Bu araştırmada, türbin olarak kullanılan santrifüj pompanın jeneratör olarak
kullanılan asenkron makinesinin, şebekeden izole olarak çalışırken değişken yük
koşullarındaki performansının yükseltilmesi için elektronik kontrol kartı
tasarlanmıştır. Kendinden ikazlı çalışan üç fazlı asenkron makine ile tek fazlı
yüklerin beslenmesi incelenmiş balast yük sürücü kartı hazırlanmış ve test edilmiştir.
Yük kontrol kartının asenkron jeneratör uç gerilimini kontrol etmesi için PID kontrol
sistemi kullanmıştır.
PID kontrolü algoritmasında balast yükün oransal kontrolünü sağlayan PWM
modülasyonun başarılı şekilde çalıştığı ve jeneratör çıkış gerilimini istenilen gerilim
seviyesinde ve frekansında tutabildiği tespit edilmiştir. Kontrol ve sürücü kartının
oluşturduğu harmonik bozulmanın limitler dahilinde olduğu ve jeneratör sargılarında
fazladan bir ısınmaya yol açmadığı tespit edilmiştir.,In this research, the electronic load control unit has designed on offline asynchronous
generator at centrifugal pumps as turbines to improve electrical performance during
variable load conditions. Feeding of single phase loads by self-excited three-phase
asynchronous machines was examined and ballast load driver card was prepared and
tested. The PID control system is used to control load driver board for adjusting
generator terminal voltages.
In the PID control algorithm, it has been determined that it works very successfully
with PWM modulation which provides proportional control of ballast load and can
keep generator output voltage at desired voltage level and frequency. İt has been
found that the harmonic distortion caused by control and driver card is within the
limits and does not cause any additional heating in the generator windings.
