面向实时仿真的上海电网动态等值研究

Dynamic Equivalence Research of Shanghai Power Grid for Real-time Simulation

为建立上海交直流电网RTDS仿真模型,提出面向实时仿真的上海电网动态等值思路和方法。在进行上海外部电网和内部低电压电网等值时,分别采用基于BPA的同调等值方法和基于RTDS的宽频等值方法。通过对等值效果的评估,表明所提思路和方法的有效性和可行性。

In order to establish RTDS-based simulation model for Shanghai AC/DC power grid,this paper proposes the idea and method for the dynamic equivalence of Shanghai power grid oriented for real-time simulation.Coherency-based dynamic equivalence based on BPA and wide-band equivalence based on RTDS are adopted for dynamic equivalence of external network and internal low voltage network of Shanghai Power Grid respectively.The assessment of equivalence effect proves the effectiveness and feasibility of the proposed method.
