摘要
无功功率是电力系统的重要参数,研制出快速、灵活,能在正负两个方向调节无功的装置,对保证供电质量有很大意义.新型静止无功发生器(ASVG)是柔性交流输电技术(FACTS)的核心装置,可有效防止大型电网在无功不足状态下,因电压不稳造成的电网崩溃.本文分析了ASVG的结构及其原理,并进行了仿真,证明ASVG在稳定负荷电压和调节无功方面具有灵活、快速等特点,有广阔的发展和应用前途.
Since reactive power is an important parameter of the power system, a kind of fast and flexible equipment which can compensate reactive power instantly is of great significance to voltage stabilization. The Advanced static VAR Generator (ASVG) is the core equipment of the Flexible AC transform system technology. ASVG is effective in perverting the power system collapse which is caused by the voltage oscillation when the power system is lack of reactive power. The structure of ASVG is proposed here. It analyzed the principle of the ASVG. It proves that ASVG is instantaneous and fast in steadying the load voltage and demodulating reactive power compensation, and prospective to be developed and applied.
