负载均衡和虚拟集群技术在智能电网调度技术支持系统中的应用

Application of Load Balancing and Virtual Cluster Technology in Smart Grid Scheduling Technology Support System

利用先进的负载均衡和虚拟集群技术是改善智能电网调度技术支持系统中电网实时调度业务的有效手段,通过阐述某地调(简称地调)综合智能告警窗口的挂住现象,分析并发现实时库高负载是产生上述现象的主要原因。在实时库高负载的情况下,将服务器运行的实验数据与分别采用负载均衡和虚拟集群负载均衡两种技术的实验数据进行对比,验证了结合虚拟集群和负载均衡两大技术是改善实时库高负载的有效方法。

It is an effective method to improve real-time scheduling service in Smart Grid Scheduling technology Support System by applying advanced virtual cluster and load balancing technologies. Analysis on the suspension phenomenon in the integrated intelligent alarm window which happened to the dispatching system of a certain district is given, and the main cause for the high loading of real-time database to generate the above phenomenon is figured out. Under the condition of high loading of real-time database, experimental data of the server are compared to that of the server after using load balancing technology and virtual cluster load balancing technology. The result shows that the consolidation of virtual cluster technology and load balancing technology is an effective method to improve the problem of high loading of real-time database.
