FPGA collaborated one cycle control method in VSC for standalone self-excited induction generator

Abstract

The building up of voltage in the three‐phase self‐excited induction generator (SEIG) is created by the residual magnetic-flux or excitation-capacitors. The frequency as well as voltage of the SEIG is reliant to the excitation-capacitors, prime mover speed, magnetization characteristics, and loads. Generally, the electrical loads are continuously changing, with respect to the prime mover speed. Commonly, in SEIG the speed control regulators are used regulate prime movers. On the other hand, this method is equally expensive besides, unable deal transient epochs. There are control methods have been literature for frequency and voltage control regulations of SEIG. The SRF and IRP methods are very attractive method to deal these cases of transient periods. However, these methods are influenced when the reactive power variation fails on one occasion stator is not pay compensation with load. Henceforward, an alternate method is recommended using a one-cycle control (OCC) for voltage-source converter (VSC) connected with DC link chopper (DC-Side), which keeps better frequency and voltage regulation of SEGI. Field programmable gate array (FPGA) digital implementation for power electronics claims has revealed an emergent interest of many electrical researchers. Intellectual property (IP) cores are the essential technology, since the power electronics controllers demands higher end pulse width modulation and controller design in power electronic applications assertions. In this paper the experimental investigation of OCC supports SEIG to cope up requirement to connected standalone load. The system is an analyzed for different frequency control study. In this study, the complete OCC and outside system loops are employed in Xilinx system generator collaborated Spartan FPGA-3A board.
