摘　　要：针对传统的变电站二次回路监测方法存在实时性差、监测过程准确率低的问题,设计了一种基于VR技术的变电站二次回路在线监测方法。首先,利用VR技术模拟变电站实际情况,对环境信息进行三维采集,建立相应的虚拟环境模型,根据其中的各主要状态参量实现变电站监测信息融合;在此基础上,建立回路状态判断指标,对变电站二次回路状态进行判定,得到变电站二次回路安全等级信息。将其与警戒值进行对比,若等级信息超出警戒值,则代表回路中存在故障,需及时处理或检查,若等级信息小于该警戒值则代表回路状态安全,由此实现基于VR技术的变电站二次回路在线监测方法的设计。实验对比结果表明,该监测方法在监测实时性和准确性两个方面具有明显优势,能够及时、准确地发现变电站二次回路中的故障问题,为变电站检修和维护提供支持。Aiming at the problems of poor real-time performance and low accuracy in the monitoring process of the traditional substation secondary circuit monitoring method,an online monitoring method of substation secondary circuit based on VR technology is designed.Firstly,VR technology is used to simulate the actual situation of substation,collect the environment information in three dimensions,establish the corresponding virtual environment model,and realize the substation monitoring information fusion according to the main state parameters.On this basis,the circuit state judgment index is established to judge the secondary circuit state of the substation,and the safety level information of the secondary circuit of the substation is obtained.If the level information exceeds the warning value,it means that there is a fault in the circuit,which should be timely processed or checked.If the level information is less than the warning value,it means that the state of the circuit is safe.Therefore,the design of online monitoring method for secondary circuit of substation based on VR technology can be realized.The experimental results show that this monitoring method has obvious advantages in real-time monitoring and accuracy monitoring,and can timely and accurately find the fault problems in the secondary circuit of substation,providing support for substation maintenance and repair.
