Network Fault

The fault management process consists of several sub-tasks: fault location, fault isolation and service restoration. This work presents an assessment and evaluation of the practical aspects of the Medium Voltage (MV) Fault Locator at the Portuguese Distribution System primary substation. Eighty samples of incidents occurred at different MV network with different characteristics in Portugal were used to determine the time saving on the restoration process as well as the improvement on the quality of services indices. An economical assessment based of the use of the MV Distribution Network Fault Locator available in the Portuguese Primary Substation was done and discussed.

Emergency Mode

It is difficult to develop precise algorithms for determining fault locations for single-phase and double earth faults due to the features of emergency modes in medium voltage networks of 6-35 kV. The arbitrary configuration of electrical networks complicates the development of universal fault locations algorithms and, as a rule, technical solutions are limited by the need to use one-way measurements of emergency mode parameters. The article discusses new topology independent fault location algorithms that involve the use of the superposition method. The application of the proposed algorithms is justified by the results of simulation modeling and will allow implementation of calculating the distance to the fault in networks with isolated neutral with high accuracy.
