| 摘要: |
| 提出了一种经济型小水电励磁装置。通过嵌入微控制器dsPIC30F6014（简称F6014）作为该励磁装置调节器的核心，通过F6014的A ／ D转换接口和数字接口主要完成数据计算、逻辑控制等功能；通过F6014的定时器，输入捕捉和输出比较模块密切配合生成触发脉冲控制三相整流桥导通整流；并根据机组特点配置线性或非线性电阻灭磁。而且F6014自带CAN模块和SPI模块，使其人机交互、机机通信更加便利。在软件方面，利用提供的集成开发环境MPLAB IDE，采用C语言与汇编语言相结合的方式编写程序，使程序更加灵活可靠。短路实验、空载实验和负载实验数据和目前在现场的反馈情况，证明该励磁装置性能优越。 |

| Abstract: |
| An economical excitation device is proposed for small hydropower，which takes the embedded microcontroller dsPIC30F6014 as the core of controller. The data computation and logic control are implemented by its A ／ D conversion ports and digital ports；the trigger pulses are formed by the close cooperation of its timer，input capture and output comparison modules to control the three-phase rectifier；the linear or nonlinear resistance for de-excitation is configured according to the characteristics of unit. Its CAN and SPI modules make human-machine interaction and machine-machine communication more convenient. The combined programming with C and assemble language in the integrated development environment MPLAB IDE makes the programs more flexible and reliable. The short-circuit test，test without load，test with load and site operation prove the superior performance of the designed excitation device. |
