摘要
提高交流输电系统输电能力是电力系统的重要发展方向。UPFC是FACTS中的典型装置,能有效控制交流电力系统参数。基于功率注入法,提出了一种考虑UPFC的输电系统潮流控制方法,讨论了UPFC的稳定控制域。该方法在不改变传统雅可比矩阵结构的同时,修正雅可比矩阵相应元素,联立潮流控制目标,利用传统潮流方法求解支路潮流。仿真结果表明在稳态条件下UPFC能在较大范围内灵活控制支路潮流,验证了本算法的有效性。
Enhancing AC power transmission capacity is an important development for the power system. UPFC is a typical device in FACTS that can effectively control AC power system parameter. UPFC- a power flow control method for power transmission system that based on the power-injected method is proposed in this paper, and the stability control field of which is also discussed, This method can modify Jacobian matrix, set up power flow target without changing traditional Jacobian matrix structure, and solve branch power flow by traditional method. Simulations show that under static condition, UPFC can flexibly control branch power flow on a large scale, and the validity of this method has been proved.
