectious diseases. This study aims to evaluate the socialization of assistance in making automatic handwashing devices online to communities in Southeast Sulawesi as an effort to mitigate COVID-19. The socialization was carried out by collaborating with the Southeast Sulawesi COVID-19 SATGAS Secretariat as a display location for a prototype automatic hand washing device. Meanwhile, assistance is carried out through the implementation of webinars via Zoom and the publication of video tutorials on social media in the form of YouTube and other media. The performance evaluation of the mentoring program is carried out in two forms, namely searches on online media and through online feedback presented after the webinar. Based on the response from online media and the feedback, the public responded positively to this and some of them were interested in making similar hand washing devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
