A Novel Topology of Compact Magnetically Controlled Transformer
摘要
The extensive use of cables has led to an increased demand for capacitive reactive power balance within the system. Additionally, the inherent variability of wind energy and solar energy introduces fluctuations in the reactive power balance. This paper introduces a novel topology of compact magnetic control trans-former, its physical footprint is only marginally larger than that of conventional transformers, yet it substantially reduces the land footprint required for reactive power compensation equipment. Finite element simulations were conducted to assess the effectiveness of this magnetic control transformer, revealing that it can provide a reactive power regulation capacity of up to 200 kvar. Furthermore, it exhibits a harmonics content as low as 0.38%. These exceptional performance characteristics render it well-suited to meet the reactive power compensation needs of urban substation or offshore wind energy transmission systems.
