Embodiment Construction
[0034]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] In view of the fact that the phase-locking of signals containing positive and negative sequence components requires two steps of positive and negative sequence identification and phase locking of the identification results, and the required time is the sum of the two steps, the embodiment of the present invention proposes a combination of positive and negative sequence A real-time electric quantity detection method and a dynamic phase-locking method for dynamic compensation of phase-lock synchronization errors.
[0036] The dynamic phase-locked synchronization method based on fast identificat...
