“…17,18 It is shown that the real-time performance of the TDTL compares favorably with the simulation results obtained from the MATLAB/SIMULINK model. The synthesis process of the prototype system used Xilinx System Generator to generate the necessary hardware description language (HDL) for the device-optimized block-set from within SIMULINK.…”

“…In addition, the system has a controllable variable time delay module which is used in conjunction with the PV source voltage to emulate the functionality of the digital controlled oscillator (DCO) used in the conventional TDTL system. [16][17][18] A continuous sinusoidal signal yðtÞ, representing the grid voltage, as defined by Eq. (1) with a phase offset xðt À t o Þ relative to the PV voltage waveform PðtÞ is received by the proposed system, through an appropriate interface, as depicted in Figure 2.…”

“…16 There are two main types of non-uniform DPLLs; the zero crossing DPLL (ZCDPLL) and the digital tanlock loop (DTL). [16][17][18] Despite its simplicity and ease of implementation, the ZCDPLL has a major drawback due to its sensitivity to variation in the input signal power, which degrades its performance. This paved the way for the DTL to stand as an attractive alternative.…”

The system which is based on the time-delay digital tanlock loop was simulated using MATLAB/ SIMULINK and was tested by subjecting the grid voltage to various perturbations similar to those which can occur in a real power system, such as voltage sags and nonlinear distortion of the grid voltage waveform. Results indicate that even in the presence of such perturbations the system achieved and/or re-gained synchronization within 100 ms. The proposed system is all-digital and can be readily implemented using a field programmable gate array and easily embedded into a power inverter. V C 2012 American Institute of Physics.

Abstract. This paper presents a new circuit topology of a phase-locked loop that can be used for synchronising a singlephase wind turbine generator (WTG) with the low voltage utility grid. The circuit is based on the time-delay digital tanlock loop (TDTL) architecture and was modelled and simulated using Simulink/MATLAB. The results presented demonstrate the ability of the circuit not only to synchronise a WTG with the grid, but also to re-gain synchronization following a sudden disturbance in the grid voltage. The simulated disturbances included a ramp and a multi-step change in the phase of the grid voltage waveform.
