摘要
近年来,电驱离心压缩机组在天然气管道压气站中被大量采用,国产电驱机组虽然起步较晚,但发展较快。回顾了国产电驱离心压缩机组在天然气管道的应用现状及发展概况,系统归纳了机组主要单元的组合方式、成套方式、电动机、变频调速装置、控制系统的主要技术特点。通过运行数据分析、典型故障分析及与进口机组对比分析等方法,归纳总结了国产电驱机组相对进口压缩机组的优势与不足,并在设计、运行、管理及售后方面提出建议。从20 MW以上国产电驱机组研制、国产电驱机组推广、变频高速异步电动机应用、集成式压缩机的研制以及磁浮轴承在国产分体式电驱机组上的研制与应用等方面进行了展望,认为国产电驱机组必将成为未来中国天然气管道输送的核心动力装备,也更加安全、环保、可靠、经济。
Motor-driven centrifugal compressor unit has been widely installed in the compressor station of natural gas pipeline in recent years. Motor-driven compressor unit industry of China starts late but develops fast. Here, the development and application of domestic motor-driven centrifugal compressor unit in natural gas pipeline was reviewed, and the main technical characteristics of compressor unit were described systematically, including combination mode of the main units, complete mode, electric motor, variable-frequency speed regulation device and control system. Through operation data analysis, typical fault analysis and comparison with imported unit, the advantages and disadvantages of the domestic motordriven compressor unit were summarized, and suggestions were put forward in terms of design, operation, management and after-sales service. Moreover, prospect was presented from the prospective of development of domestic motor-driven compressor unit above 20 MW, promotion of domestic motor-driven compressor unit, application of high speed variablefrequency asynchronous motors, development of integrated compressor, development of magnetic bearing and its application in domestic split type compressor unit. Generally, it is concluded that the domestic motor-driven compressor unit will become the core power equipment of China’s gas pipeline in future, and it will be safer, more environment-friendly, more reliable and more economic.
