Abstract

The invention relates to a power module testing system and method in a flexible alternating current and direct current power transmission system. The power module testing system comprises a power module, a power module testing device and upper-layer control equipment, the power module is connected with the upper-layer control equipment, the upper-layer control equipment is connected with the power module testing device, wherein the power module testing device sends a testing instruction to the power module through the upper layer control equipment; the upper-layer control equipment forwards the test instruction from the power module test device to the power module and receives state information from the power module; and the power module testing device obtains the state information of the power module through the upper-layer control equipment. According to the power module test system and method provided by the invention, the test efficiency can be improved, and the test time consumption can be reduced.

Description

technical field [0001] The present application relates to the field of flexible power transmission, in particular to a power module testing system and testing method. Background technique [0002] At present, in the field of flexible power transmission applications, flexible DC converters and chain-type reactive power compensation devices mostly adopt modular designs. With the increase of capacity and voltage level, the number of system power modules can reach hundreds or even thousands. Efficient and fast testing of power modules is particularly important. [0003] However, due to the distance between the upper control equipment and the power module, it is difficult to perform on-site maintenance and testing of the system without changing the original electrical and communication connections. The general practice in the prior art is that when the power module needs to be tested, the communication connection between the power module and the upper control equipment needs to ...
