Description
Technical Field
The invention belongs to the technical field of high-voltage direct-current transmission engineering, and particularly relates to a state visual monitoring system and a monitoring method of a fault recording device.
Background
The converter valve, being one of the most important devices in the converter station, will have an operational status that is directly related to the safety of the whole dc transmission system. With the increase of high-voltage direct-current transmission projects, faults of the extra-high voltage converter valve are increased, so that the number of unplanned shutdown times of the direct-current project is increased, and the faults become a key for restricting the improvement of reliability indexes of the extra-high voltage direct-current project. Therefore, it can be seen that the importance of the converter station in the high voltage direct current transmission is important, and the pole control system and the main circuit of the converter valve of the converter station play an important role in the converter station, so that it is necessary to make a judgment on the working condition or whether the board card in the VBE (valve base electronics) system is damaged or not at any time to determine that the damage or the working condition is not normal, which becomes the capability that the person in the art should have, but in the prior art, there is no good system or platform for the person in the art to quickly obtain the capability
Meanwhile, due to the lack of process monitoring data, the state change of the VBE system, such as the failure of the optical power device, can not be found in time, so that the fault outage caused by the change can be avoided. When the VBE system breaks down, manpower and material resources and time are consumed for troubleshooting fault points, reliable fault accurate positioning can effectively save the manpower and material resources, and the fault power failure time is shortened.
In the VBE system, a fault recording device is one of important devices, and the recording function is realized by receiving a recording signal and controlling a protected recording start signal. The wave recording case realizes the collection and storage of key interface signals including valve control trigger pulse signals (single valves), return signals (single valves) and exchange optical signals between VBE and polar control, and has important significance for monitoring and troubleshooting of the signals. The fault recording device of the VBE system in operation limits fault troubleshooting capability and deep state analysis due to limited recording time and limited recording file storage capacity. In addition, because the upper computer monitoring system is not arranged, the recording file cannot be directly read and checked, the visualization degree is low, and the on-site operation and maintenance personnel cannot timely find and analyze the state of the VBE system through checking the recording file.
