| 中文摘要:在电力系统中，励磁控制系统具有稳定发电机机端电压，分配机组无功和提高电网运行稳定性的重要作用。本设计中，以改进的AVR+PSS方式为控制算法，选取TI公司的TMS320F28335作为核心控制器，首次使用DSP的PWM移相触发和或门逻辑组合方式产生双控制脉冲。在Saber Sketch环境下，使用MAST语言建立基于离散Symbol的单机无穷大仿真平台，验证方案的可行性及控制性能。并制作控制器硬件电路板，通过小机组运行试验测试控制器性能。实验表明，该数字控制器移相触发准确、可靠，所控机组机端电压稳定，具有非常好的应用前景。 |

| Abstract:In the power system, excitation control system plays a very important role in stabilizing generator voltage, distributing reactive power, and improving the power grid operational stability. In this design, based on the AVR&PSS control algorithm, a TMS320F28335 DSP by TI is selected to be the controller core; a combination of PWM phase shift trigger and logic gates is used to generate dual control pulses. And a single-machine infinite system using MAST language based on discrete symbols, is established in the Saber Sketch simulation platform. The results of the simulation verify the feasibility and control performance. Then, the controller designed above is used to control the operation of the small-capacity synchronous generator. The newly designed excitation controller is proved to have accurate phase-shift triggers, high reliability and operational stability, and a wonderful application prospects. |
