Method for building static pressure equalizing model of flexible direct-current converter valve

The invention discloses a method for building a static pressure equalizing model of a flexible direct-current converter valve. The method comprises the following steps: a valve section model Rc and a waterway model is built; the valve section model Rc comprises a plurality of submodule models which are connected in series, and equipotential electrodes are arranged at the two ends of the valve section model Rc respectively; the equipotential electrode cuts the waterway model into equivalent resistance Rs of a to-ground waterway, equivalent resistance Rd of a vertical waterway between valve layers and equivalent resistance Rh of a transverse water pipe between the valve layers; the valve section model Rc and the valve interlayer transverse water pipe equivalent resistor Rh are connected in parallel to form a parallel structure, and the parallel structure of the Rc and the Rh is connected in parallel with the valve interlayer vertical water path equivalent resistor Rd; and a stray parameter model is established.
