摘要
为了快速直观地掌握电力系统运行发展状态,应用新型的面向对象的电力系统分析和计算程序Power World对电网安全稳定性进行了可视化分析。以IEEE30节点系统为仿真对象,基于Power World对系统进行了N-1故障计算和对各节点进行了QV曲线分析,并对系统从正常运行到发生大面积电压崩溃的整个发展过程实现了动态仿真,通过分析寻找出系统的薄弱环节并提出了电网的改善措施。研究结果表明:性能优越的Power World可为电网稳定性分析提供一个新的思路与方法。
In order to quickly and intuitively grasp the operation state of power system, a new type of object-oriented power system analysis and the calculation program Power World are applied to analyze visually security and stability of grid. With IEEE 30-bus system as the simulation object, based on Power World, N-1 fault calculation and various nodes of the QV curve are analyzed, and a dynamic simulation of the entire developing process of the system from the normal operation to voltage collapse occurred in a large area is conducted. The weak links in the system is found through the analysis,and ultimately measures are put forward to improve the power grid. The study results show that Power World can provide a new way of thinking and methods of analyzing power system stability.
