As a critical downhole conveying equipment, the ESP variable frequency drive system faces three major challenges: long-cable transmission, choke signal interference, and harsh on-site operating environments. Nancal Electric's medium voltage drives, based on cell series multi-level topology, with long-cable adaptive control as the core and choke system compatibility as a distinctive feature, effectively address industry pain points through deep integration of hardware optimization and software algorithms.
This medium voltage drive has been in stable operation on-site for over three years and has withstood multiple grid voltage sags of varying severity.The power cell fast automatic bypass design and the Low Voltage Ride Through (LVRT) capability of Nancal Electric's medium voltage drives address internal cell failures and external grid voltage sags, respectively, effectively preventing unplanned shutdowns caused by such issues.
Storage is an energy infrastructure integrating the functions of seasonal peak regulation, emergency gas supply and national energy strategic reserve. As a key equipment supplier of compressor units, Nancal Electric has excellent on-site service technology and fast response, which has been highly praised by Petrochina Southwest Oil and gas Field Huangcaoxia Gas Storage Construction Project Department and Sichuan Huacheng Supervision Company.
