中文摘要：
针对电力系统复杂网络自身的特点，提出一种基于潮流解和网络拓扑理论的等值方法，并对其进行了理论推导，解决了在电网中相邻两节点处同时进行等值的问题。该方法计及等值节点间的耦合阻抗，同时也适度考虑了系统的动态性能，提高了等值精度。IEEE30母线系统的仿真分析表明，等值前后，系统的静态性能相匹配，动态响应也比较接近，能够满足简化网络以搭建暂态模型的要求。该方法具有较强的适应性和实用性，为实现电网的快速安全稳定评估提供了可行的办法。
英文摘要：
In accordance with the characteristics of complex network in power systems, this paper puts forth an equivalent method based on power flow solution and network topological theory. This method, which can solve the problem of simultaneous equivalent of two adjacent nodes in the power grid, is deduced theoretically. To improve the equivalent accuracy, the coupling impedance between the equivalent nodes is taken into account, and the dynamic performance of system has been considered moderately. Simulation on the IEEE 30-bus system shows that the static performance of the system equivalent by the method proposed is comparable to that of the complete original system, and those dynamic responses are also relatively close. Thus the network can be well simplified so that a suitable transient model can be set up. The proposed method is practical to the network reduction and can lay solid foundation for the assessment of power-grid security and stability.
