Paper on improving DFIMs earns award from IEEE Transactions

Professor Longya Xu’s scholarly paper on a new high frequency injection method for doubly fed induction machines (DFIM) has received the first-place award for Best Society Transaction Paper Award for articles published in the IEEE Transactions on Industry Applications journal. Read the article.

The paper was co-authored with graduate students Ernesto Inoa, Yu Liu and Bo Guan.

Xu said DFIMs are widely used in wind farms for generating mega-watts of renewable energy, but have room for advancements that could yield better performance and lower costs.

The paper presented a new technology of sensorless control for a grid-connected DFIM. The innovation allows the DFIM system to be more reliable in operation, more intelligent in dealing with faulty conditions, and lower in costs.

The award is given annually to the best papers published in IAS Transactions during the previous year. Xu said the basis of judging includes originality, timeliness, contribution and clarity.
