临界切除时间的确定方法及装置
摘要：
本发明公开了一种临界切除时间的确定方法及装置，首先通过直接法计算确定临界切除时间初值tcr，然后根据所述临界切除时间初值tcr和时域仿真系统误差error确定搜索范围，在所述搜索范围内，采用二分法搜索并确定临界切除时间CCT。所述临界切除时间的确定方法及装置，以直接法的计算结果为初值，基于该初值，用时域仿真法进行精确搜索，在提升计算速度的同时，保证了临界切除时间结果的准确性。
摘要（英）：

The invention discloses a determination method and device for critical clearing time. According to the method, first, a critical clearing time initial value tcr is calculated and determined through a direct method, second, a search range is determined according to the critical clearing time initial value tcr and a time domain simulation system error; and last, a dichotomy method is adopted to search for and determine the critical clearing time CCT within the search range. According to the determination method and device for the critical clearing time, a calculation result of the direct method is used as the initial value, a time domain simulation method is adopted to perform precise search based on the initial value, and therefore the accuracy of a critical clearing time result is guaranteed while calculation speed is increased.
