The invention relates to a low-voltage test platform of a power module of a static reactive power compensator. The platform comprises a controller and first to third test branches, a first port of thefirst test branch and a first port of the second test branch are both connected to a first port of the third test branch, a second port of the first test branch is connected with the power grid, a second port of the second test branch is connected with the power module to be tested, a second port of the third test branch is connected with a load power module, the load power module is connected with the controller, and the controller is used to control the power module to be tested to compensate the load power module. The power module test platform is simple in structure, the power module to be tested can be tested only via one controller, three test branches and one load power module, and in the test process, reactive power emitted or absorbed by the load power module is recovered by thepower grid, resource waste is avoided, and the economic cost is saved.
Description
technical field [0001] The invention belongs to the technical field of test devices for reactive power compensation devices, and in particular relates to a low-voltage test platform for power modules of static reactive power compensation devices. Background technique [0002] At present, the power module test platform of the reactive power compensation device is mainly the detection platform of the performance index of a single module, which has certain defects in the stability and reliability of the operation, especially the faulty module connected in series to the entire system of the reactive power compensation device When, there is immeasurable hidden danger to whole set of equipment. In the prior art, the low-voltage experiment platform of the power module of the SVG reactive power compensation device is mainly controlled by a controller of the SVG reactive power compensation device to control the power module to forcibly output reactive power, so as to achieve the purp...
