谐波干扰是是电力系统中各种设备故障和经济损失的一个主要来源,而谐波干扰的仿真是电力系统谐波干扰检测算法理论研究的重要基础。将PSCAD(Power Systems Computer Aided Design)仿真技术应用于谐波干扰的仿真中,可以通过调整各种仿真参数,对谐波干扰进行动态仿真。与MATLAB对谐波的仿真效果相比,在PSCAD环境下仿真的谐波干扰信号更加贴近实际。应用PSCAD软件可实现谐波干扰信号的动态仿真,有利于谐波干扰检测的理论研究,为谐波干扰检测算法的研究和提出提供动态可靠的仿真数据。

Harmonics is a main source of equipment damage and huge economic loss in power systems, and the simulation of harmonics is an important foundation of theory research in harmonics. In this paper, the PSCAD （Power Systems Computer Aided Design） simulation technology is applied to simulate harmonics by adjusting simulation parameters. Compared with mathematical simulation method based on MATLAB, power disturbances simulated in PSCAD simulation environment appear in actual power systems. The application of PSCAD in the real-time simulation of harmonics plays a vital role for realizing the dynamic simulation of harmonics, which is beneficial to the theory research of harmonics and the introduction of novel harmonics detection algorithms.
