How to match the generator set with UPS power supply

Number of views:73

When selecting a generator set, it is not only necessary to consider the power matching, but also to have a deep understanding of the excitation type of the generator, which is beneficial for the normal operation of the UPS power supply.

1. The generator relies on the control of a voltage regulator to output voltage. The voltage regulator detects the voltage of the three-phase output and compares the average value with the required voltage value.

2. UPS power system engineers design input filters and apply them to UPS systems. When using UPS power supply, it can also control current harmonics. These filters play an important role in the compatibility between UPS and generator sets.

3. The monitoring system for the pan geographic UPS power supply room consists of three parts: front-end equipment, user/server APP, and PC large screen terminal. Users can log in through the user app/PC and view the real-time operation status and related parameters of UPS equipment. They can also visually monitor the operation status and related data of the system on the large screen of the mobile phone. When there is an exception, alarm information can be received synchronously.

4. When the Ohmic value of the generator inductance and the Ohmic value of the input filter capacitance are close to each other, and the resistance value of the system is small, vibration will occur, and the voltage will exceed the rated value of the power system.

5. When the UPS power supply and electrical system are under light load, the impact of current harmonics is minimal. But the operating parameters, especially the input power factor, are crucial for the compatibility between the UPS and the generator when the UPS is unloaded.

The generator needs to adapt to the non-linear load characteristics of UPS, so that it can continue to ensure stable power supply from UPS to the load even in the absence of mains power.
