摘　　要：当前配电网保护终端平台仍采用封闭架构,高昂的平台操作系统授权价格以及封闭的开发环境,抑制了配电网保护控制业务海量的需求。针对开发者代码隔离诉求和网络保护性能约束,提出了一种基于Linux实时操作系统的配电网智能保护控制终端新平台。新平台拥有Linux开源、代码隔离、业务实时性支撑等特点。首先基于普通Linux操作系统嵌入实时补丁、设计实时进程调度和应用内存共享机制,以构造新平台基础。然后,设计了数据实时处理模块和保护业务服务模块,以服务配电网保护控制应用。最后,通过搭建软件测试环境,验证了新平台进程实时处理能力、重采样抖动控制能力。通过搭建RTDS实时数字仿真系统,验证了新平台下的网络保护应用性能。测试均取得了预期效果,验证了新平台设计的工程适应性。The current distribution network protection terminal platform still adopts a closed architecture,and incurs a high licensing price of the platform operating system as well as a closed development environment.This all inhibits the massive demand for distribution network protection and control services.Considering developers'code isolation requirements and network protection performance constraints,a new platform for distribution network intelligent protection and control terminal based on the Linux real-time operating system is proposed.The new platform has the characteristics of Linux open source,macro kernel,real-time business guarantee and so on.First,this paper embeds real-time patches,designs real-time process scheduling and applies a memory sharing mechanism to a common Linux operating system to construct a new platform foundation.Then,the sampling data real-time processing module and the protection business service module are designed to serve the distribution network protection control application.Finally,by building a software test environment,the real-time processing capability and resampling jitter control capability of the new platform process are verified;by building an RTDS real-time digital simulation system,the network protection application performance under the new platform is verified.The tests all achieve the expected results,which verifies the engineering adaptability of the new platform design.
