Abstract

This work deals with power system stabilization through a flexible transmission line (FACTS). Series compensation is introduced by a controlled switching scheme that changes the transmission line reactance. Switching is implemented according to variable structure control concepts in order to establish a sliding mode operation where oscillations die out very fast. A power system consisting of a synchronous generator, a line reactance with series compensation and an infinite bus is used as a case study. For this basic power system control strategies are shown to pursue: a) sliding mode operation; b) asymptotic stability; or c) asymptotic stability with sliding mode operation. The last strategy assures asymptotic stability for large oscillations and afterwards a fast convergence towards a stable equilibrium state. Simulation tests are then performed for the basic power system, first, for an initial condition and then under a disturbance. The dynamics of a reduced model of a real power system is also studied under a disturbance. The combined strategy, asymptotic stability with sliding mode, shows to be adequate for power system stabilization

用变结构控制进行串联补偿的电力系统镇定

本文研究了通过柔性输电线路实现电力系统稳定的问题。串联补偿是通过改变传输线电抗的控制开关方案引入的。切换是根据变结构控制的概念来实现的，目的是为了建立一种快速消除振荡的滑模操作。以一个由同步发电机、带串联补偿的线路电抗和无限母线组成的电力系统为例进行了研究。对于这一基本电力系统的控制策略显示为:a)滑模运行;B)渐近稳定性;或c)滑模操作的渐近稳定性。最后一种策略保证了大振荡的渐近稳定性，然后快速收敛到稳定的平衡状态。然后对基本电力系统进行了模拟试验，首先进行了初始条件下的模拟试验，然后进行了扰动下的模拟试验。研究了实际电力系统的简化模型在扰动作用下的动力学特性。渐近稳定与滑模的组合策略可以很好地实现电力系统的稳定
