Intelligent HVDC Valve Control System Using Partial Reconfiguration Technology

通过对高电压直流输电(HVDC)换流阀控制原理的分析,在目前国内智能电网的发展现状和国际上现场可编程器件(FPGA)最新技术的基础上,提出了一种基于部分重配置技术的HVDC换流阀智能控制系统。该系统基于FPGA的部分重配置技术,使其在稳定工作情况下,可以动态更新智能电网协议设计以及接口设计,避免了传统更新硬件时导致的电网停电和断点;同时部分重配置技术的使用减少了FPGA的资源占用,降低了产品的开发成本。该系统使用SOC架构,增加了系统的灵活性和减少系统研发和调试的时间;其物理层和链路层可实现目前国内智能电网所有主流通信协议,并与现有智能电网进行互联互通;该控制系统目前使用于HVDC换流阀实验和对换流站中换流阀实时监控,但是其成熟稳定的架构也使其可以广泛应用于智能电网的其它设备。

Through the analysis of the HVDC converter valve control system,according to the status of smart grid development of domestic and latest technology of FPGA,we propose an HVDC converter valve intelligent control system on the basis of partial reconfiguration.According to the partial reconfiguration,the system can work in stable state and simultaneously can update or modify its protocol or interface design,so as to avoid shutting down the power.Also partial reconfiguration technology can reduce FPGA resource occupation,reducing product development cost.The SOC architecture can increase the system flexibility and reduce system development and debugging time.Its physical layer and link layer can be realized for all major domestic smart grid communication protocols,and are communicated with the existing smart grid interoperability.The system is currently used in the HVDC converter station and experiments,and its mature and stable system framework can be applied to HCDC converter,but also the other devices in smart grid.
