Sn Engr. Yannian Yang, CRRC Zhuzhou Locomotive Co., Ltd
Mr. Yang Yannian has long been committed to the modularization of three-phase transformer windings and phasor connections, the integration of phasor diagrams and wiring diagrams, and the digitalization and informatization of phasor analysis of connection groups. By systematically studying the rules and laws of traditional line voltage phasor analysis, he innovatively proposed the rules of three-phase transformer connection group phasor analysis, enriched the basic theory of connection groups, and published six relevant papers in domestic core journals such as "Journal of Electrical Engineering" and "Transformer".
