A major portion of Manitoba Hydro's generation is located in the North on the Nelson River. The lower Nelson River generation is brought into the load centre in Southern Manitoba through an HVDC transmission system consisting of two bipoles, the first rated at 1680 MW at the rectifier and the second at 2000 MW. This paper presents the methodology used in arriving at the optimum Bipole 3 size using a reliability cost-benefit analysis. The analysis considers the forced outages of the generation and transmission systems using system outage statistics. The generator and valve group maintenance and the reduction in capability of thyristor valve groups during the summer season were also incorporated in the analysis. The load model used in the study was based on system data for the period 1980-1984. The criterion used in choosing the Bipole 3 size is to optimize the present worth value of the annual energy curtailment due to the HVDC system forced outages and the incremental installation cost of the transmission as the capacity of Bipole 3 is increased. The optimum Bipole 3 size based on the study is 2200 MW. This value is significantly lower than that based on a pole spare criterion used in the earlier development of the HVDC system. Finally, the need for validation of the outage data in evaluating future HVDC projects and the need for data collection and classification is indicated.
