Load flow, short circuit analysis and load point reliability for Data Centre power distribution networks

This paper is based on an investigation of load flow, short circuit analysis, and load point reliability of a data centres electrical power distribution network. A series of power system analysis software simulations were undertaken in order to determine the steady state behaviours of the power distribution system. Each load flow model investigated allowed a critique of model results for verification of critical bus-bar Voltage Security Index (VSI) and confirmation of acceptable Voltage limits, in-line with industry standards. Load flow studies highlighted optimal configurations for the electrical distribution networks, short circuit faults were simulated at multiple network locations for both nominal grid feeders, and mesh configurations with standby generators. Results from this research paper have provided recommendations on how to improve Operational Availability (AO) with suggestions given for optimal equipment configuration in terms of achieving improved Voltage security, limiting the required short circuit ratings of network equipment and investigating the improvement of load point reliability.
