This paper presents a preliminary study of developing a novel distributed adaptive real-time learning framework for wide area monitoring of power systems integrated with distributed generations using synchrophasor technology. The framework comprises distributed agents (synchrophasors) for autonomous local condition monitoring and fault detection, and a central unit for generating global view fo...

Data quality of Phasor Measurement Unit (PMU) is receiving increasing attention as it has been identified as one of the limiting factors that affect many wide-area measurement system (WAMS) based applications. In general, existing PMU calibration methods include offline testing and model based approaches. However, in practice, the effectiveness of both is limited due to the very strong assumpti...

This paper describes the MedFasee project aiming at the development of a phasor measurement system (PMS) prototype and its applications for monitoring and control of power systems operation. A review of the state of the art, presented in the paper, provided the starting point for the project. A PMS simulator, developed to identify functionalities and specify system components, is presented. The...

Paper describes start-up of Croatian Academic Research Wide Area Monitoring System (CARWAMS), which is intended to support involvement of small R&D teams into fast developing synchronized measurement technology (SMT). Low voltage synchrophasors are collected by platform called WAMSTER, including handheld Phasor Measurement Units (PMUs) and GPRS data transfer to a dedicated served. Measurements ...

Phasor measurement Being able to determine phasors across the power system at a fixed point in time has the potential to solve these problems. One of the key components of future utility systems will therefore be Phasor Measurement Units (PMUs). PMUs rely on a GPS time signal for extremely accurate time-stamping of the power system information. A GPS satellite receiver (see box on page 60) prov...

This paper presents a procedure by which new PMU locations can be systematically determined in order to render an observable system. The procedure is then extended to account for cases of loss of a single phasor measurement unit (PMU). Buses with zero and non-zero injections, and branches with power flow measurements are also accounted for in this generalized procedure. Several cases involving ...

Such measurements also could enable effective realtime system monitoring and control, which are considered to be the key to preventing wide-sc...

This paper investigates a possibility for estimating rotor angles in the time frame of transient (angle) stability of electric power systems, for use in real-time. The proposed dynamic state estimation technique is based on the use of voltage and current phasors obtained from a phasor measurement unit supposed to be installed on the extra-high voltage side of the substation of a power plant, to...

Complex power systems need better observability and visualization capabilities to handle critical situations effectively. Synchro-phasor measurements provide intra second visibility to power system dynamics and enable faster control actions. A Phasor Measurement Unit (PMU) measures the voltage and current phasors (angle and magnitude) at a bus in a power system. In the literature, many methods ...
