Abstract
The scope of this study is to determine the short term overload capability of Cable No. 116 in the event of the loss of one pole of the dc transmission system. Such a loss would result in the loss of 250 MW of transmitted power. This exceeds the spinning reserve capability of the Hawaiian Electric Company on Oahu. The maximum allowable first contingency power loss which can be accomodated by the available spinning reserve while maintaining the integrity of the system is 125 MW. The loss of one pole of the dc system would therefore require an increase of 50 percent in the transmitted power on the remaining pole for a period of time up to 4 hours. The surviving pole conductor during this period must therefore carry 150 percent of rated power, i.e. 375 MW corresponding to 1250 amps. The findings are included in this report.
