ASVG非线性控制及其对电压稳定性改善的研究

VOLTAGE STABILITY IMPROVEMENT USING ASVG NONLINEAR CONTROL

首先建立了新型静止无功发生器（ＡＳＶＧ）控制系统的数学模型，应用零动态设计方法，提出了ＡＳＶＧ的非线性控制规律，并应用于改善无功电压稳定性的仿真研究。结果表明，ＡＳＶＧ非线性控制规律可以有效地改善电力系统电压稳定性。

The control system model of Advanced Static Var Generator (ASVG) is developed in this paper. The nonlinear control schemes of ASVG is proposed on the basis of the nonlinear control theory, and the law is also applied in the study of enhancing power system voltage stability. The research results show that the voltage stability can be effectively improved and voltage collapse can be suppressed effeciently with the nonlinear ASVG controller.
