Phasor measurement unit (PMU) GPS receiver spoofing has been addressed in the recent literatures. Having spoofed GPS signals, the spoofer can inject bad data into power system control center and consequently the protection system will face serious problems. The existing anti spoofing techniques are all based on GPS signal analysis and are just able to detect spoofing. However, as PMUs are place...

In [4], we have studied the statistical properties and mono-fractality of the power system time series, voltage magnitude (V), frequency (f), and phase angle (θ). The power system data was measured using three Phasor Measurement Units (PMUs) installed at Baylor University, Harris Substation, McDonald Observatory in the Texas Synchrophasor Network [1]. Our analysis of several data sets has shown...

This thesis proposes a method to analyze power system stability by utilizing PMU measurements. As the current power system is operated close to its limits, stability is of high concern for both operators and customers. The implementation of phasor measurement units across the power system allows for accurate and fast stability monitoring and analysis. To address the application of PMU measureme...

Electric power system is a critical infrastructure and loss of its resilience and/or operability can lead to negative consequences for the national economy. Modern power systems based on sophisticated computer and communication technologies are characterized by elevated vulnerability to different types of unauthorized malicious access, i.e. cyber-attacks. Wide area measurement system which is b...

Optimal Phasor Measurement Unit (PMU) Placement (OPP) aims to reduce equipment costs while maintaining electrical systems observability. PMUs synchronized phasor data provide information with high quality and frequency enabling the implementation of faster than real-time state estimators. We applied Chemical Reaction Optimization (CRO) method at OPP problem, testing it successfully IEEE power s...

Distance relay is one of the most important protection element a transmission line used in schemes. Relay may malfunction if it not able to distinguish faults from system stressed conditions. This work mainly focusses on enhancing performance distance secured manner based data mining approach which uses two phases classification. Level 1 classifier identifies conditions like normal, fault, and ...
