Abstract. This paper discusses the most prominent topologies of single phase synchronization methods. The four topologies studied in this review are Zero crossing detection, Fourier analysis based filter, Phase locked loops and Kalman Algorithm based filter. Experiment and/or simulation from cited literatures verify merits and drawbacks of all methods. By sheer volume, phase locked loop still emerges as the most popular and versatile. However, it can be concluded that other topologies are on par if not better in terms of performance. Zero crossing detector method shows exceptional performance in all areas. Digital filter based on Kalman filtering and Fourier analysis can track grid voltages very quickly.

“…The extracted sequence components are fed into an adaptive FIR filter block that is used to attenuate signal distortions such as harmonics and wideband noise. The filtered positive sequence signal, denoted as V + , is fed into a single phase synchronization system based on a DC compensated zero-crossing and peak detection (D-ZCPD) algorithm [17]. The purpose of the D-ZCPD is to generate magnitude (|V * + |), frequency (f EST ), and phase (θ + ) estimates of the positive sequence component.…”

This paper presents a Sequence Detector Synchronization System (SD-SS) capable of extracting the positive, negative and zero sequence components of a three phase signal. The system is frequency adaptive, and provides real time frequency, phase and amplitude estimations of the extracted positive sequence component. The SD-SS is able to operate over a wide range of frequencies (40-2000Hz), and in the presence of significant input signal distortion (THD as high as 100%). The SD-SS dynamically compensates for DC offsets and is capable of achieving parameter estimations in compliance with the IEEE Std.C37.118-2011 for synchrophasors. The system employs an adaptive FIR filtering technique that offers a high degree of immunity to harmonics and notch-types disturbances over the full operating range of frequencies. In the event of input transients such as balanced/unbalanced amplitude sags and swells, balanced/unbalanced phase steps and positive or negative frequency ramps (up to 700Hz/sec), the system achieves a worst case transient response time of 2 cycles of the input period. The SD-SS is implemented as a proof of concept on a Field Programmable Gate Array (FPGA) platform.Index Terms -synchrophasor, PMU, Std.C37.118-2011, positive sequence tracking, dynamic frequency range, fast transient recovery.

A three phase synchronization system suitable for control and monitoring of power systems applications is presented. The Positive Sequence Filter Synchronization System (PSF-SS) is frequency adaptive and provides real time frequency, amplitude and phase estimates of the extracted positive sequence component. The PSF-SS is capable of operating over a wide range of frequencies (40-800Hz), and in the presence of significant input signal distortion (THD≤100%). The PSF-SS is capable of achieving parameter estimations within 0.5% of the nominal value for worst case scenarios. The system employs adaptive filtering techniques that offer a high degree of immunity to harmonics, inter-harmonics and notch-types disturbances over the full range of operation. In the event of input transients such as balanced/unbalanced amplitude sags and swells, balanced/unbalanced phase steps and positive/negative frequency ramps (≤250Hz/sec), the system achieves a worst case transient response time of 2 cycles of the input period. The PSF-SS is implemented as a proof of concept on a field programmable gate array. The proposed system has the highest frequency ramp tracking capability of any positive sequence synchronization system developed to date.Index Terms -dynamic frequency range, fast transient recovery, grid monitoring and control, positive sequence tracking, synchronization system.
