The difference between UPS power supply, diesel generator and EPS power supply

The basic concept of the difference between the three kinds of backup power sources EPS is an emergency power source. In the event of a power outage, it can continue to supply power to the load to ensure that there is no power outage, thereby maintaining people's lives and the safety of the industry. EPS power supply can be divided into three categories: emergency lighting, power conversion and power conversion. UPS is a kind of uninterruptible power supply. When the main power supply is abnormal or suddenly interrupted, it can continue to supply power to the equipment within a certain period of time to provide users with sufficient operating time. The diesel generator components are mainly diesel generator sets and emergency diesel generator sets. Relevant electrical regulations and national standards stipulate that a certain type of high-rise building should be powered by first load, and emergency diesel generator sets must be used. In our country, EPS is mainly used for fire-fighting loads and some electrical equipment that does not require high power supply quality but must ensure continuous power supply, and only focuses on the function of continuous power supply. When EPS is used for fire-fighting loads, its product technology has been certified by the Ministry of Public Security for fire protection. UPS power supplies are commonly used in computers and digital information systems. Regarding loads with high power quality, it is important to emphasize the switching time, output voltage, frequency stability, purity of the output waveform, and the absence of various interferences of the inverter. Diesel generators are used in places that are not connected to the grid, which may be an emergency power source in the event of a grid failure, but also for more complex applications such as peak tripping, grid support, and grid output. Important communication equipment, nuclear power plants, hospitals, industrial plants, hotels and office buildings are also equipped with emergency diesel generators. Power supply mode When the mains is normal, various EPS power supplies directly supply power to the load through the bypass. Backup and online interactive UPS UPS power supply adjusts and purifies the load through the bypass power supply power, while the online UPS UPS power supply always supplies the inverter and the power grid to communicate power at the same frequency and phase and small load errors. When the utility power is stopped, the EPS power supply and the UPS power supply respectively supply inverter communication power to the load. In order to better maintain information and equipment, when there are abnormalities in the mains, including surges, high voltage pulses, transient overvoltages, voltage drops, line noise, frequency deviations, continuous low voltages, etc., the UPS power supply will automatically be converted to inverters. power supply. Diesel generator type self-provided power plant communication power supply equipment, diesel generator is a device that converts the mechanical energy of a diesel engine into electrical energy. The equipment is operated by a diesel engine to drive the generator. It is a small independent power generation equipment that uses an internal combustion engine as power , AC drives synchronous generators and power generation. To sum up, when choosing UPS power supply, diesel generator and EPS power supply, three kinds of backup power supply, we must distinguish their nature, purpose and reasonable choice. Don't think one-sidedly which is the best, they all have their own uses, and each has its own design philosophy.
