Research on the HHT-Based Analysis Method of Tidal Power Generation Power Distribution Law

Tidal power generation technology has advanced quickly in recent years. In this study, the Hilbert-Huang transform (HHT) was used to examine electrical energy distribution law of tidal according time periods days, months, and years based on observed data for generation. Our analysis summarized as follows: span one day, motor ran 14 h before shutting off 10 h. The frequency 28 Hz, maximum voltage 259 V. swung twice a month, reaching its peak middle month trough at beginning. output fluctuated year, August, September, October February, March, April. investigation patterns, HHT transformation’s precision potency were confirmed.
