Abstract: To improve grid-connected inverter operation performance, a power oscillation and current harmonic suppression coordinate control strategy that considers the problem of overcurrent is proposed in this work. First, the ...

Abstract: An air-entrained vortex is a complicated and negative phenomenon in a pump sump. Due to the unsteady vortical and two-phase-flow properties, its prediction is challenging. In this paper, advanced turbulence models sensitive ...

Abstract: Renewable energy has the characteristics of fluctuation and intermittence due to environmental conditions; the fluctuation of output power affects the operation of the power grid. To combat these fluctuations, a control ...

Abstract: Separate-layer injection technology is a highly significant approach for enhancing oil recovery in the later stages of oilfield production. Both separate-layer and general injection information are crucial parameters in ...

Abstract: Wall-attached vortices in pump intake commonly appear and damage the stability of the whole pump station. Revealing the effects of these vortices on the pump performance is crucial for safe operation. In this paper, ...
