This week, Clean Line Energy and HVDC engineering consultants, TransGrid Solutions (TGS), took an important step in the design of the Plains & Eastern Clean Line with the task of measuring the background harmonic voltages that exist in the electric grid at the points where the Plains & Eastern Clean Line HVDC Project will interconnect.

Power quality meters were installed at TVA’s 500kV Shelby substation near Memphis, Tennessee and SPS’s 345kV Hitchland substation near Guymon, Oklahoma, where the meters will continuously sample bus voltages at these stations for analysis by TransGrid Solutions. The knowledge gained from taking these measurements will help fine tune the HVDC design and ensure properly rated equipment. Clean Line and TGS will return to the field in two weeks to connect a power quality meter in Arkansas at Entergy’s 500kV Pleasant Hill substation to accommodate the design of a proposed nearby converter station, which Plains & Eastern refers to as its “midpoint converter”. Clean Line is excited to continue field work in order to advance the technical design of the Plains & Eastern Clean Line Project.
