基于连续潮流算法的可传输容量计算

Continuous Power Flow Method for Available Transfer Capability Computation

对可传输容量进行了分析,探究了基于连续潮流算法的可传输容量计算方法。对正常运行和事故条件下电力系统母线之间、区域之间可传输容量计算进行了探讨和分析。在Matpower平台上编程,并与Matlab和Powerworld接口,实现了可传输容量计算的可视化,并可任意改变系统的运行方式、条件和参数,形成不同的运行状态(基本潮流),从而计算不同运行情况下母线间和区域间可传输容量。算例的仿真结果表明,在Matpower、Matlab和Powerworld 3个平台上,可传输容量计算均具有灵活性、可行性和可视化。

This paper based on continuous power flow method, proposes a method for computing available transfer capability by studying the capacity. In the proposed method, the available transfer capability between buses, zones and areas is studies under any condition of normal or contingent status of power systems. Interfacing Powerworld software, visual computation is accomplished, and interfacing Matlab software, the operation modes, conditions and parameters of the visual power systems in Powerworld software are changed according to the needs of computating available transfercapability between buses and zones in any cases. An studying example of simulation is given to illustrate the flexibility feasibility and visualization of the proposed method in the three platforms Matpower, Matlab and powerworld.
