| 摘 要： | 提出采用精度更高、绝对稳定域更大的三步隐式Adams法对现有的阻尼绕组电流计算方法(一阶向前差分法,R-K1)进行改进,并分析了初值设置和采样频率对算法的影响,结果表明改进的方法具有对于同步电机阻尼绕组实际电流的更好的跟踪特性。文中以基于PSCAD的IEEE次同步谐振第一标准模型为例,通过仿真验证与对比分析,体现了采用三步隐式Adams法计算阻尼绕组电流的优越性。

| Abstract: | The three step implicit Adams method which has higher accuracy and lager absolute stability region is proposed to improve now existing damper winding current calculation (one step forward difference method). Also, the effect of initial value setting and sampling frequency to algorithm is analyzed. Results show that improved method has better performance on tracking damper winding current of synchronous generator. By calculating damper current of synchronous generator in IEEE first bench case for SSR in PSCAD with simulation and comparison, advantage of the three step implicit Adams method is testified. |
