Abstract

The invention provides a program on-line programming system for a multimedia card (MMC) flexible direct-current power transmission valve base controller. The program on-line programming system comprises function board cards 1, function board cards 2 and a connecting board, wherein the function board cards 1 and the function board cards 2 are arranged in parallel, and the connecting board is respectively connected with the function board cards 1 and the function board cards 2. The program on-line programming system for the valve base controller for a high-capacity MMC flexible direct-current power transmission converter has the advantages that program programming modes are flexible and diverse and do not interfere with each other.

Description

technical field [0001] The invention belongs to the field of flexible direct current transmission, and in particular relates to an MMC flexible direct current transmission valve-based controller program online programming system. Background technique [0002] Flexible DC transmission technology is a new type of DC transmission technology based on voltage source converters, controllable turn-off devices and pulse width modulation (PWM) technology. In order to ensure the safe and stable operation of converter valve components, the valve base controller mostly uses logic smart chips such as DSP and FPGA for data processing, control and protection logic operations, etc. For large-capacity MMC flexible direct current transmission systems, the number of converter valves is huge, and the number of valve-based controller chassis is large. If the program is programmed for a single logic chip on the board, the work will be heavy. It is of great significance to study how to realize th...
