摘要（英）：

The invention provides a decoupling method for an MMC converter valve digital-analog hybrid simulation interface network. An MMC converter valve digital-analog hybrid simulation interface network comprises an MMC digital-analog hybrid digital simulation network, an MMC digital-analog hybrid simulation power interface, and an MMC digital-analog hybrid physical simulation network. The decoupling method comprises the following steps: establishing an MMC digital-analog hybrid digital simulation network; establishing an MMC digital-analog hybrid physical simulation network; and decoupling an MMC converter valve digital-analog hybrid simulation interface network. Through a transmission line interface decoupling algorithm and through flexible adjustment of the position of a converter transformer in MMC converter valve digital-analog hybrid simulation interface decoupling, MMC converter valve digital-analog hybrid simulation delay compensation under the condition of short circuit or no circuit is realized, the decoupling location of an MMC-based flexible DC transmission system digital-analog hybrid simulation interface can be selected more flexibly, a converter transformer can be simulated at a digital side, and the problem that it is hard to simulate a converter transformer at a physical side is solved.
