摘　　要：直流法潮流在交流潮流模型的基础上根据实际电网特点做出合理假设,在确保较高准确率的情况下大大简化了潮流计算过程。提出了一种基于直流法潮流的快速潮流计算方法,可通过手工计算快速得到计算结果,可应用于电网规划设计、运行方式安排及调度操作等。通过实际电网算例证明,该方法计算简便快速,在对电网进行合理简化的基础上该算法的计算精度一般可达90%以上,完全可以满足工程计算的要求。On the basis of AC power flow model, the DC power flow method makes some rational assumptions according to the characteristics of practical network, thus simplifying enormously the calculation process while making little influence on calculation accuracy. A fast power flow calculation method is presented based on DC power flow meth- od, which can acquire results rapidly by manual calculation and can be used in network planning and design, strate- gy arrangement and equipment operation. The calculation examples in actual network demonstrate that the method is fast and convenient, and the calculation accuracy can reach 90% on the basis of rational simplification of network, which can meet the needs of engineering calculation.
