Investigation of Relationship between Voltage and Nondetection Zone of OUV/OUF of Local Islanding Detection Techniques

M. Yingram and S. Premrudeepreechacharn
Abstract—The objective of this paper is to investigate relationship between voltage and nondetection zone of OUV/OUF of local islanding detection techniques of distributed generation in electric power system network. This paper shows experimental results of inverter-based DG and synchronous-based DG with parallel RLC load that causes the most difficulty in detection. The experiments have shown that, case of inverter-based DG: variation of active power associated with variation of off-grid voltage at VPCC, case of synchronous-based DG: variation of off-grid voltage at VPCC was not associate with variation of active power but variation of off-grid voltage at VPCC associated with variation of reactive power. Nondetection zone of OUV of synchronous-based DG are very possibility that Q can more than -9.6 MVAR or Q can less than 3.6 MVAR which they can affect the VPCC to outside of normal voltage range when islanding condition is happen.

Index Terms—Islanding detection, distributed generation, grid-connected.
