项目摘要

Transient phenomena cased by faults of power systems are very complex. In order to assess accurately them, simulation methods must be used. But, they have the following problems.(1)In order to grasp the whole characteristic of transient phenomena, a great number of simulation cases must be carried out(2)It is difficult to gain the whole prospects of assessment based on results of individual simulation cases.(3)When simulation conditions change, simulation must be carried out from the beginning.This research investigates the method to overcome the above problems. At first, transient stability which is the most important characteristic to assess in power systems is adopted as the object one and critical fault clearing time functions are newly defined by taking notice of the fact that transient stability is mainly controlled by fault clearing time and load Next, the method to assess transient stability using critical fault clearing time functions has been developed. Finally, it has been applied to the transient stability assessment of faults in model power systems. Results of application have been clarified the following facts.(1)This method can accurately and efficiently assess power system transient stability.(2)This method can accurately and efficiently assess the effects of design factors (for examples, system constitutions, equipments, control and protection systems ) on transient stability.(3)This method can be used in the practical planning of power systems, for it has the above characteristics.

电力系统故障引起的暂态现象十分复杂。为了准确地评估它们，必须使用模拟方法。但是，它们存在以下问题。(1)In为了把握瞬态现象的整体特性，必须进行大量的仿真实例。（2）单靠单个仿真实例的结果很难得到评估的整体前景。（3）当模拟条件发生变化时，必须从头开始进行模拟，本研究探讨了克服上述问题的方法。首先，以电力系统最重要的暂态稳定特性为研究对象，考虑到暂态稳定主要受故障切除时间和负荷的控制，定义了临界故障切除时间函数。其次，提出了利用临界故障切除时间函数进行暂态稳定评估的方法。最后，将其应用于模型电力系统故障的暂态稳定评估。应用结果表明：（1）该方法能够准确、高效地评估电力系统暂态稳定性。（2）该方法能准确、有效地评估系统结构、设备、控制和保护等设计因素对暂态稳定的影响。（3）该方法具有上述特点，可用于电力系统的实际规划。
