| Abstract: |
| An inexpensive，multi-channel model identification apparatus with low power consumption is designed for the excitation system of synchronous generator，which consists of the data acquisition card and the model identification software for superordinate computer. The data acquisition card takes MSP430F2274 as its core and realizes the functions of operating parameter setting，multi-channel synchronous acquisition，data storage and uploading under the control of superordinate computer. The model identification software developed with Matlab has the functions of data collection，data processing，model identification and model validation，in which sixteen excitation system models are embedded：DC exciter excitation systems，AC exciter excitation systems and static excitation systems. Experimental results show that the designed apparatus meets the demands of synchronous generator excitation system for model identification. |
