Embodiment Construction
[0104] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0105] In the general model building process, because the equipment is in a complex electromagnetic environment, the lumped parameter model in the traditional sense alone cannot reflect the broadband characteristics of the equipment, which will make the calculation results inaccurate. The invention provides a method for predicting electromagnetic interference in UHV converter stations, which calculates electromagnetic interference based on the establishment of equivalent circuits, and also includes measurement of node impedance, establishment of equivalent circuits, calculation of transient currents, and any position of UHV converter stations For the calculation of electromagnetic interference, the node impedance is a frequency domain function, which breaks the limitation of centralized parameters and reflects the characteristics of the eq...
