The development of specific software dedicated to simulation of power electronic systems (PSIM, SABER, PSCAD, “SimPowerSystems” toolbox of Simulink…) allows simulating fast and accurately the converter behavior. Unfortunately, the designers of converters don’t always have such available software. In...
Afterward, a benchmark method is proposed that preserves second-order accuracy at switch events. The tools EMTP-RV and PSCAD are compared with this benchmark method for elementary circuit examples. The results demonstrate the potential to improve accuracy, by several orders of magnitude in some ...

Synchronous operation of the transfer branch in a hybrid HVDC breaker (HHB) [36] has been proposed to reduce the adverse effects on the VSC-based DC grid from a DCB reclosing operation under a permanent fault [37]. Specifically, all fully-controlled fast-power electronic switches in the trans...
[50,51,52]. Among them, PSCAD/EMTDC is designed initially for a DC system EMT analysis. Meanwhile PSCAD is also widely used in modeling HVAC and FACTS devices. As the power systems become more and more complex with a large quantity of electronic devices, real time simulations are ...
由于H桥级联的数目是影响谐波分布的重要因素,所以本文利用PSCAD仿真软件,分别搭建了3、5、6、7、10级级联整流桥的仿真模型,并在两种不同的载波移相方式下分析了交流侧电压的频谱分布规律。表2.2给出了在移相180???/n方式下和移相360???/n方式下3、5、6、7、10级级联整流桥的交流侧电压频谱信息,表中数据为...
