梯级电站等微增率方程组的分解协调算法

本文中，对电力系统经济调度中梯级电站的水系耦合，提出一种等微增率方程中也计及水系耦合影响，可利用稀疏矩阵技巧、又具有分解协调作用的算法，并提出了梯级电站经济运行的算例。算例计算结果表明，本文算法的收敛性，计算速度和计算结果的准确度均令人满意。

DECOMPOSITION AND COORDINATION FOR CASCADE STATIONS EQUAL INCREMENTAL EQUATIONS

In this paper, aiming at the problem of water way coupling of cascade station in power system economic operation,an arithmetic,including water coupling in equal incremental equations,using sparsity matrix technics, and using decomposition coordination, be prsented,an example of cascade stations economic operation be prepared,and result of this example shows that this arithmetic is satisfactory in covergence,computation speed and accuracy.
