摘　　要：为了准确模拟实际直流系统的运行特性,提出了基于工程平台HCM3000的全数字仿真建模方法。首先,介绍了仿真建模总体方案,说明了工程平台建模流程。其次,对由硬件装置实现的功能进行数字模拟,对图形化软件程序的通信接口进行改造,并转换为仿真可执行程序;通过任务调用程序,实现控制保护代码的有序调用。最后,以扎鲁特-青州特高压直流工程为例,建立直流系统仿真模型,完成大量功能性能试验,并与实际工程现场波形比对。对比结果表明,仿真模型与实际工程运行特性高度一致,验证了全数字仿真建模的准确性、有效性,能够再现直流工程的运行特性,对于实际工程的运行和维护具有重要的指导价值。In order to simulate the operating characteristics of actual DC system accurately,a full-digital simulation modeling method is proposed based on HCM3000 control and protection platform.Firstly,simulation modeling scheme is introduced,which explains the modeling process of project platform.Secondly,the function realized by hardware device is simulated digitally.Communication interface of the graphical software program is modified and then converted into simulation executable program.Through the task calling program,the order calling of control and protection codes is realized.Finally,taking Zhalute-Qingzhou UHVDC transmission project as an example,DC system simulation model is established.A large number of function performance tests and comparison with actual project waveforms are completed.Results show that simulation model is highly consistent with actual project operating characteristics,which verifies the accuracy and effectiveness of full-digital simulation model.It can reproduce operating characteristics of DC system,which has important guiding value for actual project operation and maintenance.
