为了提高电力系统潮流解算效率,给出了基于广义Tellegen定理的潮流快速算法。该方法以电力网络节点电压方程为基础,建立了基于广义Tellegen定理的伴随网络方程,并根据广义Tellegen定理差形式,形成了简捷的潮流迭代方程。在迭代求解过程中,简化了求解过程,缩短了计算时间;同时,在计算中分别给出了PQ节点、PV节点及平衡节点的处理方法和计算公式。仿真结果表明,本文算法与保留非线性电流注入型算法相比,在保持计算精度和收敛性不变的情况下,提高了潮流计算速度。

In order to improve the efficiency of the power flow calculation, the fast power flow calculation based on General Tellegen’s theorem was proposed. The method provides the adjoint network equation based on the General Tellegen’s theorem according to nodes voltage equation in power network, and the simple and direct power flow iterative equation was formed according to different forms of General Tellegen’s theorem, which simplified the solving process and shortened the computation time in iteration solving process. At the same time the method provides the handing method and the computation formulas of the PQ nodes, PV nodes and the balance node. The simulation results show that compared with the current-influx model retaining-nonlinearity power flow calculation, in the case of keeping the calculation accuracy and the same convergence, the speed of this method’s calculation is improved.
