摘要：站级控制器是模块化多电平换流器柔性直流输电控制系统的核心部分,与上位机、下层控制器协同配合实现柔性直流输电的可靠控制。对基于MMC-HVDC站级控制器主要功能进行了分析,提出了一种站级控制器硬件结构设计方案,并针对该硬件结构以及功能需求设计了软件程序逻辑。研制了基于该站级控制器的4kV/100kW的MMC-HVDC实验样机,在样机上进行稳态实验以及电压阶跃实验,结果表明系统能够正确快速进行有功类无功类物理量的调节,并能对交流系统故障以及控制器通信故障进行清除,验证了站级控制器硬件结构及程序逻辑的正确性。
Abstract:The station controller is the core of flexible HVDC control system for modular multilevel converter (MMC), which is coordinated with the host computer and lower controller to realize the reliable control of flexible HVDC transmission. In this paper, the main function of station controller based on MMC-HVDC is analyzed, and the hardware architecture design scheme of station controller is proposed. In addition, the software program logic is designed according to the hardware scheme and functional requirement. Furthermore, a 4kV/100kW MMC-HVDC experimental prototype based on the designed station controller is developed, on which several stability and voltage experiments are carried out. The results show that the system can quickly regulate active and reactive physical quantities, and protect system from AC system fault and controller communication fault, which verify the correctness of the designed hardware configuration and program logic of station controller.
