Design and comparison of adaptive estimators for Under-balanced Drilling
Real time knowledge of total mass of gas and liquid in the annulus and geological properties of the reservoir is very useful in many active controllers, fault detection systems and safety applications in the well during ...
Stabilization control methods for enhancing the stability of wind farm integration via an MMC-based HVDC system
The subsynchronous oscillation (SSO) phenomenon may occur in a modular multilevel converter-based high-voltage dc (MMC-HVDC) transmission system for wind farm integration, which has already been observed in the real world. ...
Impact of time varying angular frequency on the separation of instantaneous power components in stand-alone power systems
The paper addresses the impact that time varying angular frequencies observed in electrical signals can have on the calculation and separation of components from the instantaneous electric power signal. Instantaneous power ...
