摘要
汽轮机组的容量超大型化和参数超临界化的趋势,使得汽轮机及调速系统模型参数的确定对各种热力发电机组的仿真、控制系统的设计及电力系统动态研究具有更加重大意义。由Matlab GUIDE开发平台设计汽轮机及调速系统参数辨识数据处理软件,对原始数据实现图形化截取,并进行小波去噪、数据标幺化、归一化处理,为参数的准确辨识提供基础。软件使用简捷明了,可提高工作效率。对600 MW超超临界机组汽轮机调速系统的试验数据进行处理计算,并用经典与改进模型针对特殊的阶跃响应作出仿真和分析。
Due to the trend of large capacity and super-critical parameter of steam turbine, the determination of parameters for steam turbine and governor system model has great significance to the simulation of thermal generating units, control system design and power system dynamics research. The graphical intercept of original data is achieved by parameter identification and data processing software of turbine speed governing system designed by Matlab Guide development platform. The wavelet denoising, per unit of data, normalization is conducted which contribute to accurate identification of turbine system parameter. S^tware using method is simple and clear which improves work efficiency. The test data of ultra-supereritical unit of 600 MW steam turbine speed control system were processed algorithms, and the specific step response was simulated and analyzed by a classic and improved model.
