论文摘要
随着大规模混合AC-DC网格的存在，需要电磁瞬态（EMT）模拟来准确描述系统的动力学。但是，当系统尺度较大时，混合AC-DC系统的EMT稳态初始化非常困难，并且耗时。为了提供具有非线性组件和黑盒组件的EMT模拟的稳定快照，本文提出了一种通用的EMT模拟（EMT-GIS）的初始初始化方案（EMT-GIS），该方案可以在电磁瞬态程序（EMTP）型模拟器中实现。首先，引入了集成功率流（IPF）算法以提供稳态结果。然后，为EMT-GI设计了初始化的快照计算和切割机制。拟议的EMT-GIS使用中国在Cloudpss模拟平台上的混合AC-DC系统进行了测试。测试结果验证了拟议的EMT-GIS的有效性。
With the large-scale hybrid AC-DC grids coming into being, electromagnetic transient (EMT) simulation is required to accurately describe the dynamics of systems. However, the EMT steady-state initialization for hybrid AC-DC system is difficult and time-consuming when the system scale is huge. In order to provide a stable snapshot for EMT simulation with nonlinear components and black-box components, this paper proposes a general initialization scheme for EMT simulation (EMT-GIS) which can be implemented in the electromagnetic transient program (EMTP)-type simulators. First, an integrated power flow (IPF) algorithm is introduced to provide the steady-state results. Then, an initialized snapshot calculation-and-splicing mechanism is designed for EMT-GIS. The proposed EMT-GIS is tested using a hybrid AC-DC system in China on the CloudPSS simulation platform. Test results verify the effectiveness of the proposed EMT-GIS.
