摘要:  摘  要: 首先分析了多端口耦合给机电-电磁暂态混合仿真造成的误差机理,推导了不考虑直流电流变化及考虑直流电流变化情况下端口之间的耦合关系。然后,为减小多端口建模引入的仿真误差,并在满足RTDS建模约束下尽可能地保证电磁侧的仿真精度,针对机电-电磁暂态混合仿真电磁侧建模进行了多端口解耦指标的研究。分别对不同耦合强度的端口解耦,采用FSV(feature selected validation)方法分析了端口耦合强度和仿真精度之间的定量关系,得到了满足FSV定性评估为“好”及以上的端口解耦指标。最后在基于某地区500 kV及以上电压等级复杂交直流电网建立的实时混合仿真平台上验证了所提解耦指标的有效性。

Abstract:  ABSTRACT:  This paper firstly analyzes the error mechanism of electromechanical and electromagnetic hybrid simulation caused by the multi-port coupling, and deduces the coupling relationship between ports with and without the change of DC current considered. Then, to reduce the simulation error caused by coupled multi-port modeling and ensure the simulation accuracy within the limitation of modeling ability of RTDS as much as possible, this paper studies the multi-port decoupling index for the electromagnetic side in electromechanical and electromagnetic transient hybrid simulation. According to port decoupling with different coupling strengths, this paper adopts feature selected validation (FSV) method to analyze the quantitative relationship between port coupling strength and simulation precision, and obtains the decoupling index of ports which fulfills the ‘good’ standard validated by FSV. Finally, the validity of the proposed decoupling index is validated through the real time hybrid simulation platform of complex 500 kV and above AC/DC power network in a certain area.
