Abstract

Distributed Generation (DG) is gradually increasing in Distribution Grid, both in LV, MV and HV, creating new challenges to utilities. One of them is the capacity to detect an unwanted islanding operation. As seen in recent studies, especially when the load demand is similar to generation, traditional anti-islanding detection protection functions, that rely mainly on frequency deviations and voltage variations at the interconnection point may present a low performance.To suppress this constrains, new approaches are being tested, such as using the voltage phase angle difference between the main grid and the DG side. For the purpose of assessing the effectiveness of this approach EDP Distribuição (EDPD) decided to install a set of micro Phasor Measurement Units (µPMU) in the Interconnection point of EDP Distribuição’s Energy Storage System (ESS) that is connected to a MV 15kV grid and has the capability of being able to create an 15kV network island automatically in case of an outage in the feeder or manually.In this paper, voltage phase measurement is used as a parameter for islanding detection and some real islanding situations detected, using this method, are shown. Also, this paper presents some difficulties encountered during the installation and operation of µPMUs.
