Abstract

The embodiment of the invention relates to the field of electric power, and discloses a simulation method and a simulation platform of a direct-current transformer and a readable storage medium. The simulation method of the direct-current transformer is applied to a simulation platform, and comprises: constructing a first simulation circuit, wherein the first simulation circuit is used for simulating an equivalent circuit of normal dual-active full-bridge DAB converters in the direct-current transformer, and the number of the normal DAB converters is larger than zero; constructing a second simulation circuit, wherein the second simulation circuit is used for simulating an actual circuit of the faulted DAB converter in the direct-current transformer; and cascading the first simulation circuit and the second simulation circuit to obtain a simulation circuit of the direct-current transformer. According to the embodiment of the invention, the direct-current transformer can be simulated accurately in real time.

Description

technical field [0001] The embodiments of the present invention relate to the field of electric power, and in particular to a simulation method, simulation platform and readable storage medium of a DC transformer. Background technique [0002] Due to its excellent characteristics in various aspects, DC power transmission and distribution technology has become a research hotspot in recent years. As a key equipment of AC and DC power transmission and distribution network, DC transformer has also received extensive attention. A DC transformer generally adopts a structure in which multiple dual-active-bridge ("DAB" for short) converters are cascaded. Due to the size and complexity of high-voltage and large-capacity power electronic devices used in power grids, it is usually impossible to conduct direct experimental research, and the construction period is long and the construction cost is high. With the development of computer technology, advanced digital model simulation techn...
