Performance Analysis of Sampled Values-Based Protection in IEC 61850 Process Bus Networks
… presents a complete test bench for evaluating sampled values-based protection schemes and measures their efficacy under several different operating conditions. It is shown that the novel system operates correctly for the situations it is expected to, with minimal latency compared to traditional …

Passive Rational Fitting of a Passive Network Transfer Function From Its Real Part
… network transfer function that makes use of sampled values of the transfer function's real part at a set of frequencies over the bandwidth of interest. For passive networks, real-part sufficiency describes the fact that the self and mutual impedance or admittance is uniquely defined in terms …

Inference Plans for Hybrid Probabilistic Inference
… and variables that are represented by sampled values, and in general, they make no guarantee that the partitioning is optimal. In this thesis, I present inference plans, a programming interface that enables developers to choose a specific partitioning of random variables during hybrid …

Data Trustworthiness in Synchronized Power System Measurements: Algorithms and Methodologies
… detection approaches in synchrophasor and sampled values data streams. The analysis extends to Merging Units (MUs) and Phasor Data Concentrators (PDCs), exploring their role not only as data providers but also as active elements for event detection and situational awareness. The proposed …

A universal centralized protection scheme for feeders of AC microgrids using IEC-61869-9 digital instrument transformers
This thesis underscores the escalating importance of microgrids powered by renewable energy sources and inverters in modern power systems. Despite offering significant environmental and economic advantages, their decentralized and dynamic nature poses unique protection challenges. Traditional …

Matroid prophet inequalities and Bayesian mechanism design
… in expectation, as a "prophet" who knows the sampled values of each random variable and can choose the largest one. We generalize this result to the setting in which the gambler and the prophet are allowed to make more than one selection, subject to a matroid constraint. We show that the …

Algorithms for the synchrophasor measurement in steady-state and dynamic conditions
… architecture based on process bus and sampled values synchronized with IEEE 1588-2008 is proposed, so that voltage and current signals are acquired by a Merging Unit device, while the PMU signal processing is performed on a IED (Intelligent Electronic Device), in compliance with IEEE …

Crystal filter tuning using machine learning.
… with the following two functions: (1) Required values of features are extracted from the filter waveform and passed to the expert system which determines the component to adjust and the direction to turn, or the end of the tuning. (2) Sampled values of the waveform are extracted and passed to a …
