This paper also considers the estimation problems based on the different Cartesian coordinates. 本文还考虑了各传感器分布在不同地理位置时的状态估计问题。
Linear measurement equation and linear static state estimation algorithm based right-angle coordinate are proposed when only PMU measurements are used. 在完全使用相量量测的情况下,提出了基于直角坐标系的实数形式的电力系统线性量测方程,和相应的线性静态状态估计算法。
