DYNAMIC MODELING AND EIGEN ANALYSIS OF ADJUSTABLE-SPEED PUMPED STORAGE UNIT IN PUMPING MODE UNDER POWER REGULATION

Dynamic Modeling and Eigen Analysis of Adjustable-Speed Pumped Storage Unit in Pumping Mode Under Power Regulation

The main merit of grid-connected adjustable-speed pumped storage unit (ASPSU) is the capability to control the pumping power flexibly, which contributes to active power balance in power system operation.Physics-based dynamic modeling of ASPSU in pumping mode under power regulation is the foundation of the quantitative analysis on its transient perf

Comparative features of infections of two Massachusetts (Mass) infectious bronchitis virus (IBV) variants isolated from Western Canadian layer flocks

Abstract Background Infectious bronchitis virus (IBV) is one of the leading causes of mortality and morbidity in chickens.There are numerous serotypes and variants, which do not confer cross protection resulting in failure of currently used IBV vaccines.Although variant IBV isolates with major genetic differences have been subjected to comparative
