Design and Application Technology of Virtual Sensor for Digital Twinning of High Voltage Equipment
摘要
Abstract
As for such demand as model construction,information interaction and dynamic simulation of digital twin-ning of high voltage equipment,the design and application technology of virtual sensor are analyzed.Virtual sensor is a computer simulation system with sensor behavior,which can decouple complex digital twin system based on func-tion,structure and service requirements as well as reduce the complexity of engineering application.In this paper,the design requirements of the virtual sensor applied to the digital twin engineering of high voltage equipment are pro-posed,the design and application methods of the virtual sensor for observation,the virtual sensor for parameter calcu-lation and the virtual sensor for prediction and alarm are given.The study results show that the virtual sensor has such advantages as componentization,service,easy reconfiguration and evolution,the function can be used as a digi-tal twin cell level component design method so to solve the difficulties in data acquisition and fusion,the complicated coupling of simulation and prediction algorithms in current engineering applications,support the applications of com-prehensive equipment state perception,accurate trend prediction,early risk warning and equipment life-cycle lean management.关键词
