The invention belongs to the technical field of frequency converters, and discloses an optical fiber series high-voltage frequency converter and a control method thereof. The high-voltage inverter includes a main control module and one-phase or multi-phase power modules; each phase power module includes one or more power units connected in series in sequence, and when a power unit fails, a preset fault frame is generated, and the preset fault The frame is sent to the secondary power unit connected to the power unit, and the secondary power unit transmits the preset fault frame to the main control module through data transparent transmission; when the main control module receives the preset fault frame, it sends the preset fault frame to each power unit. In the command frame, the fault diagnosis is performed according to the fault information fed back by each power unit. The invention transmits the fault signal to each unit and module of the series circuit quickly through data transparent transmission, and the main control module can quickly send the corresponding command according to the fault signal to obtain the fault information, and diagnose the fault information, so as to realize the optical fiber series connection. Rapid fault diagnosis of high-voltage inverters.
Description
technical field [0001] The invention relates to the technical field of frequency converters, in particular to an optical fiber series high-voltage frequency converter and a control method thereof. Background technique [0002] Compared with the parallel type, the optical fiber series high-voltage inverter reduces the number of optical fiber transceivers and the length of optical fibers, saving costs. The fault upload method of each power unit of the existing optical fiber series high-voltage inverter is usually as follows: No. M.1 unit (M represents the three phases of A, B, and C) transmits the fault data to M. Unit 2 analyzes the fault data of unit M.1 after receiving it, and obtains the analysis result, and then packs the analysis result together with the fault data of unit M.2 into a data frame and transmits it to unit M.3. Each unit uses the same method to analyze, pack, and upload fault data in sequence, and finally transmits the fault data and all analysis results to...
