The role of the regulator is to ensure that the generator output voltage to maintain a constant energy, protect the safe operation of equipment.
调节器的作用就是保证发电机在输出电能的电压能够保持恒定，保护设备安全运行。

An automatic voltageregulator ensured a constant output from the generator.
一个自动电压调节器保证了发电机电流输出的稳定。

Voltage control the voltage control is a rheostat that sets the operating point of the voltageregulator and therefore controls the output voltage of the generator set, within its design limits.
