Vref：发电机自动给定电压，单位V。因为调节器自动运行方式是按发电机电压反馈闭环运行，因此此处以发电机PT电压值作为基准。Vref: Generator automatism reference voltage, unit is V. Because regulator automatism run mode is running according to generator voltage feedback closed loop, here make generator PT voltage value as reference value.

由于CT、PT存在的一定的角度差，调节器采样得到的有功无功值与实际的有功无功值有一定的偏差，因此采样值与实际值间还有一个角度误差补偿，有关该误差补偿详见第5.3.2.1.2章节。Because CT and PT exist stated angle error, active power and reactive power value gained by regulator sampling and actual value exist error, there is a angle error compensation between samplinging value and actual value, about the error compensation details to see chapter 5.3.2.1.2 .
