The invention discloses a configuration system and method for a high-voltage flexible direct-current converter valve control apparatus. M bridge arm control panels are controlled through a valve main control apparatus; each bridge arm control panel controls N bridge arm control apparatuses; each bridge arm control apparatus controls P sub module control apparatuses; and each sub module control apparatus controls Q converter valve sub modules, wherein M, N, P and Q are all positive integers. Therefore, configuration of the whole flexible direct-current power transmission converter valve control apparatus by the valve main control apparatus is realized; by detecting the feedback information of the flexible direct-current power transmission converter valve control apparatus, whether each part of the converter valve control apparatus is configured successfully or not can be determined; and the part which is not configured successfully is rapidly positioned, and finally it is ensured that each part is configured successfully.
Description
technical field [0001] The invention relates to the field of flexible direct current transmission engineering, in particular to a configuration system and method for a high-voltage flexible direct current converter valve control device, which is suitable for high voltage levels above ±500kV. Background technique [0002] With the continuous development of high-power power electronics technology, flexible DC transmission equipment based on high-power power electronics has been widely used. The flexible DC converter valve control device is one of the core equipment in the flexible DC power transmission equipment, which is used to control the reliable and stable operation of the flexible DC converter valve and ensure the safety of the converter valve. As the voltage level of the flexible direct current transmission equipment becomes higher and higher, the control device of the flexible direct current converter valve becomes more and more complicated, and contains more and more ...
