The Application And Design Of Cluster Technology On Automation Of Substation

Substation is the important part of electric transport system. Improve the safety of substation and the level of economy course; reduce the staffer of substation and self service, the automation of substation technology need more deeply research and development.At present the popular automation of substation host mostly elect the dual module hot spare architecture. The aim is fall the system risk of single server. The actual dual module hot spare architecture is specially cluster software, and be qualified the special server and disk Raid. It is high cost to the small substation, and much to the old substation reconstruct. It is high cost and difficult to maintenance. It need the station tech have the higher usability and lower cost. By deeply research the technology of cluster, carry out the dual module hot spare architecture on common PC server, and application in the small substation automation, it has great meaning.The design adopt the Microsoft Cluster tech to achieve the dual module hot spare architecture on the common PC server, and disk Raid, lower the cost.Adopt the double node cluster achieve that the system program auto transform to the another server when the system error. The host t of automation substation of system runs in gear. The communication of the host is impregnability. The whole system is not stagnating for the error.The report research and analysis the usability and estimate system of dual module hot spare architecture. According as the analysis carry the improvement to the dual module hot spare architecture, integrate the existing substation of automation put forward the project of dual module hot spare architecture by software, strengthen the heartbeat of cluster ,ensure the integrity and nicety when the server take over.
