智能变电站虚拟二次回路监视方案设计及应用

Design and Application of Virtual Secondary Loop Monitoring Scheme for Smart Substation

当下能源产业一直处于长期稳定运行以及发展阶段,极大地促进了我国经济的发展和人民生活质量的提高。智能变电站已经成为目前主要用于连接发电和输出用电的枢纽,也成为了我国智能电网构建的基础设施,是保证我国电网安全平稳运行的关键环节。对于目前智能变电站的研究上,国内外已经有比较基础的技术支持,在此的基础上要设计智能变电站虚拟二次回路监视方案并进行深入研究,进而推动智能变电站的电网创建,使其发挥出重要作用。但是智能变电站在目前的信息化模型建设中还存在一定的问题,也就是没有相应的二次回路监视系统,这种系统可以全面地改善变电站在监视和运行维修方面的反馈与诊断。而且传统电缆已经被技术更为高级的光纤所代替,所以现如今可以选择通过网络通信更好地实现设备间的信息传递,在智能信息化的变电站设备运行过程中,出现的问题也可以更快得到反馈,同时及时通知人员维修。这在一定的限度上为变电站节约了时间成本和人力成本,提高了维修效率,进而促进智能变电站的工作效率。

At present,the energy industry has been in a long-term stable operation and development stage,which has greatly promoted the development of China’s economy and the improvement of people’s quality of life.Smart substation has become the hub mainly used to connect power generation and power output,and has also become the infrastructure of China’s smart grid construction,which is a key link to ensure the safe and stable operation of China’s power grid.For the current smart substation research,there has been relatively basic technical support at home and abroad,on this basis to design smart substation virtual secondary loop monitoring scheme and in-depth research,and then promote the establishment of smart substation power grid,make it play an important role.However,there are still some problems in the current information model construction of smart substation,that is,there is no corresponding secondary loop monitoring system,which can comprehensively improve the feedback and diagnosis of substation in monitoring and operation and maintenance.And the traditional cable has been replaced by more advanced technology of optical fiber,so now you can choose to better realize the transmission of information between equipment through network communication,in the process of intelligent and informationized substation equipment operation,problems can also get feedback faster,at the same time timely inform personnel maintenance.This saves the time cost and labor cost for the substation to a certain extent,improves the maintenance efficiency,and then promotes the work efficiency of the intelligent substation.
