Matlab/Simulink代码生成技术在RTDS上的应用

Application of Matlab/Simulink-based code generation technology in RTDS

针对实际电力系统运行和控制的复杂性与Matlab仿真非实时性的矛盾,提出跨平台联合仿真。采用基于Matlab/Simulink代码生成技术与RTDS实时仿真系统相结合的方法,以高压直流输电系统模型为研究对象,利用Embedded Coder开发工具对系统的控制模块进行代码生成,并在RTDS中完成代码移植实验。通过对比仿真波形,验证得到结果行为一致。由此表明,该方法能够有效利用Simulink良好的开发环境和RTDS的实时仿真特性,在离线仿真成功的基础上,完成实时仿真测试,使工作便捷高效,同时保证结果精准可信。

In view of the contradiction between the complexity of actual power system operation and control and the nonreal-time characteristic of Matlab simulation,the cross-platform co-simulation is proposed. A method on the basis of the combination of Matlab/Simulink-based code generation technology and RTDS-based(real time digital simulator) real-time simulation system is adopted. By taking the high voltage DC transmission system model as the research object,the development tool Embedded Coder is used to generate code for the control module of the system and complete the code transplantation experiment in RTDS. It is verified that the result and the behavior are consistent by contrasting the simulation waveforms.Therefore,it shows that the proposed method can effectively utilize the excellent development environment of Simulink and the real-time simulation characteristics of RTDS to complete real-time simulation test on the basis of successful off-line simulation,which makes the work convenient and efficient and ensures the accuracy and credibility of the results.
