Key technology and experimental verification of subsea equipment power supply by remote variable frequency drive in offshore oil and gas field

With the gradual deepening of my country’s deep-sea oil and gas field exploration strategy and the continuous development and application of sub-sea production technology, the sub-sea power supply system will become an important factor restricting the development and innovation of our country’s sub-sea production technology. By carrying out load mutation, motor startup, compressor simulation and other long-distance variable frequency power supply system tests, the test verification ability of the medium voltage high-power variable frequency drive power supply system is verified, which shows that the system can effectively simulate the application conditions and operating conditions of the actual project. Provide comprehensive technical support for the research of sub-sea power supply system.
