| 摘 要： | 移植无换向器同步电机的变速理论,以电枢电流有效值为时间变量,建立水轮发电机电气制动的二维向最数学模型,根据李雅普诺夫函数法计算使制动时间最短的附加电阻最佳值;然后采用能量法计算该阻值下的制动时间;最后以官厅电站一号机组为例,说明理论计算与实测结果相符.

| Abstract: | This paper established 2-d mathmatical model for hdyrogenerator electric braking according to transplantation of variable-speed theory of non-commutator synchronous generator and calculated the optimum value of additional resistance to get the minimum braking time by means of Leapunov's function. Then the optimum braking time value of additional resistance is calculated. As an example, studied for the first unit at Guanting water Power Station shows that the theory calculation is coincident with the practical measurement result. |
