Project: Interaction Study in Manitoba
Client: Manitoba Hydro
TGS carried out a detailed sub-synchronous interaction study for the Manitoba Hydro system using our small signal stability assessment tool (TGSSR). Manitoba Hydro is currently adding a third HVDC bipole near to their existing two Nelson River Bipoles 1 and 2. The purpose of this study was to identify any potential controller interactions or SSR issues in the system. TGS Study services:
The study was performed for a relatively large system with 400 buses, three LCC HVDC bipoles, One VSC bipole and around 100 generators (about 5000 states). It was possible to identify an existing control oscillation problem of one of the HVDC bipoles and hence to verify the accuracy of the study.
