7 If the 345 kV Nova Scotia - New Brunswick intertie trips while exporting, the parallel 8 138 kV lines can be severely overloaded and potentially trip, causing Nova Scotia to 9 separate from New Brunswick. If this happens, the Nova Scotia...

AI summary If the 345 kV Nova Scotia - New Brunswick intertie trips while exporting, the 138 kV lines could overload and cause Nova Scotia to separate from New Brunswick, leading to frequency instability and equipment damage. NS Power uses a fast-acting SPS to mitigate this risk by adjusting generation.

Steady State Analysis was carried out using Python scripts within PSS®E software version 33.7. The scripts simulate base case and a wide range of single contingencies, with the output reports summarizing bus voltages or branch flows that e...

AI summary Steady-state simulations using PSS®E version 33.7 were conducted to assess system reliability, including contingencies up to 2021. The analysis incorporated modifications leading to the Maritime Link project's completion in 2021, adhering to NSPI and NPCC design criteria. Contingency testing focused on voltage and flow limits, with details in Section 3.2.2.
