摘要
数字孪生利用智能传感、虚拟现实、人工智能等技术,可以实现对物理实体的实时、全生命周期的监测与建模。数字孪生电网建设将数字孪生技术与电力系统结合,是推动我国电力系统转型的重要方向。文章介绍了数字孪生的基本内容,基于现有数字孪生电网的技术框架,分析各层次中存在的安全问题,并提出一系列防护措施,为数字孪生电网的建设提供技术和管理方法的参考。
Digital twin based on technologies such as intelligent sense,virtual reality and artificial intelligence can realize the real-time,life cycle monitoring and modeling of the physical entities.The construction of digital twin of power systems(PSDT)combines digital twin and power system,which is an important direction for the transformation of the state power system.This paper introduces the basic content of digital twin,and based on the existing PSDT’s technical frameworks,analyses their security problems layer by layer,and presents several protection measures,so as to provide a reference for technology and management scheme in the construction of PSDT.
