摘要现代电力网络面临着不能满足长距离、大功率等输电问题，而 FACTS技术是解决这些问题的有效方案。 柔性交流输电技术 （FACTS） 的广泛应用，为电力系统提供了新的一种控制手段。 这些装置不仅提高电力系统的输电能力、改善运行特性、控制运行状态，还给电力系统分析带来了新的挑战。UPFC综合了多种 FACTS 元件的灵活控制手段，能同时或选择地控制线路的基本参数(电压、阻抗、相角)，也可交替地控制线路上的有功和无功潮流。UPFC还可独立地提供可控的并联无功补偿[1]。本论文主要是编写在电力系统网络中加入FACTS元件后的潮流计算程序设计， 了解加入FACTS后对电力网络的影响。UPFC是最典型的元件，可以很好的代表 FACTS 的功能，所以本文以传统的牛顿—拉夫逊迭代法为基础，并根据 UPFC 的性能和对网络数据的影响对其进行修正，而实现对 UPFC的编程。 21143

Title The promgram design of power flow calculation with FACTS devices
Abstract
FACTS technology is an effective solution to the problems that modern electricity
network can not meet the long-range, high-power power transmission problems.
FACTS is widely used, and provides a new means of control for electric power system.
These devices not only improve the transmission capacity of the power system, the
operating characteristics, the operating state, but also has brought new challenges for
power system analysis.
UPFC contains lots of flexible control methods of the FACTS, which can control
three essential parameters (Voltage, Impedance, phase -angle) of the line concurrently
or selectively, and it can also control the active power and reactive power flows of the
line. This thesis is written to program the power system network with FACTS, and
understand the impact on the electricity network after adding FACTS comprehensively.
The most typical device of FACTS is UPFC, which can well represented FACTS’s
functions. In this paper, basing on the traditional Newton - Raphson iterative method,
and in accordance with the performance of UPFC and impact of network data, the
program of UPFC is accomplished.
