POWER CONVERTER DESIGN AND ATS AUTO GENERATOR CONTROL (AUTOMATIC TRANSFER SWITCH ) • Phạm Hữu Thanh TEACHER: TS.Nguyễn Trí Cường CONTENT INTRODUCE ALGORITHM DESIGN RESULT CONCLUSIONS AND FUTUREWORK I INTRODUCE During operation, some common problems may occur such as: power failure, phase loss, voltage drop, overvoltage, phase difference, phase imbalance, noise on the line, I INTRODUCE When there is a power outage on the grid, special loads will require an alternate backup power source What is an ATS system? An automatic power transfer device, also known as ATS (Automatic Transfer Switch) is used to automatically transfer the load from the main power source to the backup source when the main source fails and vice versa when the main power is restored or switched intentionally II INTRODUCE ATS structure with main grid – backup generators This construction allows two generators to work alternately or in parallel, resulting in higher power generation efficiency and longer traction motor life II INTRODUCE The following requirements must be followed during operation: : Only startup one to three times each power outage After the engine has successfully operated for to seconds, the starter must be turned off Before putting oil into the combustion chamber of an engine, it must be dried It is vital to avoid repeated beginning when the mains voltage fluctuates or the grid voltage flickers When stopping, you'll need some time to cool off Diesel generator III ALGORITHM DESIGN Auto mode Manual mode III ALGORITHM DESIGN IV RESULT Time diagram in case of power on after hours 10 Time diagram in case of power on after hours Time diagram in case the generators not power up IV RESULT 11 V CONCLUSION AND FUTUREWORK CONCLUSION  The results of the performed test ensure the ATS-design’s functioning and compliance with requirements and constraints  Our design is appropriate for the subject of Project II and at a cheaper cost FUTURE WORK  In future work, we will broaden our approach by incorporating additional features such as display and monitoring on the webserver or the HMI 12 THANK YOU !
