[Abstract]:With the continuous renewal of power electronic devices, the performance of purifying and stabilizing power supply is improving step by step. It has been widely used in many important occasions, such as hospitals, oil exploitation and so on. During the 12th Five-Year Plan period, the state took deep-sea oil and gas exploitation as an important strategy. Therefore, under the guidance of relevant policies, the research of underwater production joint test system and underwater production control system has been on the fast track. As an important part of underwater production test system, digital AC purifying and stabilizing power supply can realize the function of voltage stabilization and voltage regulation, guarantee the smooth running of production test, improve the working reliability of underwater controller and reduce unnecessary loss. Based on the traditional design method, this paper uses compound control strategy and intelligent operation mode to effectively improve the working efficiency of power supply system, realize on-line monitoring of parameters and system fault diagnosis. The main work and innovations of this thesis are as follows: (1) through comparative analysis, the single-phase full-bridge inverter model is established, the transfer function of the inverter model is derived, and the dynamic and static performance of the system is improved by using digital PID and non-beat composite control mode. The digital PID algorithm is used to improve the control precision of the voltage outer loop, and the output voltage error is reduced, and the beat free algorithm is used to improve the dynamic performance of the current inner loop. (2) the modular design idea is adopted in the hardware development of the power system. Part of the circuit gives the schematic design process, through the parameter calculation and simulation analysis, continuously optimize the hardware circuit parameters, improve the system performance, the system software design mainly around the SPWM algorithm, serial communication, data acquisition and other modules, The modular programming method makes the program management more efficient. In order to realize local measurement and control of power supply and remote monitoring, the system designs two working modes: local operation, remote operation, and this power supply is applied in the joint test system. In order to ensure the reliable operation of the power supply, the design of the cabinet takes full account of the requirements of preventing moisture and salt mist. (3) the debugging of the steady voltage power supply is divided into module debugging and the whole machine debugging, after debugging and processing, In order to verify the power supply index, make the system test plan according to the relevant standards, use the power network simulator, anti-insular load device and other equipment, simulate the working state of the power supply, and analyze the test results, In order to judge the working state of the system, the improvement scheme is given, and the design of the power supply system takes into account the influence of EMC, and the anti-interference measures are given. The digital power supply realizes multi-function operation and has the purifying and stabilizing function of traditional power supply. With the continuous development of deep-sea oil production and underwater production joint test system in China, its application will be more and more extensive.
