Digital Frequency Multiplying Method for the Power System Frequency Tracking Based on FPGA

摘要：

The paper propose the digital frequency multiplying method based on frequency de-noising on FPGA, aiming at the frequency aliasing of the high frequency interference in the power system frequency tracking circuit. The basic principle and hardware realization are discussed.The performance of the system is tested using two different system clock, the experiments show that: This method can eliminate the error caused by frequency aliasing, and improve the interference immunity of the system. In addition, experiments also proved that using higher system clock can improve accuracy absolutely.
