Is it really feasible to match a generator set with a UPS power supply?
When selecting a generator set, it is not only necessary to consider the power matching, but also to have an in-depth understanding of the excitation type of the generator, which is conducive to 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 three-phase output voltage and compares the average value with the required voltage value.
2, UPS power system engineers design input filters and apply them to UPS. When UPS power is used, it can also control current harmonics. These filters play an important role in the compatibility of UPS and generator sets.
3. The monitoring system of the pan-geographic UPS power supply room is composed of three parts: front-end equipment, client/server APP, and PC large screen. The user can view the operating status and related parameters of the UPS equipment in real time after logging in through the user terminal APP/PC, and can also directly view the operating status and related data of the nursing system on the big screen of the mobile phone. When abnormal, the alarm information can be received synchronously.
4. When the ohmic value of the generator inductance and the ohmic value of the input filter's capacitive reactance are close to each other, and the resistance of the system is small, vibration will occur , 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 current harmonics have little effect. However, the operating parameters when the UPS is unloaded, especially the input power factor, are critical to the compatibility of the UPS and the generator.
The generator needs to adapt to the characteristics of the UPS's non-linear load, so that it can continue to ensure that the UPS power supply provides a stable power supply to the load when there is no mains power.
