变电站站控层服务协议CMS的应用研究

Research on a CMS protocol for the substation control layer

为了实现变电站站控层通信核心技术MMS(制造报文规范)的国产替代,国家电网公司制定了变电站二次系统CMS(通信报文规范),但未给出具体应用实现方案。因此,为推动CMS协议的应用和变电站核心技术的自主可控研究,提出一种在自主可控新一代嵌入式保护装置上实现CMS协议应用的解决方案,阐述了方案具体的程序实现方法,包括编解码实现、通信结构实现、CMS与MMS兼容性应用以及通信安全等,通过服务一致性测试和代码健壮性测试验证了方案的可行性。方案已在自主可控新一代产品平台中得到应用。

To achieve a domestically developed alternative to the manufacturing message specification(MMS) as the core communication technology for the substation control layer,the State Grid Corporation of China has established the communication message specification(CMS) for secondary systems in substations.However,the specific application implementation plan has not yet been provided.Therefore,to promote the application of the CMS protocol and advance research on the independent and controllable core technology of substations,a solution is proposed to implement the application of the CMS protocol on a new generation of independent and controllable embedded protection devices.The solution outlines specific implementation methods,including encoding and decoding,communication structure,compatibility application of CMS and MMS,as well as communication security.The feasibility of the solution has been verified through service consistency testing and code robustness testing.The solution has been applied in the new generation of independent and controllable product platforms.
