An Improved Phase-locked Loop Based on Second-order Generalized Integrator

Under ideal grid voltage conditions, single synchronous reference frame phase-locked loop (SSRF-PLL) enables fast and accurate phase/frequency detection, however, abnormal grid voltage conditions highly degrade its performance. To overcome this drawback, it presented an improved PLL based on second-...
