Mandan Project Transmission Planning Studies

A member of ERG was responsible for the performance of extensive large area load flow, transient stability and inter-pool transfer studies concerning the MANDAN Project, a proposed 700 mile long, ±450 kV bipolar, three terminal, EHVDC transmission line between Manitoba, Canada and Hoskins, Nebraska. In addition, transient network analyzer studies were performed. This proposed $900 million project presented critical regional reliability issues as result of its planned design to nominally transfer 2000 MW on a seasonal diversity basis between the Manitoba Hydroelectric Board and Nebraska Public Power District. A member of ERG coordinated the study efforts with RTE-ASEA of Sweden, the planned manufacturer of the Project’s thyristor valves and invertor/convertor equipment.
