摘要
随着电力系统的迅猛发展,电力系统的安全稳定问题变得日益突出。寻找一种快速、可靠的电力系统静态电压稳定性分析方法十分重要。本文提出了一种Hamiltonian矩阵辛约化的电力系统节点静态电压稳定裕度计算方法,并结合IEEE 33节点的配电网系统进行仿真计算。通过比较辛约化方法与最小特征值分析方法的计算结果,初步验证辛约化方法具有较高的可靠性,因此比较适合电力系统节点电压稳定性分析及相似问题的计算。
With the rapid development of the power system,power system stability and security problem has become increasingly prominent.Looking for a fast and reliable power system static voltage stability analysis method is very important.This paper proposes a calculation method of Hamiltonian matrix symplectic reduction of power system voltage stability margin,and uses the IEEE 33-node distribution network system for simulation.By comparing the calculation results of symplectic reduction method with the results of existing eigenvalue analysis method,it preliminarily proves that the Hamiltonian matrix symplectic reduction method is more reliable.therefore the new method is more suitable for the node voltage stability of power system analysis and the calculation of similar problems.
