Abstract
This paper presents a novel parallel RLC resonant load emulation technique for anti-islanding test. In an anti-islanding test setup, the load parameters R, L and C vary as they are dependent on the distributed generation (DG) rating. With the proposed emulation technique, the parameters R, L and C of the load can be controlled, while preserving the dynamic behaviour of the passive load, under all operating conditions. Two different current control methods for emulation are discussed. A two-level voltage source inverter (VSI) is used to emulate the RLC load. The results are verified using detailed time domain modelling in PSCAD/EMTDC for different type of DGs. The steady state performance of the proposed emulation technique is verified experimentally for different type of loads.
