“…In recent years, many pipeline systems have introduced new materials or improved equipment to reduce pipeline energy consumption. If there is the use of drag reducers to increase the oil output and improve the efficiency (Guan et al, 2008), if there is the use of variable frequency speed regulation, in 2015, Hoevenaars et al used harmonics to adjust the variable speed drive to make the generator more operability and transformational., Achieved the purpose of saving energy and fuel (Hoevenaars et al, 2015). In 2018, Liu et al used variable frequency speed regulation technology to reduce the load of the centrifugal pump by 20%-50% through speed regulation, effectively match the output power of the motor and the pipeline flow, and reduce energy consumption (Liu et al, 2018).…”
