线路输送功率与电网结构机理分析

现有的潮流算法或是应用潮流算法来解决电力市场中的潮流分布都没能把线路潮流与最基本的网络结构建立起直接的显式关系。利用电路的基本理论，从电流、电压在电网络中的分布机理角度，推导出了线路输送功率与关联矩阵的函数关系，并通过具体算例验证了所提方法的正确性。由于关联矩阵反映了网络的拓扑结构，故线路输送功率与网络结构密切相关。所以改变网络的拓扑结构就可以改变线路的潮流分布，这为从网络结构上消除线路阻塞提供了理论依据。

Mechanism Analysis on Transmission Power and Network Structure

The present power flow algorithms or the applied power flow algorithms which are used to solve the allocation of the power market cannot set up the direct apparent rela- tionship with the basic network structure. The paper deducts the function between transmission power and incident matrix from the angle of current and voltage distribution in electric network, using the classical circuit theory, and validates the correctness of this method by embodied example. Because incident matrix re- flects the topology structure of network, transmission power has a relationship with network structure. Therefore, changing the topology structure of network can change the distribution of power flow, which lays a solid theory foundation eliminating transmission congestion from the angle of network structure.
