Market power monitoring under open access system
In this paper, an engineering procedure is proposed for complete market power monitoring under open access system. Market power monitoring of any given system or network is done by using market power assessment and market power indices. For any given network, market power assessment is to identify which generation company (GENCO) raised their prices when the demand in the concerned area is ...

Characterisation of power quality disturbances based on wavelet transforms
This paper presents a new technique for detecting and characterising disturbances in power systems based on wavelet transforms. The voltage signal under investigation is often corrupted by noises, therefore the voltage signal is first denoised using wavelet thresholding and then wavelet transform is applied to the denoised signal. Using the first-level detail wavelet coefficients, the voltage ...

Electric power systems real-time monitoring and control
In recent decades, several improvements have been achieved in power system operation and control. The evolution was mainly in the development of computational and communication systems. Both areas allowed the analysis of complex models of power system operation and control that resulted in a more flexible system controlled in almost real-time mode. All these improvements favoured the change of ...

Online condition monitoring of electrical power system imbalance
Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

Wavelet feature–based modular neural network for detection and classification of power quality disturbances
Disturbances such as voltage sag, swell, interruption and harmonics are very typical in a power system. Power quality monitoring should be capable of identifying these disturbances to initiate mitigation action and protect sensitive loads. This paper presents wavelet–neural network–based detection and classification of power quality disturbances. Wavelet transform has the ability to analyse ...

Protect Your Data Center During Power Outages and Heatwaves
IT Infrastructure located in a hot climate is a challenge. This is exasperated when heatwaves occur. Abnormally hot temperatures present considerable challenges to your Data Center. Protect Your Data Center During Power Outages and Heatwaves. Heatwaves increase the demand placed on public power grids. The increased demand means power grids are more subject to failure. It is therefore ...

Modernisation of the CDTN IPR-R1 TRIGA reactor instrumentation and control
In the IPR-R1 TRIGA control room, analogue system based on relay-based logic was used, and mechanical strip chart recorders are used to measure, monitor and record the operational parameters. The same variables of the original control system are measured, although the reactor power was upgraded to 250 kW. For this new power the fuel heat transfer becomes important and new parameters should be ...

Singular system analysis of the Local Power Range Monitor (LPRM) readings of a Boiling Water Reactor (BWR) in an unstable event
Singular system analysis is a successful technique to separate oscillating components from a given signal. A methodology is proposed to apply this technique to the signals obtained from the LPRMs of a boiling water reactor core and extract the contributions of the in-phase oscillation and the out-of-phase oscillations from the LPRM readings during an unstable event. This methodology has been ...

Monitoring the Bavarian nuclear power plants online applying a Lagrangian model
In 1997, the Monitoring System for Nuclear Power Plants (KFÜ) - located in the Bavarian office of environmental protection - was upgraded. The change included replacing the Gaussian plume model by a numerical dispersion model based on the Lagrangian theory. The KFÜ system allows the assessment of the doses workers receive in routine and emergency operation. Improvements of the new monitoring ...
