摘要: |
在模块化多电平换流器中,控制系统性能对控制器参数依赖性很强。选择合适的控制参数需要大量的调试,严重影响了系统控制器的设计效率。首先分析了模块化多电平换流器控制策略,对控制系统进行了模块化划分。为了适应模块化多电平换流器控制参数优化,加入状态评估来动态适应运动参数,以改进多目标粒子群算法。将优化算法与电磁暂态仿真程序结合,利用电磁暂态仿真软件计算适应值。实现了Matlab优化程序调用PSCAD,仿真结果验证了该方法在模块化多电平换流器控制参数优化中的有效性。 |

Abstract: |
In modular multilevel converters, the performance of control system strongly depends on the control parameters. It requires a significant amount of testing and debugging to get proper control parameters, which seriously affects the efficiency of controllers. The control strategy of MMC is analyzed and the control system is divided based on the functions. In order to adjust the parameters optimization of MMC controller, the evolutionary state assessment to adjust the PSO parameters is involved, which is to improve the MOPSO algorithm. The electromagnetic transient simulation program is linked to the proposed improved MOPSO to give the results of the optimization objective. This paper realizes the joint invocation between PSCAD and Matlab program, simulation results proof the effectiveness of the proposed method in the parameters optimization of MMC controller. This work is supported by China Southern Power Grid Science and Technology Program:Key Technologies and Engineering Application Research of High-capacity VSC-HVDC (No. CSGTRC-K142031). |
