IEC 61850应用剖析及其发展探讨

Discussion on applications of IEC 61850 and its development

作为智能变电站的数字化基础,IEC 61850在促进变电站技术进步的同时,本身在应用中也反映出若干设计上的缺陷。在深入剖析IEC 61850标准现状和应用实践情况的基础上,反思了其成败得失。针对智能变电站的部分发展需求,不再完全局限于标准约束,提出了IEC 61850补充性框架设计思路。提出IEC 61850的变电站设备模型及其相关的服务模型可以简化,变电站配置描述语言需要摆脱低效、庞大的弱点,需要利用特定通信服务映射机制设计新的高效通信协议栈,并增强与调度端的无缝通信能力。最后利用CIM/E语言、电力通用服务协议等成果对IEC 61850进行了补充性的改进设计示例。

As a digital basis of smart substation, IEC 61850 has promoted the advancements of the substation technologies. But at the same time, several design defects are also reflected in the applications. Based on in-depth analysis of the status and practical applications of IEC 61850, its advantages and defects are summed up. According to some of the requirements for smart substation development, a complementary architecture for IEC 61850 is put forward, which is no longer confined to the current standard constraints. It is pointed out that, the intelligent electronic device （IED） models of IEC 61850 and its related service models may be simplified, the Substation Configuration Description Language （SCL） needs to get rid of the weakness of low efficiency and hugeness, a new efficient communication protocol stack needs to be designed by using the Specific Communication Service Mapping （SCSM） mechanism, and the seamless communication ability with dispatching ends need to be strengthened. Finally, an improvement design as supplementary protocols for IEC 61850 standard is put forward by using the CIM/E language and the general service protocol for electric power systems.
