Abstract

The invention relates to a parameter optimization configuration method for a modular multilevel DC transmission system. According to the method, parameters of primary devices of the modular multilevel DC transmission system are all related according to a theoretical mathematical relation, a repeated iteration adjustment and verification method is adopted, land occupation and cost are integrated, and parameter optimization configuration for the whole system is realized. a whole set of parameter optimization configuration scheme is provided for a modular multilevel DC transmission project; risks to the project by one-sided device parameter selection can be reduced; and the direct correlation between the system parameters and the system operation performance is disclosed.

Description

technical field [0001] The invention relates to an optimal configuration method of a direct current transmission system, in particular to a parameter optimization configuration method of a modularized multilevel direct current transmission system. Background technique [0002] The flexible application performance of flexible DC makes it have extremely broad application prospects in the fields of urban grid interconnection, new energy grid connection, and passive load power supply. Modular multilevel converters are currently the most widely used in flexible DC projects. One of the converter topologies. Each bridge arm of the modular multi-level has the same number of sub-modules connected in series with the bridge arm reactance. By controlling the input and cut-out of the sub-modules, the output voltage is close to the sinusoidal AC voltage, thus forming a stable operating point. At the same time, through the complementary input capacitors of the upper and lower bridge arms ...
