柴油发电机组做为备用电机电源或移动电站广泛用于高层建筑、银行、机场和油田等场合。应用中需控制柴油发电机组的转速和电压,使其具有良好的电气性能。采用TMS320F2812DSP捕获单元处理柴油发电机组的磁电式转速传感器信号,实现柴油发电机组转速数字控制器的转速测量功能。经实验测试,该系统设计测速精度较高,有较强的实用性。
- Abstract:
- Diesel generator bank,as standby power or mobile power station is widely used in high rise building,bank,airport and oil field.In application,its speed and voltage needs to be adjusted to ensure good electrical specifications.A speed measurement method used in digital speed controller is presented in this paper by processing signal from magnetoelectric tachometric transducer with capture unit of TMS320F2812DSP.It is proved this system design is an exactitude and feasible method by tests.
