Continuous-Wavelet Transform for Fault Location in Distribution Power Networks: Definition of Mother Wavelets Inferred From Fault Originated Transients

Description:
The paper presents a fault location procedure for distribution networks based on the wavelet analysis of the fault-generated traveling waves. In particular, the proposed procedure implements the conti... see morenuous wavelet analysis applied to the voltage waveforms recorded during the fault in correspondence of a network bus. In order to improve the wavelet analysis, an algorithm is proposed to build specific mother wavelets inferred from the fault-originated transient waveforms. The performance of the proposed algorithm are analyzed for the case of the IEEE 34-bus test distribution network and compared with those achieved by using the more traditional Morlet mother wavelet.

Co-simulation Platform for the Analysis of Communication-based

Description:
The paper presents an ICT and power co-simulation platform for the analysis of the volt/var control and relevant optimization in medium voltage distribution feeders, achieved by means of a system of d... see moreistributed controllers coordinated via a shared band-limited digital communication network. The platform has been built by realizing the interface between two specific simulation environments: the Electromagnetic Transient Program EMTP-RV and the communication network simulator Opnet Modeller. The preliminary results provide basic indications on the expected performances of the considered communication-based strategies for different traffic congestion levels and load/generation dynamic variations.

SITL and HLA Co-simulation Platforms

Description:
Due to the necessity of developing analysis tools in the integrated ICT and power system domain, this paper describes and compares the architecture and configuration of two different ITC-power system ... see moreco-simulation approaches called SITL (System in the Loop) and HLA (High Level Architecture) Co-simulation platforms. Both platforms make use of the communication network simulator OPNET (Optimum Network Performance). As indicated by the names, the former operates in real time, in order to perform SITL simulations, whilst the latter is based on the HLA interface between OPNET and the power network simulation environment EMTP-rv (Electromagnetic Transient Program). We provide several details on their implementation and present their features by means of the results obtained for two test cases. The paper aims at clarifying the type of analysis that can be effectively carried out by using the two different platforms.
