Abstract

The invention relates to a visual inspection and inspection method for the status of power equipment in a converter station, which provides a mobile terminal and a visual identification system, which includes the following steps: inputting the operating conditions of the power equipment, the operating parameters and positions of the PLC and relay indicator lights into the visual In the screening system, the on-off status of the indicator lights in the screen cabinet under the current working conditions is calculated; the mobile terminal collects the on-site picture data of the indicator light of the screen cabinet and transmits it to the visual screening system; Processing, to obtain the actual on-off status of the current screen cabinet indicator; the visual discrimination system judges whether the indicator light is abnormal according to the on-off status of the indicator light in the screen cabinet under the current working conditions and the actual on-off status of the current screen cabinet indicator light, and outputs the judgment result . The invention uses the optimized image recognition algorithm to identify the indicator lights and quickly judges whether each indicator light is abnormal, discovers the early hidden dangers of the equipment in time, and ensures the safety of the system.

Description

technical field

[0001] The invention relates to a method for inspecting and inspecting the state of power equipment of a converter station visually. Background technique

[0002] The converter valve will generate a lot of heat during operation, and a dedicated valve cooling system is required to dissipate it. The converter valve also has high requirements on the working environment, and a special HVAC system is required to keep the temperature, humidity and pressure in the valve hall constant. The failure of the HVAC system will lead to the deterioration of the valve hall environment and endanger the safety of the converter valve; while the serious failure of the valve cooling system can cause the outlet to trip. Therefore, operation and maintenance personnel should pay more attention to the operation status of power equipment in daily inspections, and timely discover and eliminate equipment hidden dangers.

[0003] The power equipment of the flexible DC converter station ...
