考虑容性无功补偿与暂态振荡抑制的多速率接口变压器模型
Model of a Multi-rate Interface Transformer Incorporating Considerations for Capacitive Reactive Power Compensation and Transient Oscillation Suppression
摘要
Abstract
Simulation research is vital for renewable power systems,particularly full electromagnetic transient simulation.Single-rate simulation is inefficient because of the small time step required for high-frequency devices,leading to the development of multi-rate simulation.The multi-rate interface transformer,a crucial component,decouples large systems into subsystems operating at different rates.However,existing multi-rate interface transformers present challenges such as excessive capacitive reactive power and transient oscillations due to the introduction of virtual capacitors.To address these issues,this paper introduces a novel multi-rate interface transformer model.By incorporating additional inductances on both sides of the transformer to compensate for the excessive capacitive reactive power generated by the virtual capacitors,and adding resistances to quickly dampen the oscillation energy,the model effectively mitigates transient oscillations.Testing conducted on the RTDS platform demonstrates that,compared to traditional multi-rate interface transformers,this model reduces excessive capacitive reactive power by approximately 92.04%and transient oscillation amplitudes by an average of 81.46%.关键词
