The effect of different control modes and mixed types of DG on the non-detection zones of islanding detection

CIRED 2012 Workshop: Integration of Renewables into the Distribution Grid, 2012
Loss of mains protection (LOM) is among the most challenging issues related to the integration of distributed generation (DG). This paper presents simulation studies on the effect of multiple DG units on LOM protection. The results reveal an operational risk related to the active LOM detection methods.

Experimental Investigation on Non Detection Zones of Active Frequency Drift Method for Anti-islanding

IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society, 2007
The islanding effect of utility-interactive photovoltaic (UIPV) system may cause hazards for the grid equipment, and even danger to grid personnel. Therefore, reliable islanding detection is one of the crucial factors to connect grid for UIPV system. Over the years, a number of research works have been concentrated on the techniques of non-detection ...

Instability criterion to eliminate the Non-Detection Zone of the Sandia Frequency Shift method

2009 IEEE/PES Power Systems Conference and Exposition, 2009
Sandia Frequency Shift (SFS) islanding detection method is considered amongst the most efficient islanding detection methods that possesses small Non-Detection Zone (NDZ) for inverter based Distributed Generation (DG). The NDZ of the SFS depends to a great extent on its design parameters.

Power Equations and Non-Detection Zone of Passive Islanding Detection and Protection Method for Grid Connected Photovoltaic Generation System

2009 Pacific-Asia Conference on Circuits, Communications and Systems, 2009
Islanding detection and protection is an important concern for grid connected photovoltaic (PV) power generation system due to personnel and equipment safety. Over/Under Voltage Protection (OVP/UVP) and Over/Under Frequency Protection (OFP/UFP) are basical inverter resident passive islanding detection method (IDM) for detecting an islanding condition ...
