Embodiment Construction

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0060] In view of the difficulty in manually programming programs one by one at present, the reliability is low, and it consumes a lot of manpower and time resources, the embodiment of the present invention provides a method for initializing the protection fixed value of the power module of the converter valve, which has higher reliability and can save manpower and time resources. The present invention will be described in detail below in conjunction with the ...

Abstract

The invention provides a method and a system for initializing a protection setting value, a valve control device and a power module. The initialization method of the protection setting includes: receiving voltage data from a plurality of power modules; When the sum of the voltage data of the plurality of power modules reaches the preset value, the initialization parameter corresponding to the protection setting value of the power module is outputted to the corresponding power module. Receiving initialization success information from each power module; According to the initialization success information, the initialization stage completion flag is generated and uploaded to the initialization stage completion flag, so that the inverter valve has the ability of batch changing the protection setting value of the power module, the reliability is higher, and the labor and time resources are saved.

Description

technical field [0001] The present invention relates to the field of protection fixed value initialization, in particular to a protection fixed value initialization method and system, a valve control device, and a power module. Background technique [0002] The flexible DC converter valve generally adopts a modular multilevel converter (MMC) topology. The converter valve is composed of six bridge arms in three phases, and each bridge arm is composed of several power modules connected in series. Each power module is equipped with two optical fibers, one for receiving and one for sending, to establish a bidirectional data path and communicate with the valve control device of the converter valve. The control commands from the valve control device control the actions of the devices in the power module; the power module detects its voltage value and judges the failure of each discrete component, and packs it into data and sends it to the valve control device. In the conventional...
