Analysis and Treatment of Generator Vibration Faults in a Power Plant

IOP Conference Series: Earth and Environmental Science, 2020
Abstract This paper presents a detail research on a vibration high fault after overhaul occurred on a generator. During the overhaul, the generator rotor is returned to factory for processing and replaces section across the line of the generator excitation end.

Fault-Tolerant Operation of an Open-End Winding Five-Phase PMSM Drive with Inverter Faults [PDF]

, 2013
The authors would like to thank the ADEME for the funding of the MHYGALE project.Multi-phase machines are known for their fault-tolerant capability. However, star-connected machines have no fault tolerance to inverter switch short-circuit fault.

March AB, March AB1: new March tests for unlinked dynamic memory faults [PDF]

, 2005
Among the different types of algorithms proposed to test static random access memories (SRAMs), March tests have proven to be faster, simpler and regularly structured. New memory production technologies introduce new classes of faults usually referred to

Impact of large-scale photovoltaic-energy storage power generation system access on differential protection of main transformer under symmetrical faults

Frontiers in Energy Research, 2023
The low voltage ride-through (LVRT) requirements demand large-scale photovoltaic (PV) power generation system remain connected to the grid during faults. It results in considerable impact on the characteristics of fault current.

Automatic March tests generation for multi-port SRAMs [PDF]

, 2006
Testing of Multi-Port (MP) SRAMs requires special tests since the multiple and simultaneous access can sensitize faults that are different from the conventional single-port memory faults.
