Improved damper cage design for salient-pole synchronous generators [PDF]
, 2016 The benefits of implementing a damper winding in salient-pole, synchronous generators are widely known and well consolidated. It is also well known that such a winding incurs extra losses in the machine due to a number of reasons. In order to improve the

Algae control for hydrogeneration canals [PDF]
, 1997 The purpose of this Cooperative Research and Development Agreement (CRADA) was to assess and develop control practices for nuisance algae growth in power canal that delivers water to hydro-generation facilities. This growth results in expenditures related not only to lost generation but also labor and materials costs associated with implementing ...

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.By studying the electromagnetic force law of the stator tooth wall and the key points of the stator tooth tip under different loadings, the key parts of the stator tooth wall subjected to the electromagnetic force shock are found out. What's more, the force change law of the damping strip is obtained through analysing the force of the damping tooth ...
