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), 2006In 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, 2000A 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), 2013The 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), 2016Wind 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, 2017An 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
2021In 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, 2010Nowadays 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.

Blade Faults Diagnosis in Power Generation Gas Turbines
Volume 2: I&C, Digital Controls, and Influence of Human Factors; Plant Construction Issues and Supply Chain Management; Plant Operations, Maintenance, Aging Management, Reliability and Performance; Renewable Energy Systems: Solar, Wind, Hydro and Geothermal; Risk Management, Safety and Cyber Security; Steam Turbine-Generators, Electric Generators, Transformers, Switchgear, and Electric BOP and Auxiliaries; Student Competition; Thermal Hydraulics and Computational Fluid Dynamics, 2017This paper presents a case study in managing the dilemma of whether to resume or stop the operation of a power generation gas turbine with suspected blade faults. Vibration analysis is undertaken on the vibration signal of the gas turbine, to obtain an insight into the health condition of the blades before any decision is made on the operation of the ...

Risk evaluation of coupling fault for power generation equipment
2011 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2011Risk assessment is an important basis for maintenance decision-making. Based on the reliability analysis, trend prediction and condition evaluation, the paper defines a new running vulnerability, proposes a new analysis method of coupling faults consequence, and builds a risk evaluation model of power generation equipment.
