HARDWARE IMPLEMENTATION OF AN AUTOMATIC ADAPTIVE CENTRALIZED UNDER FREQUENCY LOAD SHEDDING SCHEME

Abstract

The under frequency load shedding (UFLS) mostly used in industry is a decentralized deterministic scheme designed to shed a pre-specified amount of load after a pre-determined time delay. It sheds the same amount of load from the same location irrespective of how fast the frequency drops and with no consideration to the disturbance location or dip in bus voltage. Recent studies focused on adaptive UFLS, but these studies are still based on software simulation. This study presents an implementation of a real time centralized adaptive UFLS scheme using industry grade hardware. It estimates the amount of load to be shed based on the rate of frequency decline and distributes the load to be shed among the load buses based on the voltage dip at these buses. The UFLS in this study is implemented using a real time digital simulator, Phasor Measurements Units (PMUs) embedded in the relays, a GPS clock and a synchrophasor vector processor (SVP). The load is modelled as a mixture of dynamic and static load. The implemented scheme restored the system frequency and voltage. The results emphasize its adaptability and suitability for implementation in industry.
