摘要:本文从220KV配电网出发，根据潮流计算是电力系统中重要的分析计算为基础，其最基本的任务是根据给定的电网的参数与结构，和负荷等元件的运行条件，来确定电力系统中各部分的稳态运行状态参数的计算。

　　从220KV配电网实际出发，对3组电站的原始资料的进行整理，通过实际的潮流计算分析出系统中的各个元件系统中所有母线的电压是否在允许的范围以内，系统中各种元件是否会出现过负荷、各节点电压是否满足要求、功率分配和分布是否合理以及功率损耗等，同时引入matlab对潮流计算的高效率性能与易修改性，在节约了大量笔算的时间的情况下再次计算，实现物理算法与mat lab程序算法的对比。

ABSTRACT:From 110KV distribution network, the calculation is based on the trend of power system analysis calculation based, its most basic task is running conditions in accordance with the given parameters and structure of the grid, and the load element, to identify the various parts of the electric power system, the calculation of the steady-state operating condition parameters.

　　　From 110KV distribution network reality, to collate the raw data of the three power station, less than the actual trend analysis of the various components of the system in the system all bus voltage is within the allowable range of, the various components in the system will appear overload voltage to meet the requirements of each node, power distribution and distribution is reasonable and the power loss, The same time the introduction of high-efficiency performance the mat lab on the flow calculation and easy to modify, in the case of saving a lot of hand calculation time again calculated to achieve physical algorithms mat lab program algorithm comparison.
