摘要
本文致力于开发一种适用于大型电力系统的静态电压稳定实时快速分析及预防调度软件,结合目前电压稳定分析方法在实际系统中的应用,考虑实时分析的速度与精度要求,使用一种基于灵敏度约束与局部曲线拟合相结合来快速寻找崩溃点的方法与基于优化发电功率分配因子来提高系统负荷裕度的方法,研制开发了一套基于B/S模式的"在线电压稳定快速分析及预防调度"软件.使用该软件对湖南电网静态稳定性进行算例分析,验证该软件能满足在线分析的速度与精度要求.
The thesis commits to develop a type of software applicable for the rapid analyzing and prevention scheduling of static voltage stability in large-scale power system, by bring the application of current voltage stability analyzing method in real system into consideration, reviewing speed and precision requirements for real-time analysis,use the method of anchored on the combination of sensitivity restriction and local curve fitting to detect collapse point rapidly and precisely and the method of grounded on the optimizing of generated power distribution factor to raising system load margin, to researches and develops a set of software serving for online voltage stability rapid analyzing and prevention scheduling. The software is empowered to process an example analysis to the static stability of Hunan Grid, it can meet the speed and accuracy.
