Abstract

The invention discloses a converter valve TVM plate heating prediction method, system and device and a medium, and relates to the field of DC power transmission control protection. The method comprises: obtaining a TVM plate temperature data model in a valve hall region according to a preset time interval; obtaining a screening model in the valve hall area according to a preset time interval, analyzing the screening model by adopting data correlation, and establishing a temperature prediction model; dividing the temperature prediction model into a training data set and a verification data set,and training the temperature prediction model; and analyzing and judging the temperature prediction model in combination with the TVM board temperature data model, continuously operating monitoring under normal conditions, and giving an abnormal alarm under abnormal conditions. The invention has the advantages that by predicting the heating of the TVM board, abnormal heating of the TVM board canbe found in advance when the temperature of the TVM board is not high, hidden danger of equipment can be found in advance and eliminated, and the risk of faults of a direct-current power transmissionsystem is reduced.

Description

technical field [0001] The invention relates to the field of DC transmission control and protection, in particular to a method, system, device and medium for predicting heat generation of a TVM board of a converter valve. Background technique [0002] The converter valve is the key equipment of DC transmission. In the DC transmission project, it not only has the function of rectification and inverter, but also has the function of switch in the rectification station. It can use its fast and controllable characteristics to start the DC transmission. and outage for quick operation. The basic unit of the converter valve is a thyristor element, and each thyristor element corresponds to a TVM board. In the thyristor valve, the TVM board bears the DC voltage equalization of the thyristor on the one hand, and on the other hand monitors the voltage at both ends of the thyristor, generates relevant check-back signals, and sends them to VBE. The DC divider resistor connected in paral...
