【摘要】 本文分析了电力网负荷节点暂冬电压崩溃的引发过程与抑制方法。为满足"规定的事故后母线电压水平",必须在适当地点设置"事故紧急备用无功容量",为此提出的抑制策略包括控制系统模型、SVC与SVG的比较以及用模态分析方法研究这些高速调节装置的合理安装地点问题。更多还原

【Abstract】 The happening of transient voltage collapse and its preventive mechanism of load bus in power network is analyzed. One should install the faulted emergency reserve var compensation capacities in the most effective site for satisfing the specified past fault bus voltage level. The restraining methodologies of transient voltage collapse are presented. The system model of control actions for research, the characteristic comparation of SVC and SVG and how to indentify the most effective site to install these apparatus are included.更多还原
