基于DSP的一体化水轮发电机控制系统设计与实现

电能质量主要有三个指标,即电压频率、电压幅值、相位关系。然而实际水力发电中所产生的电能是不理想的。如果把发电机组和智能控制看作整体来设计,通过水轮机光电码盘传感器,把速度采集后传送到DSP芯片,与设定值进行比较,进行PID调节,输出对调速器进行控制;同时采集发电机输出端的电压与标准值进行比较,通过电压互感器采集数据进行PID调节,计算输出电压来控制励磁电流。从而实现机组优化控制,得到较为优质的电能对社会具有重要意义。

Design and Implementation of the Integration of Hydraulic Generator Based on DSP Control System

There are three main indexes for power quality, which are the voltage frequency, the voltage amplitude and the phase relationship. However, the power actually generated in hydropower is not ideal. If taking the generator set and intelligent control as a whole for designing, the speed collected through the turbine light code disc sensor is sent to the DSP chip and compared with the set value to makes the PID adjustment. The output controls the speed governor. At the same time, the voltage in generator end is collected to be compared with the standard value, and the PID adjustment is made through the acquisition data of voltage transformer so as to cal- culate the output voltage to control the exciting current.
