基于PSCAD的10 kV电磁式电压互感器铁磁谐振影响因素的仿真与分析
Simulation and Analysis of Ferromagnetic Resonance Influencing Factors of 10 kV Electromagnetic Voltage Transformer Based on PSCAD
摘要
Abstract
In view of the shortcomings of the existing ferroresonance protection measures,the influencing factors of ferroresonance were quantitatively analyzed to determine the key influencing factors,and avoi-ding them in the planning and construction of the power grid,operation and scheduling,which is a measure to prevent ferroresonance in advance.Firstly,the ferroresonance mechanism of electromagnetic Voltage Transformer(VT)was analyzed,and the influencing factors were determined.Then a simulation model of ferroresonance was constructed based on PSCAD,and the feasibility of the model was verified by experiments.Finally,multiple operation modes were used to traverse the main influencing factors of fer-romagnetic resonance on the model,and the importance evaluation index based on probability statistics was constructed and quantified to determine the key influencing factors of electromagnetic VT ferromag-netic.The results show that the fault of dynamic arc grounding and the fault disappearing at the moment of maximum voltage amplitude are the key factors to induce ferromagnetic resonance of electromagnetic VT,and the research results meet the needs of practical engineering and help to prevent and suppress fer-roresonance fault.关键词
