Simulation Research Of Subsea Production Facilities Test Signal Calibration Device

With the continuous increasing demand of petroleum, countries in different world continue to strengthen the exploit of subsea oil and gas, which promote the development of the system of deep sea. The safety working situation of the subsea electrical control system can guarantee the whole system of the submarine production system, and which is the key device of the subsea oil and gas resource. And signal test calibration device provide the reliable dates for the whole subsea electrical control system, so the stability and reliability of the signal test calibration device is vital. Our country starts late in the subsea production electric control system, so we have far behind the developed countries. To change this awkward situation, we begin to study the signal test calibration device of subsea electrical control system. It has a big significance for our country in subsea oil and gas resource exploration.Firstly, this article illustrates the working theory and control process of subsea separator and oil extraction tree, and states a overall plan of the signal test calibration device.Secondly,illustrates the software constitution of signal test calibration device on the basis of the signal test calibration device's overall plan, finished the Cutting and transplantation? the building of software platform?Hardware drivers?compile of the users to the signal test calibration device's control system. What is more, it has finished the control process in the basis of the model building to the subsea separator and the analysis to the oil extraction tree.Once more, it has finished the whole design of the signal test calibration device, which contains the building of hardware platform and the design to the external shell. As well as the ANSYS, which do some good to the job of subsea.At last,add LDPC codes in the communication channel,achieve the wrong codes rate to 10-4 by the control of codes rate. It had finished the working process simulation of subsea separator and oil extraction, and the verify of the signal test calibration device.
