摘要:
      同步发电机组参数的正确性严重影响电力系统仿真及稳定控制结果的有效性,然而励磁和调速系统中大量非连续环节的存在,严重限制了现有在线辨识方法的高效应用。为解决该问题,提出了一种非连续动态同步发电机组的空间正则化参数辨识方法。该方法将不同状态空间下的非连续动态方程转化为统一的等效表达式,并利用简约空间内点算法对含离散化动态方程约束的参数辨识问题进行求解,从而实现参数辨识问题中对非连续动态方程的准确、高效处理。最后,大量的数值试验和实际测试结果验证了所提方法的有效性。
Abstract:
      The validation of synchronous generator parameters critically affects the effectiveness of power system dynamic simulation and stability control results. However, there are a number of discontinuous dynamic components in the excitation and speed governing system, which significantly restrict the effective application of existing online estimation methods. In order to tackle this problem, a space regularization parameter estimation method is proposed for the discontinuous dynamic synchronous generators. This method converts discontinuous dynamic equations of different variable spaces into a unified representation. Then the reduced-space interior point method is applied to the discretized unified dynamic constrained nonlinear programming problem to obtain the estimated parameters and achieve the accurate and efficient handling of discontinuous dynamic equations. Finally, a large amount of numerical experiments and filed tests are demonstrated to verify the effectiveness of the proposed method.
