The present invention discloses a modular intelligent combined wind power converter and a control method thereof. The modular intelligent combined wind power converter comprises separate bridge arm power units, wherein a plurality of the bridge arm power units are connected in parallel to form a high-capacity bridge arm power module, three bridge arm power modules form a three-phase full-controlled bridge power module, and the three-phase full-controlled bridge power module comprises an electric reactor, a capacitor, a fuse and a circuit breaker to form a basic converter module, and the basic converter module forms a high-capacity wind power converter through a modular intelligent combination method.

Modular intelligent combined wind power converter and control method thereof

An oxygen evolution reaction (OER) electrocatalyst for acidic media comprises a metal oxide structure comprising a pyrochlore phase of chemical formula ABO, wherein A comprises one or more A-site metals, B comprises one or more B-site metals, and 6.0&#x2264;n&#x2264;7.3. The metal oxide structure exhibits a mass current density of at least about 20 A/g at an over-potential of 0.22 V in 0.1 M HClO. According to another embodiment, an electrocatalyst for acidic media comprises a porous metal oxide structure having particulate walls separating a plurality of pores, where each particulate wall comprises interconnected primary particles. The porous metal oxide structure comprises a pyrochlore phase of chemical formula ABO, wherein A comprises one or more A-site metals, B comprises one or more B-site metals, and 6.0&#x2264;n&#x2264;7.3.
