Implementation of Discrete Fourier Transform for Analysis of Electric Power Waves in a 2 MW Capacity Data Center with Synchronizer Panel

Abstract

The construction of an IT Data Center infrastructure is a top priority to advance a digital system that aids communication systems and electronic data storage. The IST (Integrated System Test) itself is a crucial testing process to ensure all equipment can function properly. One of the essential tests during the IST process is Load Change Over, where the full load in a Data Hall from the Duty system is transferred to the Backup system entirely with the assistance of the Synchronizer Panel. The LVSBU panel in the Data Center system is the first panel to bear the load when there is a transfer caused by system failure or power loss. When the LVSBU can handle the load properly without experiencing power loss, it secures the downstream system up to the IT Load. The Synchronizer Panel aids the load transfer process, reducing waveform distortions during load transfer. By using the Discrete Fourier Transform method, waveform distortions resulting from the load transfer from the Duty system to the Backup system can be observed and analyzed by changing the time domain to the frequency domain. The level of impact from using the Synchronizer Panel is highly significant compared to not using the Synchronizer Panel, which can be proven by the frequency graph and the low magnitude of disturbances, thus avoiding system failure in the Data Center.
