【Abstract】 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.更多还原
