in this paper, a new method based on branch placement for the optimal positioning of phasor measurement units (pmus) in power systems is proposed. in this method, the pmus are in type of single-channel and are installed at the beginning of the branches. therefore, they are able to measure the bus voltages. also, the installation of the pmus on the branches increases the security of observabilit...

monitoring is an essential and inseparable tool for every industrial automation system.  in advanced monitoring, in addition to representation of the process conditions, fast identification and removing of the faults in different critical parts of the system is indispensable. distributed control systems (dcs) are an integral part of the current automation systems and hence, advanced monitoring ...

measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

Abstract: The risks of alternating current (AC) corrosion and overprotection increasingly demand new criteria forcathodically protected pipelines. To assess the risk of AC corrosion, new cathodic protection (CP) criteria have beenproposed based on DC/AC current densities measurements using coupons. The monitoring system designed for thisproject was based on the instant-off method, with steel co...

Condition monitoring is the foundation of a condition based maintenance (CBM). To relate the information obtained from the condition monitoring to the actual state of the system, it is usually required a stochastic model. On the other hand, considering the interactions and similarities that exist between CBM and statistical process control (SPC), the integrated models for CBM and SPC have been ...

in this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. this technique uses synchronized phasors measured by phasor measurement units (pmus) in a wide-area measurement system. in order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...
