Interactive Design and Application of Virtual Training System for Smart Substation Combining Configuration Algorithm and Digital Twin Technology

Power system simulation training is one of the important means to improve the quality of operators and ensure the safe and effective operation of power systems.Research based on digital twin technology, combined with configuration algorithms to give the substation integration diagram model generation method, developed a smart substation virtual training system.The intelligent monitoring is studied, the digital twin-based substation output voltage anomaly detection method is designed using the tracking differentiator method, and finally the simulation test of the intelligent substation virtual training system is carried out.The analysis shows that the voltage anomaly detection method in this paper is highly accurate and can extract the voltage anomaly waveform, and the offset rate of its collected signal is significantly lower than that of the comparison method (11.58%~14.84%),which is only 0.54%.The training test of fast distance protection, differential protection and zero sequence protection verifies the feasibility and effectiveness of the virtual training system in practical application.The platform can effectively promote the reform of applied electric power practice courses and provide a backbone for the training of new power system talents.
