一种可灵活配置的MMC子模块功能检测装置及方法
摘要：
本发明公开了一种可灵活配置的MMC子模块功能检测装置及方法，包括可控直流源、被测MMC子模块、电抗器和控保装置；其中，被测MMC子模块包括主MMC子模块和从MMC子模块，主MMC子模块和从MMC子模块分别通过光纤连接到控保装置，接收控保装置的控制指令，并将被测MMC子模块的电压、电流及状态信息上传至控保装置。本发明提供的可灵活配置的MMC子模块功能检测装置可针对不同结构的MMC子模块，灵活设置检测模式，参数和模式调节方式便捷；可同时兼容柔性直流配电网AC/DC换流阀中的半桥结构MMC子模块和全桥结构MMC子模块，检验不同拓扑结构MMC子模块在长时间额定运行工况下的技术性能、保护和通信等功能，从而满足柔性直流配电网AC/DC换流阀中MMC子模块的稳态运行要求。
摘要（英）：

The invention discloses a flexible-configuration MMC submodule function detection device and method. The device comprises a controllable direct-current source, detected MMC submodules, a reactor and acontrol protection device, wherein the detected MMC submodules include a master MMC submodule and a slave MMC submodule, the master MMC submodule and the slave MMC submodule are connected to the control protection device through optical fibers respectively to receive a control instruction of the control protection device, and voltage, current and state information of the detected MMC submodules is uploaded to the control protection device. Through the flexible-configuration MMC submodule function detection device, detection modes can be flexibly set for the MMC submodules with different structures, and parameter and mode adjustment modes are convenient to use; and the device can be compatible simultaneously with half-bridge structure MMC submodules and full-bridge structure MMC submodulesin AC/DC converter valves of a flexible direct-current distribution network to detect technological properties, protection, communication and other functions of the MMC submodules with different topological structures under a long-time rated running condition, thereby meeting the requirement for steady running of the MMC submodules in the AC/DC converter valves of the flexible direct-current distribution network.
