Comparison of Discretization Methods on the Second-Order Generalized Integrator Frequency-Locked Loop

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
As an indispensable part of traction converter control system, grid synchronization algorithm estimates phase angle of grid to ensure the system work in unit power factor. Second-order generalized integrator frequency-locked loop (SOGI-FLL) algorithm can be used as it has good dynamic response and steady-state accuracy, but its performance dependent on

Smart meter for the estimation of power quality indices based on second-order generalized integrator

Environmental Science and Pollution Research
With the increasing integration of renewable energy sources and nonlinear loads in the grid, it is necessary to compute energy and power quality parameters for monitoring as well as analyzing the power consumption indices (PCI) and power quality indices (PQI). Smart meters (SMs) can monitor the PCI and PQI at the consumer end.

Simple digital integration algorithm with saturation and drift elimination based Second-Order Generalized Integrator

2015 9th International Conference on Compatibility and Power Electronics (CPE), 2015
Integral operator and its digital implementation is a particular point in the estimation and monitoring algorithms using object observers. However, there appears saturation and drift problem on integration of harmonic signals. This paper proposes a simple algorithm based on Second-Order Generalized Integrator (SOGI) with effective elimination output ...

On some special general integrals of a linear differential equation of second order

Summary: A linear homogeneous differential equation of second order with polynomial coefficients is considered. The degree of each polynomial is equal to the order of the derivative of the unknown function which is multiplied by. We obtain conditions for the existence of the two polynomial solutions of the differential equation as well its general ...
