摘要
随着微机技术的不断发展 ,以 L inux为代表的自由软件越来越多地应用于包括工业控制在内的广泛领域。作者对把自由软件应用到调度自动化系统中这一课题进行了可行性研究。通过将 EMS/ DTS从传统 Unix工作站平台移植到PC/ L inux平台 ,并用实际电网数据进行测试 ,得到的结果是 :PC/ L inux平台有如下优点 :其计算结果与 U nix工作站平台一致 ,同样配置的 PC/ L inux平台运行速度比 Unix工作站高 3倍 ,而后者的系统负荷大约只为前者的一半 ;PC/L inux平台具有丰富而强大的应用软件 ,开发效率大为提高 ;其缺点是软件的汉化程度不够。在此平台上开发的新一代调度自动化系统已经移植到传统 Unix工作站平台并应用到了多个实际电网中。在此还进一步探讨了将嵌入式 L inux系统应用于 SCADA系统的广阔前景。
Along with the development of microcomputer techniques, free software which can be represented by LINUX has been applied to various domains including industrial control. A feasibility research on the application of free software to dispatch automation systems is performed in this paper. Based on data from actual power networks,the tests of transplanting EMS/DTS systems from the traditional workstation platform of UNIX to the PC platform of LINUX were successfully performed and following results were obtained: the calculation results of both platforms are identical, but the running speed of the PC/LINUX platform is increased 300% than UNIX platform and the system load of the former is approximately half of the latter with same configuration; because PC/LINUX platform possesses plentiful and powerful application software, its development efficiency is remarkably improved; however, the defect of PC/LINUX platform is that its Chinese characterization degree is not hinght enough. A new generation of dispatch automation systems developed on this platform has been transplanted to traditional workstation platform of UNIX and is applied to many practical power networks. In this paper the prospect of applying embedded LINUX system to SCADA systems is discussed.The research and application prove that it is feasible to apply free software to dispatch automation systems.
