摘要
在满足区域间联络线族静态安全N-1约束的前提下,计及典型负荷模式和发电最大、最小模式,对大型互联电网的区域间极限传输容量(TTC)进行了分析,推导出了TTC计算的简化数学模型,说明了电网运行方式变化对TTC具有显著影响.依据系统实时运行数据以及预定的发电调整模式,以实际系统进行计算分析,结果表明本方法对提高区域间允许传输容量具有重要意义.
The total transfer capability (TTC) over the interconnected transmission network was analyzed by taking typical load mode and most generation mode and least generation mode into account with the N-1 steady state security constraints of tie line group. A simple mathematic model was introduced and the significant influence on TTC was indicated. The case study was made at a practical system according to the real-time operation data and scheduled generation mode, and it is proved that the method is very effecti...
