摘　　要：换流阀的工作状态与其温度密切相关,通过对冷却系统中阀厅温度的准确建模,能够推断出换流阀的工作状况。由于实际阀厅温度包含周期成分与非周期成分,提出一种将傅里叶变换、自回归模型和广义ARCH模型等方法集成的动态数据建模方法。通过采集现场数据进行实例建模与模型仿真,结果表明,该模型具有较好的一致性和准确性,可以为大功率电力电子设备研究提供一种新的数据建模方法。Converter valve＇s working condition is highly related with its temperature. So by modeling the valve hall temperature of valve cooling system, converter valve＇s working condition can be obtained. As the valve hall temperature contains both the periodical and non-periodical component, an integrated modeling method which consists of Fourier Transform, Auto-Regressive model and Generalized ARCH model was proposed. After evaluating with field data and model simulation, it is shown that the model has good consistency and accuracy, so it provides a novel dynamic data modeling method for high power electrical device.
