Abstract

Petroleum and chemical refining, along with all other process industries, utilizes many electric motors to meet power demands. This article discusses results of an assessment survey of installed motors and drives performed by Lawrence Berkeley National Laboratory (LBNL) and funded by the U.S. Department of Energy (DOE) [1]. A key finding was that there are energy savings available with the addition of adjustable speed drives (ASDs). The National Electrical Manufacturers Association (NEMA) is collaborating with the Northwest Energy Efficiency Alliance (NEEA) and Cadeo Group to develop a prescriptive process to allow for rebates for power drive systems (PDSs) consisting of a premium efficiency electric motor and an ASD. Most efficiency standards, such as NEMA MG 1 [2] or International Electrotechnical Commission (IEC) 60034-30-1 [4], today focus on the efficiency of the components, with or without an ASD, rather than focusing on energy savings through optimized process management NEMA MG 10011 [3]. Organizations are now looking at the combined energy use of the PDS, especially on variable torque loads, such as pumps, fans, and compressors that are commonplace in process industries. This is a paradigm change from component efficiency to energy savings through a PDS system.

能源部电机和驱动评估确定了电力驱动系统的节能:一个范例的改变

石油和化学炼制，以及所有其他加工工业，利用许多电动机来满足电力需求。本文讨论了由美国能源部(DOE)资助的劳伦斯伯克利国家实验室(LBNL)对已安装的电机和驱动器进行的评估调查的结果。一个重要的发现是，增加可调速驱动器(asd)可以节省能源。美国国家电气制造商协会(NEMA)正在与西北能源效率联盟(NEEA)和Cadeo集团合作，制定一项规定程序，允许由高效电动机和ASD组成的动力驱动系统(pds)获得回扣。大多数效率标准，如NEMA MG 1[2]或国际电工委员会(IEC) 60034-30-1[2]，今天都侧重于组件的效率，无论是否有ASD，而不是通过优化过程管理来节省能源。组织现在正在关注PDS的综合能源使用，特别是在可变扭矩负载上，例如泵，风扇和压缩机，这些在过程工业中很常见。这是一个范例的改变，从组件效率到通过PDS系统节约能源。
