|
摘要
电磁-机电混合仿真可同时实现对大规模电力系统的机电暂态仿真和局部网络的电磁暂态仿真,本文首先分析了混合仿真分割求解的信息量交互基本需求,分别从电磁侧与机电侧两个方面比较了各自边界条件的限制性,并就电磁侧电流源等值形式与功率源等值形式进行了适用性分析。最后,通过基于PSCAD+C的混合仿真平台验证了上述相应分析结论。
The electromagnetic-electromechanical hybrid simulation can realize the electromechanical transient simulation for large-scale power grid and the electromagnetic transient simulation for target system simultaneously. In this paper,the basic requirements of transinformation for grid segmentation process in hybrid simulation are firstly analyzed. From two sides of electromagnetic and electromechanical subsystems,the limits of boundary conditions are also compared respectively,especially the applicability of equivalent current source and power source for electromagnetic subsystem. In the end,the hybrid simulation platform based on PACAD + C is used to verify the above corresponding analysis conclusion.
