随着基于模块化多电平换流器(modular multi-level converter,MMC)的柔性直流输电系统成为新型电力系统建设的重要组成部分,研发MMC型柔性直流输电系统的精确仿真工具成为一种迫切需求.文章聚焦于研究可接入实际柔直控制保护装置的具有高仿真精度柔直数模混合仿真技术,提出一种基于服务器端数字阀模型的柔直数模混合仿真架构,并基于电力系统全数字仿真装置(advanced digital power system simulator,ADPSS)开发了一种MMC数字阀体阀控仿真加速技术,实现了基于多核中央处理器(central processing unit,CPU)的MMC实时仿真技术,提高了柔直数模仿真系统的灵活性和易用性.基于该文提出的架构建立了渝鄂±420kV背靠背柔直数模混合仿真模型,通过与现场试验结果进行波形比对,验证了基于该架构的ADPSS柔直数模混合仿真系统的精确性,为今后开展含柔性直流的大电网仿真提供了技术支撑.
As MMC-HVDC transmission technology based on Modular Multilevel Converter(MMC)becomes an important component of new power systems,the development of accurate simulation tools for MMC-HVDC transmission systems has become an urgent need.This paper focuses on the research of high simulation accuracy digital-analog hybrid simulation technology that can be integrated into actual control and protection devices.MMC-HVDC digital-analog hybrid simulation architecture based on a server-side digital valve model is proposed.An MMC digital valve body control simulation acceleration technology is developed based on the domestic real-time simulation software ADPSS.The MMC real-time simulation technology based on multi-core CPU servers is realized,improving the flexibility and usability of the MMC-HVDC digital-analog platform.Based on the architecture proposed in this paper,Yu to E±420kV back-to-back MMC-HVDC transmission digital-analog hybrid simulation model was established.Simulation tests were conducted on the established model to verify the accuracy of the ADPSS MMC-HVDC digital-analog hybrid simulation platform based on this architecture,providing technical support for future simulations of large power grids containing MMC-HVDC.
