“…However, accurate calculations on harmonic flows cannot be implemented as conveniently as normal power flow, due to that high-order harmonic measurements should be synchronised first to ensure that collected data reflect the same snapshot of the network. To overcome these difficulties, synchronised harmonics is proposed [22,23], the concept of which can be illustrated in Fig. 1.…”

“…Synchronised harmonics that applies GPS to synchronise harmonic monitoring of power systems has been developed since last decade [22,23]. Although the high cost has limited the utilisation of synchronised measurements at distribution level at first, but recent achievements across electronics sector have driven the cost of PMUs dropped dramatically in price.…”

“…We deployed a MySQL database to store these model definitions and implement the model base. To improve the ability to replicate model-based research, we implemented our framework using LAMP architecture to build the modelling management features, including parameterizations and runtime control [24,58,59]. LAMP consists of several open source projects that provide a complete and robust solution for the operating system, the web server, the database, and a scripting language.…”

Abstract:The model environment is a key component that enables a virtual geographic environment (VGE) to meet the scientific requirements for simulating dynamic phenomena and performing analyses. Considering the comprehensiveness of geographic processes and the requirements for the replication of model-based research, this paper proposes a model base framework for a model environment of a VGE that supports both model construction and modelling management, resulting in improved reproducibility. In this framework, model management includes model metadata, creation, deposition, encapsulation, integration, and adaptation; while modelling management focuses on invoking the model, model computation, and runtime control of the model. Based on this framework, to consider the problem of ever-worsening air quality, we applied the Linux-Apache-MySQL-Perl stack plus Supervisor to implement the model base to support a VGE prototype using professional meteorological and air quality models. Using this VGE prototype, we simulated a typical air pollution case for January 2010. The prototype not only illustrates how a VGE application can be built on the proposed model base, but also facilitates air quality simulations and emergency management.

“…Particular applications can be found in [3] where an industrial Programmable Logic Controller (PLC) on a web-based platform is used for transient detection of microgrid systems and in [4] where frequency fluctuations of high voltage transmission grid are monitored for the individuation of generator tripping. Some systems are designed to reach the maximum stability using commercial systems or PQ analyzers for the data acquisition [1,5,6,7,13], but often this choice reduces the flexibility and increases the costs, especially in the case of a large number of measurement points (MPs).…”

Abstract" distributed web-based system for temporal and spatial power quality analysis has been realized and tested. Connecting by internet local instruments able to perform high accuracy measurements in real time, the Power Quality information, locally measured, can be sent to a remote central server which aim is to plot them and stored the data for future analysis. The remote instruments have been realized, tested and placed in two Italian cities, Palermo and Rome, where actually work while the server works in Rome. The web application allows to select the single instrument and to show its stored PQ information.
