摘要
研究同杆并架多回线同时跳闸时的潮流断面控制方法。通过引入多个分布系数,将同杆并架双回线同时跳闸的过程分解为线路相继跳闸的过程,从而得出同杆并架双回线的潮流断面控制方法,并将此方法扩展到同杆并架多回线的潮流断面控制。实例应用表明:该控制方法能较好地适应运行方式的变化,可精确地反映潮流的转移特性,适用于实际电网的运行监控与计算分析。
The power flow section control method for simultaneous tripping of multiple-circuit transmission lines on same tower is studied.by introducing several distribution coefficients, the simultaneous tripping process of multiple-circuit transmission lines on same tower is divided into the successive tripping process of lines, and thus the power flow section control method of double-circuit transmission lines on same tower is obtained and the method is extended to the power flow section control method of multiple-circuit transmission lines on same tower. Practical applications show that the control method can better adapt to changes of operation mode and accurately reflect transfer characteristics of power flow and is suitable to operation monitoring and calculation analysis of actual power grid.
