The OHL Rating project delivered enhanced line rating capability, improved integration with Asset Management’s other functions and better application support.
OCC also created facilities for data export to the National Grid Critical Unit Program.
The OCC LiveLoad application calculates the physical deformation on an overhead power line caused by suspending a maintenance trolley containing an engineer on the cable. Working on live cables from a trolley placed by helicopter will allow the National Grid Maintenance Delivery team to achieve significant efficiency savings.
National Grid chose OCC to develop and support "TRALC2", a desktop application which calculates the performance of National Grid's high voltage transformers as they are subjected to heavy electrical loads.
TRALC2 can be used to predict the performance of circuits in the next hours or minutes or it can be used months in advance to simulate the effects of planned maintenance. OCC delivered the first version of TRALC2 in 2000 and it is still being used, extended and supported.
OCC designed, developed and tested software to calculate the changing temperatures and electrical capacity of critical components in the high-voltage electricity transmission system in England and Wales. National Grid engineers have to balance the electrical load of components to ensure no component in the network overheats. Our solution was developed in a manner compatible with the National Control Centre infrastructure.
OCC developed a custom resource planning application for National Grid Gas to support their matrix-management. The Workplan system runs on the corporate intranet and was built to support existing staff working practices, realising the benefit of enhanced coordination with negligible training or disruption.
