摘要

潮流计算是研究电力系统分析的一项重要分析功能,它可以确定电力系统的运行方式;检查系统中各元件是否过压或过载;为电力系统的继电保护的整定提供依据;为电力系统的稳定计算提供初值。潮流计算可通过手工方式计算或计算机通过软件计算。计算机计算相对手工计算更精确、更迅速,但物理概念不如前者明显。首先通过对一般的牛顿—拉夫逊法的分析,解出有有功功率和无功功率组成的功率平衡方程组。之后得到雅克比矩阵,反复迭代求解。
        Power flow calculation is an important analysis function for power system analysis, which is used for safety analysis, relay protection identification and fault calculation. It can determine the operation mode of the power system, check whether the components in the system are over-voltage or overload and provide the basis for the setting of the relay protection of the power system, and provide the initial value for the stable calculation of the power system. Power flow calculations can be done manually or by computer using software. Computer computing is more accurate and faster than manual calculations, but the physical concept is not as obvious as the former. Firstly, through the analysis of the general Newton-Raphson method, the Newton iteration method is used to solve the power balance equations with active power and reactive power. Then get the Jacobi matrix and iterate iteratively.
