Research on power supply design method of well control and lift control system

针对带压装置操作程序繁琐,用液压与自动控制相结合的方式形成井控设备与夹持装置的逻辑控制,实现了操作流程自动化。但有关供电设计部分保护功能简单、易间断、可靠性较低。首先介绍了液压与自动控制相结合的井控与举升控制系统设计原理,而后具体剖析了已有电源模块中双AC/DC转换器的冷备用、热备用衔接模式各自存在的问题,并提出了一种双AC/DC转换器供电系统设计方案。研究结果表明,双AC/DC转换器能够增强供电模块的可靠性,有效地解决了直流电源在供电中的可持续问题。

In view of the cumbersome operation procedure of the pressure device,the logic control of the well control equipment and the clamping device is formed by the combination of hydraulic pressure and automatic control,and the operation flow is automated.However,the protection function of the power supply design is simple,easy to break,and low in reliability.This paper first introduces the design principle of well control and lift control system combining hydraulic and automatic control,and then analyzes the problems of cold backup and hot backup connection modes of dual AC/DC converters in existing power modules.A design scheme of the dual AC/DC converter power supply system is proposed.The research results show that the dual AC/DC converter can enhance the reliability of the power supply module and better solve the problem of continuous power supply of the DC power supply.
