In the perspective of a capillary power system monitoring, measurement transducers must have larger and larger bandwidth and accuracy, due to proliferation on power grids of new power quality phenomena. Various types of voltage transducers, based on different operation principles, have been realized; in particular, those based on voltage dividers and optical insulation with digital communicatio...

This paper gives an overview of the smart grids developments, seen from a power-quality viewpoint; describes the main relations between smart grids and power quality, and goes into some detail for some of the aspects. Different types of real and virtual energy storage are distinguished. Power-quality monitoring in the smart grid is discussed in detail. Further aspects discussed in the paper are...

With the electric industry undergoing change, increased attention is being focused on power supply reliability and power quality. Power providers and users alike are concerned about reliable power, whether the focus is on interruptions and disturbances or extended outages. Monitoring can provide information about power flow and demand and help to identify the cause of power system disturbances....

Water-quality monitoring technology has been taken a great attention in aquaculture because of increasing aquatic products and impact of food safety vicious incidents. In order to meet the technology requirements of water-quality monitoring in multi-parameter, dynamic, and networked monitoring, a water-quality dynamic monitoring system was developed to monitor multi-parameter water-quality vari...

Nonintrusive load monitoring (NILM), sometimes referred to as load disaggregation, is the process of determining what loads or appliances are running in a house from analysis of the power signal of the whole-house power meter. As the popularity of NILM grows, we find there is no consistent way researchers are measuring and reporting accuracies. In this short communication, we present a unified ...

active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. this paper proposes a control scheme based on the instantaneous active and reactive power. the inverter of this active filter is a three-phase, two-level converter. space vector technique is used as modulators and pattern genera...

Problems derived from the power quality aspects of a power grid are turning the monitoring and diagnosis tasks into an appealing field for electric power researchers. This interest is mainly founded on the great importance of providing highly reliable power grids, but also because of the relatively simple task (computationally speaking) required to accomplish the measurements. Despite its poten...

This paper presents an electric power monoring based on Artificial Neural Network (ANN) for the nuclear power plants. The Recurrent Neural Networks (RNN) and the feed-forward neural network are selected for the plant modeling and anomaly detection because of the high capability of modeling for dynamic behaviors. Two types of Recurrent Neural Networks (RNN) are used. The first one Elman type of ...

the wide availability of data on air pollutant emissions, the knowledge already achieved on theset of chemical and photochemical reactions in the troposphere, the ability to access real time weatherconditions at the local scale that determine the transport and transformation of gases and aerosol, now make it possible to obtain credible and reliable predictions, retrospective analyses and/or fut...
