摘　　要：随着特高压电网建设的不断推进和智能电网发展方向的确立，电网对稳定控制装置在数据分析处理能力和通信能力上的要求不断提高，而目前电网稳定控制装置中普遍采用的“中断＋主循环”的嵌入式软件设计模式将难以满足日益复杂的功能要求。该文探讨了稳定控制装置对软件设计的技术要求，指出了目前稳定控制装置软件设计模式中存在的不足，并分析了将VxWorks、QNX、RT—Linux等主流嵌入式实时操作系统应用于稳定控制装置设计的可行性，并对任务调度实现进行了分析研究。With the continuous construction of UHV grid and the establishment of smart grid development, the requirements to stability control device in data analysis, processing and communications capability is rising. The embedded software design patterns of ＂interrupt ＋ main loop＂ commonly used by stability control device will be difficnlt to meet the increasingly complex functional requirements. This paper discusses the technical requirements of stability control device for software design, points out the current flaws in software design patterns of stability control device, and analyses the feasibility of using embedded real-time operating system like VxWorks,QNX and RT-Linux in design of stability control device, researches the design of task scheduling with these real-time operating systems.
