基于VPN实现汽轮机组远程维护和诊断

针对电厂的汽轮机组及其监控系统，通过综合采用虚拟专用网(VPN)的隧道和加密等安全技术，结合远程控制软件，实现安全地经Internet对其进行及时的远程维护和诊断，既保证了电厂的数据安全，又节省了网络和通信费用，还具有良好的通用性。文中结合项目示例，介绍该方法的结构和工作原理，以及采用的VPN技术和软硬件设备。该方法应用效果良好。

IMPLEMENTATION OF REMOTE MAINTENANCE AND DIAGNOSIS FOR TURBO GENERATOR SET BASED ON VPN

This paper presents a new method of safely implementing timely remote maintenance and diagnosis through the Internet for the turbo generating sets and their monitoring system in a power plant. The method is based on VPN security technology (tunnel, encryption, etc.) aided by the remote control software. Not only can it ensure the data security of power plant and reduce the cost of network and communication, but also it has good universality. In this paper, the principle and the framework of the method are introduced. The VPN technology and equipment are also discussed. The method has proved feasible and effective in practice.
