A Novel Islanding Detection Method Based On Rate of Change of Reactive Power
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
Micro-grids usage among consumers has become a new attraction due their several of advantage. Its major function is to ensure the stable operation during the fault and a variety of utility grid disruption. Since the utilization of micro-grid became common, the correct application and operation of micro-grid is important and significant. One of the main challenges in micro-grids operation is islanding detection methods. There are several methods that handles the islanding detection that each, one have advantage and some disadvantage. This paper presents and investigates a method based on rate of change of reactive power for islanding detection. The passive algorithm in this paper has low cost operation, however it got the higher NonDetection Zone (NDZ) and slower response time compare some active methods. The micro-grid simulation in a ring network is modelled in Matlab/Simulink program and the results of the monitoring are discussed as well.
