    Introduction - Variable Speed Drives (Controllers) in the Artificial Lift Electric Submersible Pump industry: 导言-变速驱动器(控制器) ,在人工举升电动潜油泵行业:

    Adding a variable speed drive (VSD) to an ESP system offers several advantages.加入一种变速传动(室间隔缺损) ,以一个ESP系统提供了几种优势。 VSD’s belong to a group of equipment also referred to as adjustable speed drives (ASD), variable frequency drives (VFD) or adjustable frequency drives (AFD).室间隔缺损的同属于一个集团的设备也被称为可调速驱动器( ASD )的,变频驱动器( VFD的)或可调频率驱动器(渔农处) 。 The operating speed of a motor connected to a VSD is varied by changing the frequency of the motor supply voltage.系统运行速度的马达连接着一个室间隔缺损是多种多样,通过改变频率的电动机供电电压。 This allows continuous speed control.这使得连续速度控制。 ESP systems are often designed to handle peak loads that have a safety factor.电除尘系统的初衷往往是为了应付高峰负荷有一个安全因子。 This often leads to energy inefficiency in systems that operate for extended periods at reduced load.这往往导致能源效率低,在系统运行的很长时期,在降低负荷。 The ability to adjust motor speed enables closer matching of motor output to load and often results in energy savings.能调节电机转速,使紧密的配套电动机输出负荷,往往结果在节约能源的方法。


    Does your operation require certification such as UL-508, IEEE 519, EMC Directive, IP, & CE for onsite electrical equipment like VSD's?请问你的运作有需要的认证,如经UL 508 ,兼容IEEE 519 ,电磁兼容指令,知识产权,与行政长官上门电气设备如室间隔缺损的?

    Learn how to ask the right questions and uncover any vendor abnormalities in their certification process, to understand if your ESP equipment supplier is really certified for the equipment they are supplying you.学习如何提出正确的问题,并发现有任何异常的厂商在其认证过程,要了解如果你的电除尘器设备供应商, 实在是认证设备,他们提供您。

    Safety is #1.安全是编号1 。 Don't allow anything but certified equipment on your jobsite.不准许什么,但认证的设备在您jobsite 。

    Example - according to EMC Directive (89/336/EEC) article 10 part 1, the manufacturer is responsible for attaching the CE mark to each unit.例如-根据电磁兼容指令( 8 9/336/eec)第1 0条第1部分,制造商则负责附加C E标志,以各单位。 According to part 2 the manufacturer is responsible for writing and updating the Technical Construction File (TCF), if the TCF route is used.根据第2部分厂商则负责撰写和更新技术工程档案(万亿立方英尺) ,如果无氯航线使用。

    How Does a VSD Work?如何确定某个VSD的工作吗?

    Applying a VSD to a specific ESP application is no mystery when you understand the requirements of the load.运用室间隔缺损,以一个具体的电除尘器的应用并不神秘,当你了解有关规定的负载。 Simply put, the VSD must have ample current capability for the motor so that the motor can produce the required torque for the load.简而言之,室间隔缺损,必须有足够的电流处理能力,为汽车,使汽车能产生所需的转矩负载。 You must remember that torque is independent of motor speed and that load horsepower increases linearly with rpm.你必须记住,扭矩是独立的电机转速和负荷马力线性增加,与每分钟转速。

    A thorough understanding of how to match the VSD to the ESP driven load is the key to a successful application.彻底了解如何配合室间隔缺损,以就业带动负载是最关键的一个成功的应用。

    When applied properly, the variable Speed drive (VSD) is the most effective motor controller in the industry today.正确应用时,可变速驱动器(室间隔缺损) ,是最有效的马达控制器在业界今天。 Modern VSD’s are affordable, reliable and have flexibility of control.现代室间隔缺损的是负担得起,可靠和有弹性的管制。

    Electrical power is frequently transmitted to subterranean locations within boreholes to power downhole equipment, such as electrical submersible pumps (ESPs).电力是经常转发给地下位置钻孔,以电力井下设备,如电动潜油泵( esps ) 。 Normally three phase electrical power is transmitted from the surface over cables running between the well casing and the production tubing.通常三相电力传送从地表以上电缆运行之间的套管和生产油管。 In some downhole applications, high voltage electrical power is required.在一些井下应用,高压电力需要。 For example, electrical motors for ESPs may require voltages of 1,000 to 5,000 volts at the surface.例如,电动机为esps可能需要电压为1000年至5000年伏特,在表面上。 However, electrical drives capable of providing output voltages at the required level may not be available, or may not be economical even when available.不过,电驱动器,能够提供输出电压在规定的水平可能不存在,或可能不符合经济原则的时候,甚至可用。 When lower output voltage drives are employed in such situations, typically step-up transformers at the output of the drive are utilized to boost the voltage of power transmitted downhole.当低输出电压驱动器是受雇于在这种情况下,通常步升变压器的输出驱动器,是用来提高电压的功率转发了井下。

    Effects of Power Quality影响电能质量

    Financial consequence : when voltage sags, productivity lags.金融后果:当电压骤降,生产力落后。

    The characteristics of the utility power supply can have a detrimental effect on VSD reliability.特点公用事业的电力供应,才能有不利影响室间隔缺损的可靠性。

    Harmonics produced by the VSD can have an effect on the electrical distribution and the utility system.谐波所产生的室间隔缺损,可以有一个作用,对配电系统和公用工程系统。

    The characteristics of the current & voltage produced by the VSD Inverter can cause motor problems.的特点,当前的电压及所产生的室间隔缺损逆变器可导致电动机的问题。

    Poor power quality as it affects VSD reliability:穷人的电能质量,因为它影响到室间隔缺损的可靠性:
    •Transient Overvoltages •暂态过电压
    •Longer term high voltage •较长期高压
    •Long term low voltage •长期低电压
    •Harmonic and current distortion •谐波电流失真

    Eliminating harmonics from your facility power system is key.消除谐波从你的工厂电力系统是关键。 A special section of the ESPDrive.com message board is dedicated to power quality.专门章节的espdrive.com留言板致力于电能质量。 Click here.点击这里。

    Step-up transformers add to the expense of the system, however, and add additional sources of failure or disturbance to the electrical system.步升变压器放入牺牲系统的,不过,新增的来源衰竭或骚扰电气系统。

    Manufacturers typically cite the following benefits in the use of a VSD:制造商通常会举出以下好处,在使用一种室间隔缺损:

    •The most important is energy savings. •最重要的是节约能源的方法。
    •Accurate control and flexibility of the pump system selected •精确控制和灵活的热泵系统选定
