Air friction losses in PM BLDC motor with external rotor operating as kinetic energy storage system
2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC), 2021Moment of inertia of motor with external rotor is much higher than this moment for motor with internal rotor and identical power rating. This characteristic may be utilized for designing kinetic energy storage using electric motor. Problems occurring when brushless dc motor (PM BLDC) with external rotor is employed as kinetic energy storage are ...

Equivalent Inertia Estimation of Power System Based on Kinetic Energy Theorem
2023 IEEE International Conference on Power Science and Technology (ICPST), 2023The accurate estimation of power system equivalent inertia is crucial for rational planning of grid-connected capacity for new energy and for ensuring the safety and stability of the system frequency. This study proposes a novel method for estimating the

Though simple and fast, bulk-flow models (BFMs) for gas labyrinth seals (LSs) often predict the mass flow inaccurately. The BFM models rely on classical Neumann's equation model to characterize the flow through a labyrinth tooth.

International Conference on Renewable Power Generation (RPG 2015), 2015
Letting the interconnected wind farm actively provide spinning reserve control ability on the electrical power system has become a new challenge to both the dispatching departments and wind farm operators. In this paper, methods such as taking rotor inertia kinetic energy of the Variable Speed Wind Turbines into Wind Farm Spinning Reserve Capacity are ...

The kinetics of the order–disorder transition in solid carbon monoxide by a tunneling mechanism are considered. The rate of the transition is found to be much smaller than the rate of barrier penetration. An estimate of the rate is made using the best current estimate of the twofold barrier to end-for-end rotation in solid carbon monoxide; it appears ...
