目前在天然气输送系统中使用的离心式压缩机有许多喘振控制方案。基本上，这些方案由一组检测设备组成，这些设备要么预测浪涌，要么在其开始时检测它，以及一组控制设备，以防止浪涌的发生。进行专利检索是为了评估过去20年技术发展的水平和方向，并确定未来研发活动的重点。此外，本文还介绍了电涌控制、电涌检测和电涌抑制三个方面的技术现状。从在线数据库中获得的专利数据表明，大多数重点都放在浪涌控制上，而不是检测和控制上，目前浪涌控制的趋势可能会继续朝着基本或传统浪涌控制策略的渐进改进方向发展。各种喘振抑制技术可以分为两类：(i)那些专注于更好的压缩机内部设计的技术，以及（ii）其他试图通过外部和操作手段抑制喘振的技术。
There are a number of surge control schemes in current use for centrifugal compressors employed in natural gas transmission systems. Basically, these schemes consist of a set of detection devices that either anticipate surge or detect it at its inception, and a set of control devices that act to prevent surge from occurring. A patent search was conducted in an attempt to assess the level and direction of technology development over the last 20 years and to define the focus for future R&D activities. In addition, the paper presents the current state of technology in three areas: surge control, surge detection, and surge suppression. Patent data obtained from on-line databases showed that most of the emphasis has been on surge control rather than on detection and control and that the current trend in surge control will likely continue toward incremental improvement of a basic or conventional surge control strategy. Various surge suppression techniques can be grouped in two categories: (i) those that are focused on better compressor interior design, and (ii) others that attempt to suppress surge by external and operational means.
