摘要
本文提出一种快速分解状态检测方法适应于电力配电网,首先通过迭代求解出所有节点的电压幅值的平方,然后解出所有支路两侧的相角差值,收敛之后求出电压复相量。通过分析证明相较于高阻抗比的配电网具有很好的适应性和计算效率,具有良好的应用前景。
This paper presents a fast decomposition state detection method for distribution network,first,the square of the voltage amplitude of all nodes and the phase angle difference of all branches are solved iteratively,after convergence,the voltage complex phasor can be solved.This method does not need the precondition of high impedance ratio in the modeling process,and can use current amplitude measurement.The example analysis shows that this method has good adaptability and calculation efficiency for distribution networks with high impedance ratio,and possesses a good applied perspective.
