Problems solved by technology

The traditional converter valve monitoring equipment system has the following two major disadvantages: First, the signal processing does not distinguish the importance of the signal, and is completed through the same hardware system, so that once the processing hardware fails, neither the monitoring signal nor the control signal can be processed. Second, there is only a remote monitoring function, so that once there is a problem with the communication line, the equipment will not work at all

Embodiment Construction

[0016] The valve-based electronic equipment system solution of the present invention is: divide the interactive signal between the valve-based electronic equipment and the extreme control system of the converter station into two priority levels according to different control functions, that is, for realizing the triggering of the converter valve Control signals for control functions such as lock and lock, and monitoring signals for reporting the operating status of the converter valve. Corresponding to different interactive signals, the system sets up different subsystems for processing, so as to avoid the mutual influence that may be caused by the control signal and the monitoring signal sharing the same control system.

[0017] The chassis structure of the electronic equipment that constitutes the valve base is shown in the appendix figure 1 . System functions are mainly completed by two boards: the main control board and the detection board. The board system diagram is at...

Abstract

The invention relates to the field of high voltage direct current (HVDC), in particular to a novel HVDC thyristor valve base electronic equipment system. In the system, interactive signals between the thyristor valve base electronic equipment and a converter station pole control system are divided into control signals and monitoring signals according to different functional targets. Different types of interactive signals are processed by different hardware sub-systems so as to avoid interactive influence possibly caused by the same control system hardware shared by the control signals and the monitor signals. Furthermore, besides the traditional remote control function, the system is provided with an in-situ control sub-system module realizing an in-situ monitor working mode.

Description

technical field [0001] The invention relates to the field of high voltage direct current transmission (HVDC), in particular to a novel HVDC converter valve valve base electronic equipment system. Background technique [0002] In high-voltage direct current transmission (HVDC), the converter valve valve base electronics is the first-level monitoring device for the converter valve. According to the received control command of the extreme control system, the device directly realizes the triggering and blocking operations of the converter valve, and collects the reported information of each thyristor level in real time, and feeds it back to the extreme control system. The traditional converter valve monitoring equipment system has the following two major disadvantages: First, the signal processing does not distinguish the importance of the signal, and is completed through the same hardware system, so that once the processing hardware fails, neither the monitoring signal nor the ...
