【摘要】 提出了一种用于大型电力系统联网规划的分割算法．基本思路是先将大型电力系统分割成若干子系统，对各子系统分别进行计算，然后求解仅由联络线及分割子系统数确定的联络网络方程组，确定各子系统参考母线间的相位差以及各联络线上的潮流，进而可以获得整个电力系统各节点电压相位角和直流潮流分布．更多还原

【Abstract】 A piecewise algorithm for the interconnection planning of power systems is presented. The basic idea is to split apart a large power system into a number of subsystems or pieces, and each piece is calculated independently. Simultaneous circuit equations, the number of which is only defined by the number of tie lines and subsystems, are then solved to obtain the voltage angle differences among the reference buses of the subsystems and power nows on tie lines. The voltage angle and the power flow of the complete system can easily be obtained.更多还原
