Liquefied natural gas peak shaving facilities utilize large horsepower motors to drive refrigeration compressors needed for the liquefaction process. Utilities impose strict voltage dip requirements making an evaluation of various motor starting methods imperative. The large motor starting studies must be evaluated while also factoring in equipment and controls complexity and overall project capital costs. This case study will evaluate several motor starting methods, comparing technical performance and cost considerations, identifying the best method for the project requirements and reviewing the field measurements during operation confirming acceptable performance of the installed method.
