【摘要】：为了分别从电网拓扑结构以及电网运行要素角度出发,对电网输电能力的影响因素进行较为全面地梳理。首先,在将实际电网错综复杂的拓扑结构抽象为二维加权图的基础上,又对其进行了二维平面垂直坐标轴方向上的归一化处理,基于电路相关理论推导,证明了增加直连线路对于输电能力的提高效果要优于增加间接连接线路,并经过仿真计算进行了验证;其次,基于多对象耦合多影响因素问题梳理降阶的思路,将输电网按其结构本质分成了点对网型和网对网型两种输电结构,并根据各类网架结构的特点分类研究。结果表明:送受端电网侧、输电通道以及网内电源侧因素皆为影响电网输电能力的因素,并经过大量的实际电网仿真算例进行了验证。这为提高电网的输电能力提供了理论支撑和具体策略。
[Abstract]:In order to separate the power grid from the angle of the power network topology and the operation elements of the power grid, the influence factors of the power transmission capacity are combed in a more comprehensive way. First, on the basis of the abstract topology of the actual power grid as a two-dimensional weighted graph, the two dimensional vertical coordinate axis direction is normalized. Based on the theoretical deduction of the circuit, it is proved that the increase of the power transmission capacity of the direct connection line is better than the increase of the indirect connection line, and is verified by the simulation calculation. Secondly, based on the multi influence factors of multi object coupling, the idea of reducing the order is combed, and the transmission network is divided into the network type and the net type network type two according to its structure essence. The transmission structure is classified and classified according to the characteristics of various grid structures. The results show that the factors that affect the power transmission capacity of the power grid are all factors that affect the power transmission capacity of the power grid, and the power transmission channel and the power side factors in the network are verified. This provides a theoretical support and concrete support to improve the power transmission capacity of the power grid. Strategy.
