Embodiment 1

[0039] like figure 1 As shown, the present embodiment provides an on-site operation and maintenance system for a converter valve sub-module, which includes: a plurality of sub-module units 1 , a valve base control layer 7 and a background display and control unit 6 . Among them, each sub-module unit 1 is connected to the valve base control layer 7 through optical fibers, and the valve base control layer 7 performs state monitoring, fault warning, fault preprocessing and control for each sub-module unit; background display and control unit 6 and valve base The control layer 7 is electrically connected to display the relevant information sent by the valve base control layer 7, and is converted into a control system in the state of power failure and maintenance of the converter valve, and the power-on function test of each sub-module unit 1 is carried out to assist each sub-module unit 1. Maintenance work of sub-module unit 1.

[0040]Further, the valve base control layer 7 incl...

Embodiment 2

[0048] This embodiment provides a method for on-site operation and maintenance of a converter valve sub-module, which includes the following steps:

[0049] 1) Set up an on-site operation and maintenance system for the converter valve sub-module, which includes multiple sub-module units, a valve base control layer, and a background display and control unit; the valve base control layer includes an online monitoring unit, a fault warning unit, and a fault preprocessing unit and a control unit, the control unit includes a segment control unit and a core control unit.

[0050] 2) The online monitoring unit in the valve base control layer monitors each sub-module unit in real time, and performs state monitoring, fault warning, fault preprocessing and corresponding control on each of the sub-module units based on the real-time monitoring data.

[0051] Specifically, the following steps are included:

[0052] 2.1) The online monitoring unit monitors each sub-module unit in real tim...

Abstract

The present invention relates to a converter valve sub-module on-site operation and maintenance system and method, which is characterized in that it includes: a plurality of sub-module units, a valve base control layer, and a background display and control unit; each of the sub-module units communicates with the The valve base control layer is connected to the valve base control layer, and the valve base control layer performs state monitoring, fault warning, fault pretreatment and corresponding control on each of the sub-module units; the background display and control unit is electrically connected to the valve base control layer The connection is used to display the relevant information sent by the valve base control layer, and convert it into a control system when the converter valve is powered off for maintenance, and perform a power-on function test on each of the sub-module units. The invention can be widely used in the field of flexible direct current transmission.

Description

technical field [0001] The invention relates to an on-site operation, maintenance and maintenance system and method for a flexible DC converter valve sub-module, which is suitable for a modular multi-level converter sub-module in the field of flexible DC power transmission. Background technique [0002] The core equipment of the flexible DC transmission technology is the converter valve. The sub-module is the basic power unit of the modular multi-level converter valve. It integrates a variety of primary power devices and secondary control boards. The degree of integration and integration is high, and a single converter valve contains a huge number of sub-modules, generally reaching thousands of levels. Therefore, the on-site operation and maintenance and maintenance tasks of sub-modules are large and difficult to operate. [0003] At present, there is no complete system for the operation, maintenance and maintenance of the flexible DC converter valve sub-module. For differen...
