Abstract:
The advent of GPS system and advances in computer technology have made it possible for the utility companies to implement synchronized sampling at all terminals of the protected lines. To achieve this, the phasor information of voltages and currents at different locations has to be acquired and evaluated to provide easy disturbance analysis and protection for the utility companies. This paper reviews and compares some recent patents regarding synchronous phasor measuring patents. Their possible applications are also discussed.
