The invention provides a function test system suitable for an MMC valve base controller. The function test system uses the function unit of the MMC valve base controller as a test object. The function test system comprises an interface layer, a model layer, a control layer and an operation layer. The interface layer is connected with the test object and the model layer. The model layer constructs a digital model. The control layer reports the digital model to the operation layer. The operation layer controls the control layer to operate the digital model. Compared with the prior art, the function test system suitable for the MMC valve base controller, which is provided by the invention has the advantages that the function of the valve base controller is used as the test object; the function unit is used as the object to carry out in-depth test on the valve base controller; the valve base controller in a secondary system has the capacity of continuous and stable operation; the hardware reliability and safety of the whole set of the valve base controller VBC are ensured; and a converter valve is well controlled and protected.
Description
technical field [0001] The invention relates to the field of flexible direct current transmission, in particular to a function test system suitable for MMC valve base controllers. Background technique [0002] In the flexible direct current transmission project, the valve base controller VBC suitable for the modular multilevel converter MMC is responsible for the control and protection of the converter valve, and is one of the most important components in the secondary system. It must have continuous, Stable operation ability. The current test method for the valve-based controller VBC is mainly to build a low-voltage, low-current flexible DC converter station dynamic model platform in the laboratory to simulate the working conditions of the converter station in the actual project, so that the hardware of the entire set of VBC is reliable. Performance, control strategy, protection strategy, etc. are verified as a whole; while the VBC suitable for MMC is a secondary device wi...
