Eduardo Lorenzetti PelliniThis paper presents the development, simulation results, and field tests of an automated fault location system for primary distribution networks. This fault location system is able to identify the most probable fault locations in a fast and accurate way. It is based on measurements provided by intelligent electronic devices (IEDs) with built-in oscillography function, installed only at the substation level, and on a database that stores information about the network topology and its electrical parameters. Simulations evaluate the accuracy of the proposed system and the experimental results come from a prototype installation.

This research presents the development and implementation in a computational routine of algorithms for fault location in multiterminal transmission lines. These algorithms are part of a fault-location system, which is capable of correctly identifying the fault point based on voltage and current phasor quantities, calculated by using measurements of voltage and current signals from intelligent electronic devices, located on the transmission-line terminals. The algorithms have access to the electrical parameters of the transmission lines and to information about the transformers loading and their connection type. This paper also presents the development of phase component models for the power system elements used by the fault-location algorithms.

This paper presents a proposal for functional testing of protection and automation systems based on the IEC61850 standard. The proposed methodology is based on the development of tests scenarios which properly represent the actual systems and their operative conditions. It includes the selection of hardware and software that are used to simulate the operational events and acquire data for further analysis. This methodology was developed to evaluate the protection and automation systems of large-sized substations mainly regarding the interoperability between intelligent electronic devices of different manufacturers. This paper explains in detail the proposed methodology and an actual case study.

Giovanni Manassero JuniorThis paper proposes a non-contact method for fault location in transmission lines, which is based on magnetic fields produced by current signals measured using magnetoresistive sensors installed only at transmission line terminals, under the phase conductors of the first transmission tower at both terminals or at the substations portals. The proposed method uses the Extended Kalman filter to process these measurements and is based on a travelling wave approach in order to perform the fault localization. This paper also describes the implementation and testing of the method, firstly introducing its overview, followed by an analysis of the magnetic fields produced by the current signals, as well as considerations on their measurement; secondly, detailing the Extended Kalman filter and the travelling wave approach; and, finally, presenting the results of the method with regards to simulations built using EMTP/ATP to evaluate its robustness under different conditions varying the fault resistance, fault inception angle, phases involved and fault location. The results indicate that the proposed method is robust and accurate.

Giovanni Manassero JuniorThis work presents a time-domain protection solution based on integrated quantities. In order to provide a deterministic differential protection method, two algorithms that use voltage and current samples to estimate energy flow and reactive power entering a protection zone are used. The algorithms work by integrating time-domain measurements and generated signals in order to achieve stable quantities that are afterwards used for protection. After the description of the differential fault identification method, a phase selection scheme is presented in order to provide a complete protection solution. The proposed system was extensively tested on simulations based on data from five actual transmission lines, the power systems were simulated using ATP/EMTP and the protection was implemented using GNU Octave software. Thousands of cases were generated using automation scripts in order to validate the protection algorithms. The work also describes the conducted sensitivity test, which includes current transformer saturation, and unsynchronized measurements. The proposed solution proved itself secure and dependable under the tested conditions.
