摘要
针对电力系统常规潮流计算中变量越界的自动调整问题,从非线性代数方程组求解的角度,通过引入扩展参数,提出了统一的理论基础。以PQ节点V越界的自动调整问题为例,分析了所提理论基础的正确性。最后,以IEEE5、IEEE30、IEEE118节点标准测试系统为例进行了仿真说明。该理论对深入研究电力系统运行控制的特点,具有一定的指导意义。
To the problem of variables violation automation adjustments in conventional power flow calculation of electric power system, from the solution of nonlinear algebraic equations, this paper proposes its fundamental theory by introducing expanded parameter. Take for voltage violation＇s automation adjustments of PQ bus as an example, analysis the proposed fundamental theory is correct, result analysis of IEEE 5-bus, IEEE 30-bus, and IEEE 118-bus standard test systems, has shown it＇s correctness. The fundamental theory has the certain leading meaning for deep studying the characteristic of operation and control of practical power system.
