摘要
湖南电网现有的网架结构和电源分布导致湘中地区的暂态电压稳定水平较低,严重威胁了系统的安全稳定运行。针对湘中地区的网络特点,提出通过打开220kV白马垅变电站的母联开关来提高湘中暂态电压稳定水平的方式,研究表明在这种运行方式下,湘中地区的暂态稳定水平得到了明显地提高。
The current network structure and the distributions of power supply lead to the comparative low level of the transient voltage stability in central Hunan grid. In this paper,a typical operation mode is brought out in order to improve the situation. The computing results show that this operation mode is effective.
