Avr control on generators generator#

The power supply of generator to electric equipment and charging to battery both require its voltage to be stable, so it is necessary to adjust the output voltage of generator if the voltage is kept at a certain value basically.Ī synchronous generator regulator that maintains the synchronous generator voltage at a predetermined value or changes the terminal voltage as planned. Since the transmission ratio of generator to engine is fixed, the speed of generator will change with the change of engine speed. At the same time, it also prevents the generator voltage from being too low, resulting in malfunctioning of electrical equipment and insufficient battery charge.

Its function is to automatically control the generator voltage and keep it constant when the rotating speed of the generator changes, so as to prevent the generator voltage from being too high to burn out the electrical equipment and cause the battery to overcharge. The voltage regulator is an adjustment device that controls the generator output voltage within a specified range. In general, the AC automatic voltage regulator (AVR) is a device designed to regulate voltage automatically – that is, to take a fluctuating voltage level and turn it into a constant voltage level. Power conditioners are typically used in low voltage (<600V) applications and sizes below 2,000KVA. The typical power conditioner is an automatic voltage regulator combined with one or more other power-quality capabilities, such as:Ģ) Short circuit protection (circuit breaker) Generator voltage regulator can be used for ordinary 60/50Hz as well as medium frequency 400Hz single or parallel generators.Īn AVR is at the heart of devices often called power conditioners or power stabilizers. Voltage regulator realizes the automatic regulation of generator output voltage by controlling the excitation current of generator AC exciter.

Voltage regulator (referred to as AVR) is designed for AC brushless generators with fundamental wave, harmonic compound excitation or permanent magnet generator excitation (PMG system). AVR (Automatic voltage regulator) is an instrument that adjusts voltage by means of automatic control device.
