The Design and Implementation of Alarm Information Directly Transfer System in UHVDC Projects

Abstract:

Now dispatch centers needs to do a lot of work configuration and spend a lot of time to debug to communicate with substations. This is not only time-consuming but also error prone, so the alarm information needs to be directly sent. This paper presents the design and implementation of Alarm information directly transfers system, gives the system structure and software architecture of AIDT system used in UHVDC project; getting SOE based on distributed component Ice, realizing the protocol based on finite-state machine. And combined with the actual example, this paper provides a detailed explanation of the message. The program can be running on multiple operating systems including Debian Linux, KyLinux, HPUX and so on. Successful interoperability experiments proved that this system has good consistency, and running a long time in actual project proves the stability and reliability of the system. This system not only satisfies the need of UHVDC, but also has guiding significance on the research of AIDT system in UHVDC project.
