智能油井电参数测试仪的研究
|
摘要
随着能源消耗加大与开采量递减之间的矛盾日渐激化,国内各油田单位力争把节能降耗贯穿于油田生产经营的整个过程。在油井系统工作的过程中,抽油机的拖动电机起着核心作用,它的利用率的高低直接关系开采的成本和效益。油田野外生产作业,给油井生产管理带来很大困难,而目前所使用的主要手段仍然是通过人工测试来强化油井管理,局限性较大。针对这一现状,本课题以TMS3202812为核心芯片开发一套智能油井电参数测仪来解决这一问题。
本文引入了利用DSP技术测试电力参数的思想,采用同步锁相技术实现同步采样。本测试仪采用TI公司TMS320F2812作为核心处理器,利用电流、电压互感器测得到模拟电信号,通过ADS8364实现多通道的数模转换,由液晶显示屏显示出计算的电参数结果,并可以通过ISP1581芯片实现USB传输给PC。该系统具备3路电压、3路电流信号的同步采集能力。同时,本文就系统中使用的有关键算法进行了论述。使用整周期的采样序列均方根值来计算电压、电流有效值,使用整周波的同时采样的电压、电流采样做乘积,再取平均值的方法来计算有功功率。采用数字信号处理技术进行电力参数的测量,在提高测量精度、实时性和智能化、系统化水平方面都具有独特优势。
本系统的开发成功将进一步推进油井系统的自动化水平,更有利于油井系统管理人员正确分析油井系统效率,实现油井系统的节能降耗。
With the increasing intensification of contradictions between the increased energy consumption and reduced production, domestic oil fields strive to reduce the energy consumption throughout the whole process of the oil production. In the oil well system, the pumping unit motor drag plays a central role, and it affects the level of utilization of the costs and benefits of mining. Field production operation brings many problems to the oil wells production control. Manual testing is still the main measurement we use now to enhance oil wells production control. However, it has many limitations. According to the present situation, we design a set of intelligent tester of electrical parameters for the oil well, which used TMS3202812 as the core chip, to solve the problem.
This paper introduces the application of DSP testing of electrical parameters and genlock for synchronous sampling. Tester adopts TMS320F2812 produced by TI firm as the core processors, getting analog signals by current transformer and voltage transformer, achieving digital-to-analog conversion through the multi-channel by ADS8364, showing the results of the calculation of the electrical parameters by the LCD screen, and achieving that data sent from the tester to PC by ISP1581 of USB chip. It can simultaneously collect the Rd 3 voltage and Rd 3 current. Meanwhile, the key algorithms applied in this system are introduced: using the whole frequency sampling sequence to calculate the voltage RMS, current RMS; calculating the active power by the product of samplings of voltage and current and then the mean value. Adopting digital signal processing technology parameters in the measurement of the power has unique advantages in improving measurement accuracy, and real-time, intelligent, systematic level.
The success of this system will further advance the level of automation system of the oil wells, and help the system management staff improve the correct analysis of oil system efficiency and energy saving.
