Embodiment 1

[0042] The embodiment of the present invention provides a method for online monitoring and evaluation of a converter valve, which is applied to occasions where safe operation and maintenance of the converter valve and the valve hall are required, such as figure 1 shown, including:

[0043] Step S11: Using various monitoring devices to monitor the operating status of the converter valve and the environmental status of the valve hall of the converter valve in real time, and obtain the operating status information of the converter valve and the environmental status information of the valve hall of the converter valve.

[0044] Since the converter valve body is complex and huge, and the valve hall of the converter valve contains various support systems such as water cooling system and heat dissipation system, various faults may occur in the converter valve and the valve hall. Various types of faults are comprehensively analyzed, and a variety of monitoring equipment is used to mon...

Embodiment 2

[0112] An embodiment of the present invention provides a system for online monitoring and evaluation of a converter valve, such as Figure 12 shown, including:

[0113] The information collection module 1 is used to monitor the operating status of the converter valve and the environmental status of the valve hall of the converter valve by using various monitoring equipment, and obtain the operating status information of the converter valve and the environmental status information of the valve hall of the converter valve; this module implements the embodiment The method described in step S1 in 1 will not be repeated here.

[0114] The fault identification and tracking module 2 is used to identify whether the environment of the valve hall of the converter valve is faulty by using the preset fault judgment method according to the environment status information of the valve hall of the converter valve. The preset fault target tracking method tracks and locates the fault points, and...

Embodiment 3

[0120] An embodiment of the present invention provides a computer device, such as Figure 14 As shown, it includes: at least one processor 401 , such as a CPU (Central Processing Unit, central processing unit), at least one communication interface 403 , memory 404 , and at least one communication bus 402 . Wherein, the communication bus 402 is used to realize connection and communication between these components. Wherein, the communication interface 403 may include a display screen (Display) and a keyboard (Keyboard), and the optional communication interface 403 may also include a standard wired interface and a wireless interface. The memory 404 may be a high-speed RAM memory (Ramdom Access Memory, volatile random access memory), or a non-volatile memory (non-volatile memory), such as at least one disk memory. Optionally, the memory 404 may also be at least one storage device located away from the aforementioned processor 401 . The processor 401 can execute the method for on...

Abstract

The invention discloses a converter valve online monitoring and evaluating method and system. The method comprises the steps that the operating state of a converter valve and the valve hall environment state of the converter valve are monitored and obtained by using a plurality of monitoring devices; a preset fault judgment method is utilized to identify whether the converter valve hall environment is faulty, and fault points are tracked and positioned by using a plurality of preset fault target tracking methods to obtain a fault recognition result and a fault tracking positioning result; andaccording to the operation state information of the converter valve, a preset evaluation method is utilized to perform preliminary evaluation on the fault recognition result and the fault tracking positioning result obtained by the plurality of preset fault target tracking methods, and the comprehensive evaluation is performed again according to each preliminary evaluation result to obtain an evaluation result. Therefore, schedule maintenance of the converter valve is changed into state maintenance, the outage and maintenance time of a direct current system are reduced, and the operation stability of the converter valve is improved.

Description

technical field [0001] The invention relates to the fields of power electronics, power systems and image processing, in particular to a method and system for on-line monitoring and evaluation of a converter valve. Background technique [0002] As the core equipment of the DC transmission system, the converter valves are the key factors to ensure the operation reliability, availability and operation and maintenance efficiency of the DC transmission system. Due to the strong magnetic field and large noise in the valve hall of the converter station, the traditional manual inspection method has the disadvantages of harsh inspection environment, high labor intensity, high risk and low work efficiency, and the inspection results are easily affected by the subjective influence of operators The problem. At present, the UHV converter station is equipped with an industrial video monitoring system. The monitoring system initially realizes the real-time monitoring of the video inside t...
