LOAD FLOW, SHORT CIRCUIT

Load flow studies are vital for commercial power systems to calculate fault analysis, short circuit and stability. We specialise in these studies for large industrial and commercial systems. Our analysis can map and highlight possible failure points, ensuring maximum uptime for production and protective maintenance.

LOAD FLOW INFORMATION

The configuration of the electrical distribution system changes over time to meet the needs of the various generation, manufacturing and operating processes. The alteration of an electrical distribution system configuration results in the operating characteristics and specification of the network changing.
For new and expanding facilities it is necessary to determine the predicted electrical load growth rate and investigate suitable connection points for future loads. Identifying suitable locations in the electrical network can be utilised for connection of electrical loads, identifying weak points, spare capacity and prediction of energy loss. This will allow the creation of a technically feasible strategy for the successful expansion of the network.

SHORT CIRCUIT INFORMATION

Anticipated maximum system fault levels will rise and fall depending on the system configuration and also the feeding arrangements. The connection of equipment such as transformers, UPS systems and generators to the electrical distribution system can increase the overall fault levels that can occur. It is imperative that fault studies are conducted at intervals throughout the lifetime of a facility or when significant alterations to the electrical distribution network take place, to ensure that equipment connected to the network will be capable of withstanding the anticipated system fault levels.

For new and expanding facilities it is necessary to determine the predicted electrical load growth rate and to investigate suitable connection points for the connection of future loads.

FEATURED CASE STUDY
World Renowned Data Centre - UPS Malfunction

Two large data centres in Dublin had seen malfunction of their UPS systems. Our studies were able to identify the level of harmonic distortion at each monitored location and assess any power quality events that may have been occurring. Using this data we could then propose mitigation solutions for the issues identified.

"Regular power system studies (monitoring and modelling) coupled with failure mode evaluation analysis (FMEA) helped identify a critical weak point within the facilities electrical distribution system. Power system health checks gave early warning, which helped prevent potential downtime and financial loss of €2 million. Moving from fire fighting mode to a controlled position that prevents potential downtime allows for a more efficient, profitable and safer site."
