The phase-locked loop (PLL) algorithm uses the external input reference signal to control the frequency and phase of the internal oscillation signal of the loop; thus, the control signal and the ...

This paper presents a new three-phase phase-locked loop (PLL) system that primarily estimates the phase angles, frequency, and magnitudes of the a three-phase input signal and also provides a filtered ...

The New Lock at the Soo project is being built in 3 phases. Phase 1 (Upstream Channel Deepening) was completed in 2022 and Phase 2 (Upstream Approach Walls) was completed in 2024.
