Power generator mechanical faults effects on electric power quality

2014 Electric Power Quality and Supply Reliability Conference (PQ), 2014
The principal objective of the paper is to establish the framework for power quality and vibration measurements assessment of hydropower generator. To meet the objective the set of measurements were performed on hydropower generating unit, using typical instrumentation like voltage analyzer for three-phase electrical networks, laser tachometer kit ...

Test pattern generation for power supply droop faults

19th International Conference on VLSI Design held jointly with 5th International Conference on Embedded Systems Design (VLSID'06), 2006
In deep sub-micron VLSI chips, when several transistors in physical proximity switch simultaneously, a substantial power supply drop, known as droop, may occur because of concurrent load on a via of the power grid. As a result of lower supply voltage, transistors may slow down. Such timing faults are termed as droop faults. Modeling of droop faults and

General-purpose fault detection for pulsed power applications

Conference Record of the 2000 Twenty-fourth International Power Modulator Symposium, 2000
A general-purpose electronic fault detection system has been designed for use with pulsed power experiments. Intended for use with a repetitively pulsed system, the fault detection electronics have the ability to shut down operations in the event of a fault, which would lead to damage if subsequent shots were allowed to proceed.

Fault-Tolerant Reconfigurable Low-Power pseudoRandom number Generator

2013 IEEE 16th International Symposium on Design and Diagnostics of Electronic Circuits & Systems (DDECS), 2013
The article describes a Fault-Tolerant Reconfigurable Low-power pseudoRandom number Generator (FT_RLRG) which integrates both Fibonacci and Galois LFSRs into a single hardware core. The design of FT_RLRG is of practical interest in testing triple modular fault-tolerant systems in the presence of single event upsets (SEUs), especially in case when the ...

Diagnosis of faults in wind power generation systems

2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA), 2016
Wind power does not pollute and is recyclable. The speed of the blades of a wind turbine speeds considerably affect the measured output power of the turbine. The speed of the tip of the blade must be set to maximize power output. The speed of the blade also significantly affects energy losses and the power coefficients.

MV Generator Ground Fault Arcing Power Damage Assessment

IEEE Transactions on Industry Applications, 2017
An industrial medium voltage (MV) system usually consists of multiple power sources such as utility tie transformers and generators. These are normally low-resistance grounding as shown in Fig. 1 . When a ground fault occurs at the generator stator, ground currents from its own neutral circuit and external power sources will flow into the fault and ...

Cascading Fault Prevention of Power Grid Based on Key Power Generation Nodes

2021
In the case of power grid cascading trip, this study puts forward a strategy to prevent cascading trip by changing the output of generator set. Firstly, according to the specific performance of the power grid under the cascade tripping, combined with the action behavior of the line current-type backup protection, and an expression equation for ...

Identification of mechanical faults in rotating machinery for power generation

2010 IEEE International Symposium on Industrial Electronics, 2010
Nowadays energy market requires flexibility in power production. This lead to operate power units in a discontinuous way and also machine types that are not normally designed to operate in such way, like steam and some gas turbo-generators, are forced to start and stop often during the day.
