Current conversion controller tester of wind generating set and detection method thereof

Abstract

The invention relates to a current conversion controller tester of a wind generating set and a detection method of the current conversion controller tester. The tester comprises a signal interface board, a central control board and a control key installation board, wherein the signal interface board is connected with a current conversion controller through cables, the central control board is connected with the signal interface board to perform setting or failure judgment on signals, and the control key installation board is connected with the central control board. The central control board comprises a power supply generating circuit, an analog signal detection circuit and a digital signal detection signal. The digital signal detection circuit comprises a plurality of IGBT units. The method includes the following steps that the current conversion controller is connected with the tester; the current conversion controller and a power switch of the tester are turned off, and switches of modules needing to be tested of the tester are turned on; the power switch of the tester and a power switch of the current conversion controller are sequentially turned on; according to indicator lamps, whether the modules to be tested fail or not is judged. The tester can perform all-round testing on the current conversion controller, is convenient to maintain and capable of performing setting on the signals, and solves the problem that in the prior art, a signal generator needs to be used for connection.

Description

technical field [0001] The invention relates to the field of testing of wind power generating equipment, in particular to a tester for a converter controller of a wind power generating set and a detection method thereof. Background technique [0002] The rapid development of the wind power industry has also brought about a serious consumption of spare parts. In order to ensure that wind power manufacturers have lower operating costs, spare parts maintenance manufacturers have sprung up everywhere, and the maintenance technology is also uneven. The industrial control equipment in the wind power industry has the characteristics of difficult maintenance and complex faults, which cause great difficulties for maintenance. The maintenance of existing industrial control devices can only rely on traditional instruments and meters: oscilloscopes, multimeters, function signal generators and logic analyzers, etc. The input and output of signals can only be led out by cables when testin...
