Bursting Oscillation Characteristics and Improved AHODFC for DFIG and PMSG Combined Wind Farm

Energy Internet, EarlyView.
ABSTRACT Bursting oscillations occur in DFIG and PMSG combined wind farm under external disturbances and lead to the instability problems. To reveal the bursting oscillation characteristics and develop a suppression method, a fast‐slow dynamics analysis method and an improved adaptive high‐order differential feedback controller (AHODFC) based on ...

YOLO‐GDCNN: Real‐Time Operating Point Detection for Live Working Robots in the Power Industry

High Voltage, EarlyView.
ABSTRACT In the power industry maintenance, the capability of live working robots to detect and operate with power components in real time is paramount. This paper proposes a cascaded detection framework for real‐time detection of live working operation points, named YOLO‐GDCNN. The framework consists of two parts.

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...
