New energy Photovoltaic｜PV Power station Case
Photovoltaic power generation converts luminous energy from PV modules into DC power, which is then transformed into AC power via inverters and fed into power grids, constituting one of mainstream clean energy generation forms in China. Subject to illumination variation, cloud cover shielding and temperature change influences, power generation outputs of PV power stations feature randomness and fluctuation. High frequency switching operation of inverters generates massive harmonics and high frequency clutter, readily inducing risks of voltage flicker, grid connection inrush currents and system resonance and impairing grid connection acceptance results and power generation yields of power stations. As core supporting components of inverters and box type transformers, special purpose transformers and reactors for PV applications realize functions of step up voltage conversion, galvanic isolation, harmonic filtering, grid connection inrush current suppression and grid resonance damping. Custom developed for bidirectional power flow, outdoor wide temperature range, dust laden and humid conditions, our products feature bidirectional power transmission capability, harmonic over heating resistance, outdoor weather resistance and good anti magnetic saturation performance compared with general purpose industrial products. They resolve pain points including difficult grid connection of PV power stations, non compliant power quality and high equipment failure rates and guarantee stable and efficient grid connected power generation for centralized and distributed PV power stations.
