dSPACE based test method for wind power converter controller

Abstract

The invention discloses a dSPACE based test method for a wind power converter controller, and relates to test methods for wind power converter controllers. According to the method, dSPACE is configured to be a controlled object such as a wind power converter, a power grid, a power generator or the like, and the controlled object is connected with the converter controller through an interface circuit, so that hardware and software of the wind power converter controller are tested. The test method belongs to semi-physical simulation; compared with pure simulation, the controller is a product-level controller, so that the test method can test a control algorithm and the hardware of the controller as well as a control code; and compared with a field test, the test method conveniently performs various limit tests such as tests of phase failure, short circuit and the like possibly causing damage to the converter, and tests with relatively high test expenses or difficultly established test conditions, such as a low voltage ride through test, a high voltage ride through test, a power grid adaptability test and the like. The test method is suitable for testing the software and the hardware of the wind power converter controller.

Description

technical field [0001] The invention relates to a testing method for a controller of a wind power converter, belonging to the technical field of new energy grid-connected power generation. Background technique [0002] At present, there are two main testing methods for wind power converter controllers: [0003] One is to use simulation software such as Matlab / Simulink, PSCAD, etc. to perform simulation tests. This test method can facilitate the manufacture of various test conditions and verify the control strategy; however, this test method cannot verify the controller hardware, and The verified control strategy needs to be converted into controller code first, and then a detailed on-site test is carried out before it can be applied to the product. The conversion of the control strategy to the controller code is unavoidable due to human error, and only part of the core control strategy is verified in the simulation, and other simple auxiliary functions still need to be test...

[0004] The second is to test on site. This test method can comprehensively test the software and hardware of the converter controller. After the test is passed, the controller can be directly applied to the product. tests that may cause damage to the converter), tests that are expensive or difficult to set up (such as low-voltage ride-through tests, high-voltage ride-through tests, grid adaptability tests, etc.), the cost of on-site testing is too high, and it is safe sex is difficult to ensure
