The main object of this research is to develop,(1)a method for fast transient stability assessment and a preventive control method being able to take into account transient stability, (2) a security index for automatic contingency selection. Our research results are summarized as follows.(1) Fast transient security Assessment and preventive controlA fast transient stability simulation method based onaa linearized load flow model was developed. The computing speed of this method is about 1100times as fast as that of the conventional method.A pattern recognition method for transient stability assessmentaand preventive control was satisfactorily developed.(2) Security indexA new security index for contingency selection was defined by the vector norm of overloading and out-of-limit voltages. Subsequently, it makes possible the contingency analysis considering both line overloading and bus voltage limit violation and the ranking of contengency to be analized. Appling this method to the IEEE 30 bus system, the effectiveness of the method was confirmed.(3) OthersIn order to inspect the inter-action between dynamic security preventive control and real power control,an optimal scheduling method for the daily power system

本研究的主要目的是开发（1）一种快速暂态稳定性评估方法和一种能够考虑暂态稳定性的预防控制方法，（2）自动应急选择的安全指标。我们的研究成果如下：(1)快速暂态安全评估与预防控制提出了一种基于线性化潮流模型的快速暂态稳定仿真方法。该方法的计算速度是传统方法的1100倍左右，较好地开发了一种用于暂态稳定评估和预防控制的模式识别方法。(2)安全指标通过过载和越限电压的向量范数定义了一种新的应急选择安全指标。随后，它使得考虑线路过载和母线电压限制违规的应急分析以及待分析的应急排序成为可能。将该方法应用于IEEE 30总线系统，验证了该方法的有效性。(3)其他为了考察动态安全预防控制与有功功率控制之间的相互作用，提出了一种日常电力系统的优化调度方法。
