Active Filtering Typical Case - Case 12
Oilfield Harmonic Treatment Program: Background of the project: The main load of the oil field is the mud pump and drilling equipment with speed control equipment. Since the speed regulating equipment is a non-linear load, it will inevitably produce severe voltage and current distortion, which often causes the logging recorder to record errors or data inaccuracy. Our company conducted on-site data testing for the 50DB and 70DB power supply systems of Daqing Oilfield, the 50DB and 70DB power supply systems of Changqing Oilfield in Shaanxi, and the 90DB power supply system of Xinjiang Karamay Oilfield. The data analysis shows that the cause of serious power quality problems is mud. During the working process of the pump and drilling equipment, the harmonic voltage generated affects the normal operation of the logging tool, so harmonic management must be carried out. Reconstruction plan: Through on-site power quality diagnosis, our company has proposed an active voltage quality controller (AVQR) that is independently developed and produced to solve the problems of harmonics, fluctuations, flicker, instantaneous interruption of the logging voltage of the logging instrument, and makes the logging instrument reliable. , the record is accurate.
