暂态稳定仿真的质量矩阵微分代数方程
Mass-Matrix Differential-Algebraic Equation Formulation for Transient Stability Simulation
摘要：
这封信提出了一个质量矩阵微分代数方程（DAE）制定的暂态稳定仿真。该公式具有两个突出的优点：与大量的隐式DAE求解器兼容，并且可以方便地基于传统公式来实现，例如，通过将质量矩阵中的参数分离到质量矩阵的对角线中。它还允许使用空时间常数来减少动态。基准研究的时间和精度的17个隐式求解器的建议制定使用昆都尔的两个区域系统和2,000总线系统。
英文摘要：
This letter proposes a mass-matrix differential-algebraic equation (DAE) formulation for transient stability simulation. This formulation has two prominent advantages: compatible with a multitude of implicit DAE solvers and can be conveniently implemented based on the traditional formulation, for example, by separating the parameters in denominators into the diagonals of the mass matrix. It also allows reducing the dynamics using null time constants. Benchmark studies are presented on the time and accuracy of 17 implicit solvers for the proposed formulation using the Kundur's two-area system and a 2,000 bus system.
