Compressor unit is the core equipment of long distance natural gas pipeline project, generator-driven compressor unit is preferred drive mode, has the advantages of stable operation, less faults, simple maintenance, low maintenance cost, high efficiency, energy saving and environmental-friendly. West-to-East Gas Pipeline Project, Shan Jing Gas Pipeline, China-Guizhou Gas Pipeline, China-Myanmar Gas Pipeline, Sichuan-east Gas pipeline, as well as the third line of West-to-East Gas Pipeline Project and China-Russia East Gas Pipeline under construction all adopt a large number of variable frequency generator-driven compressor unit.
Nancal NC HVVF series 20MW medium voltage AC drives have exclusive VSV (frequency control and reactive compensation) function, hence VFD can work in two operation modes of frequency conversion drive and power factor compensation, realizing one machine with two functions, avoiding reactive power penalty and maximizing investment income. The main loop diagram of the system as shown below:
