基于IEC 61850标准的ECMS技术在海门电厂的应用研究与实现

摘要

结合实际工程实践提出了一种基于IEC 61850标准实现数字化电厂电气监控管理系统的解决方案.详细阐明了该方案的相关特点和系统架构,尤其强调了其中数字化过程层技术的应用特点,并以电厂6 kV数字式母线差动保护的经济型解决方案为实例详细说明该解决方案的实现方法.该方案最终在华能海门电厂(6×1000 MW)机组的ECMS工程上的得到应用,证明了所提基于IEC 61850标准的数字化电厂电气监控管理系统解决方案的有效性和可行性.%Combining the practical engineering, we propose a scheme to establish the electrical control and management system (ECMS) for digital power plant based on IEC 61850 standard. Its characteristics and system framework especially the advantages of the digital process level technology are elaborated. Then we take the case of an economical solution to 6 kV busbar differential protection to illustrate the implementation of the scheme. Finally, we apply the scheme in Huaneng Haimen Power Plant (6*1000MW) ECMS project successfully, and prove its validity and feasibility.
