【摘要】：针对变压器参数辨识算法在系统稳态运行时变压器绕组参数具有不可辨识性的特殊问题,本文提出了全新的参数辨识算法模型和基于自相关函数统计量的参数辨识结果判别标准。并使用EMTP仿真工具,依据动模实验室特高压输电系统,搭建了特高压输电系统仿真模型,分别仿真了特高压变压器空载投入、区外故障、区内故障和正常运行时的各种运行状态,验证了在各种工况下,基于新模型的参数辨识算法都能够精确辨识出变压器绕组参数的真实值。
[Abstract]:In order to solve the special problem that transformer winding parameters are not identifiable when the transformer parameter identification algorithm is in steady state operation of the system,In this paper, a new parameter identification algorithm model and a criterion of parameter identification results based on autocorrelation function statistics are proposed.The simulation model of UHV transmission system is set up according to the UHV transmission system in dynamic model laboratory by using EMTP simulation tool. The UHV transformer is simulated respectively in no-load and out-of-area faults.It is verified that the parameter identification algorithm based on the new model can accurately identify the true value of transformer winding parameters under various operating conditions.
