摘要
经过系统小信号稳定分析发现 ,河南与湖南电网之间存在弱阻尼的区域振荡模式 ,河南电网还有次弱阻尼的局部振荡模式。位于河南电网的灵宝背靠背直流系统可发挥直流快速调节特性的优势改善交流系统的稳定性 ,其中对交流系统振荡的附加阻尼控制是直流可采用的措施之一。
By analysis of power system linear stability(small signal), it is discovered that there is a poor damping in region eigenvalue mode between Henan grid and Hunan grid as well as a sub-poor damping of local eigenvalue mode in Henan grid. Lingbao back to back DC system located in Henan can improve AC system stability due to its fast regulating characteristics. The additional damping modulation for AC system is one of the solutions carried out by DC method.
