高性能PCC励磁调节器实现方案

摘要

A scheme of excitation controller based on PCC of x20 serials is introduced. CP1486 module is adopted as CPU, which is able to complete PID+PSS2B in time. DS4389 module is adopted to measure period and generate flashing pulses. AI2636 module is adopted to perform AD conversion in fixed frequency, which is combined with the algorithm of interpolation to trace frequency of input signal. Thus Fourier equations can be used. All the functions on real time control have been verified.%　　本文介绍了一种基于x20系列高性能PCC模块的励磁调节器实现方案。励磁调节器的控制通道使用CP1486模块作为CPU，可以满足PID+PSS2B控制运算的要求，使用DS4389模块实现了测频测相和脉冲生成，使用高速定频采样的AI2636模块结合插值算法实现了跟踪频率的交流采样功能。最后通过模拟测试验证了方案的可行性。
