Abstract

A wide-range synchronization system (WSS) for applications in utility and non-utility AC power systems is presented. The synchronization system provides information about the frequency, amplitude, and phase. The WSS is fully adaptive, extracts synchronization information from frequency and/or amplitude variant voltage/current signals and offers a high degree of immunity to wide-band noise, harmonics, inter-harmonics and impulse disturbances. A set of analytical expressions is developed to achieve high execution speed and low real estate utilization. The mathematical properties of the analytical expressions are presented. The WSS is implemented on a field programmable gate array (FPGA). The operating range of the implemented WSS is from a fraction of Hz to a few kHz and from 3% to 100% of nominal amplitude
