针对配电网调度监控图形界面的部署和图元处理效率不高的问题,将矢量图元嵌入富网络组件容器的应用框架中,提出一种富网络架构的调度界面快速GAS监控新模式。基于异步分层回调框架,综合运用GWT交叉编译、JSNI本地化接口和支持多事件线程的并发回调机制,给出了调度图形界面关键代码的编译处理流程,实现了调度监控界面免部署和矢量图元的局部刷新。以10 k V配电网调度自动化系统为算例,对调度监控界面进行了渗入测试和并发测试,结果表明:异步回调主机可获得小于20%的处理器使用率和7%的内存占有率,SVG界面的多事件线程局部刷新和异步回调机制,使监控画面平均刷新延时降为百毫秒级,验证了GAS模式对提高界面响应能力的有效性。
In order to solve problem of graphic interface deployment and low efficiency of graphic element processing in distribution network dispatch supervisory system, a fast GAS dispatch interface callback model based on rich internet architecture is put forward by embedding vector elements into component containers and rich internet application framework. Based on layered asynchronous callback framework, a compilation process of key codes for scheduling graphic interface is given, and free deployment and partial refresh are implemented by coordinating GWT cross compiling technology, JSNI native interface and multiple event threads supported by asynchronous callback mechanism. Taking a 10kV distribution network dispatch monitoring system as example, results of penetration and concurrent test show that host of asynchronous callbacks gets less than 20 percent of processor and 7 percent of memory share, and average delay of monitor screens can be reduced to level of hundreds milliseconds by using multi-threads partial refresh. Monitoring efficiency of GAS model is verified.
