Abstract

Due to rapid developments in high-power semiconductor switches and their control structures, improvement of stability of power system network turns out to be possible with FACTS controllers of different combinations. Unified Power Flow Controller (UPFC) is one of the most commonly used FACTS device. In conventional UPFC, two voltage source inverters(VSI), one is for Static Synchronous Compensator known as STATCOM and another one for Static Synchronous Series Compensator known as SSSC, functioned from a common DC link provided by a DC storage capacitor. To analyze the performance of UPFC in Sliding Mode Control (SMC), it is simulated in MATLAB. It has been observed that the simulation explains P and Q power flow control. SMC is a non-linear control intended to consider the dynamics of the converter for non-linear on-off behavior of the converter. In general, the fuzzy logic encodes human reasoning into a program. Fuzzy Logic Control (FLC) when used as a controlling method for UPFC has better stability, small overshoot and fast response.

基于SMC和FLC的统一潮流调节器的实现，以改善功率因数

随着大功率半导体开关及其控制结构的迅速发展，采用不同组合的FACTS控制器可以提高电网的稳定性。统一潮流控制器(UPFC)是一种最常用的FACTS设备。在传统的UPFC中，两个电压源逆变器(VSI)，一个用于静态同步补偿器，称为STATCOM，另一个用于静态同步串联补偿器，称为SSSC，由直流存储电容提供的公共直流链路起作用。为了分析UPFC在滑模控制(SMC)中的性能，在MATLAB中对其进行了仿真。结果表明，该仿真解释了P和Q功率流控制。SMC是一种非线性控制，旨在考虑变换器的非线性通断行为的动力学。一般来说，模糊逻辑将人类的推理编码到程序中。模糊逻辑控制(FLC)作为UPFC的控制方法，具有稳定性好、超调量小、响应快等优点。
