An improved second order generalized integrators phase locked loop for flexible DC transmission

An improved second order generalized integrators phase locked loop for flexible DC transmission

Accurate and fast phase locking is the primary condition for flexible DC transmission to realize reliable control. When the power grid is unbalanced or contains high-order harmonics, the traditional second order generalized integrator (SOGI) itself has the defect of strong dependence on the input si...
