Widespread placement and high data sampling rate of current generation of Phasor Measurement Units (PMUs) in Wide Area Monitoring Systems (WAMS) result in huge amount of data to be analyzed and stored, making efficient storage of such data a priority. This paper presents a generalized compression technique that utilizes the inherent correlation within PMU data by exploiting both spatial and tem...

The concept of phasor measurement and its application in power system monitoring and control are introduced in this paper. The example of application of PMU in a Campus Wide Area Monitoring System (WAMS) is then elaborated. With the availability of synchrophasor data measurement, it makes possible to establish the power system monitoring by directly employing spectral analysis of power or phase...

Physical activity (PA) interventions constitute a critical component of cardiovascular disease (CVD) risk reduction programs. Objective mobile health (mHealth) software applications (apps) and wearable activity monitors (WAMs) can advance both assessment and integration of PA counseling in clinical settings and support community-based PA interventions. The use of mHealth technology for CVD risk...

This paper proposes a new adaptive underfrequency load shedding scheme (UFLS) to avoid frequency instability in electrical power system during abnormal wide area disturbances. The developed is based on online monitoring of the distance relay zone 3 decisions some tie lines using (WAMS) and SCADA/EMS systems, check rapidly reliably uncontrolled islanding conditions and, permit an automatic actio...

In this paper, we present a new method for the design of WAMS (Wide Area Measurement Systems). State estimation is responsible processing measurements in real time and providing complete secure database Wide Systems, therefore power system increasingly dependent on PMU measurements. The high cost communication infrastructure together with encouraged development placement solutions order to ensu...

This paper presents the fault detection technique in wide area power system network using Phasor Data Concentrator (PDC). Single line to ground (SLG) fault data of transmission line is processed using the WAMS technology. Phasor Data Concentrator (PDC) is primarily data collecting centres located at the control centre processing unit and is responsible for collecting all the PMUs data that is t...

In a modern power system, to realize the safe operation of units and maintain frequency stability network, various means modulation can be adopted. However, there are some deficiencies in real-time monitoring assessment management primary (PFM). To solve these problems, PFM online method based on “master–sub” control station model wide area measurement system (WAMS) is proposed as strategy supp...
