The appearance of frequency converter has brought a revolution to the way of AC speed regulation. With the continuous improvement and development of frequency conversion technology in recent ten years. The performance of variable frequency speed regulation is becoming more and more perfect. It has been widely used in different fields by engineers and technicians in different disciplines and industries. It brings considerable economic benefits for enterprises and promotes the automation process of industrial production.

Moreover, it has the advantages of simple structure, wide speed regulation range, high speed regulation precision, convenient installation and debugging, perfect protection function, stable and reliable operation, and remarkable energy-saving effect, which has become the latest trend of AC motor speed regulation. Double circuit scheme of common AC bus

As the electric submersible pump is used outdoors (on the sea), its working environment and the working environment of its power distribution equipment are relatively bad; and the oil production operation requires high reliability of the oil production equipment, so when using the frequency conversion system sharing AC bus, the power frequency standby system (frequency conversion power frequency double loop system) should be added or the frequency conversion system should be added on the basis of the original power frequency system In this way, the power frequency system and the frequency conversion system can be used as standby for each other, even in the case of frequency conversion system failure or maintenance, the impact on oil production operation is not big, so as to improve the safety and reliability of oil production equipment (system).
