At present, many people using power saving equipment (UPS) still think that the power storage device only functions to save power temporarily when the power is lost. Electrical storage device has not been properly evaluated with the value it brings to business activities and daily life of people.
So the question is “What is the value of a storage device?”. (This article focuses on the value of a power storage device to a business. And of course some of these values are also true for the personal user for everyday life.)
- The first value, you can see right from the name of this device is translated into Vietnamese – “power saving device” – that is the function to save electricity when the power is out. Obviously, for a device or equipment system to operate continuously, continuous power supply is indispensable. With an economy that is considered “growing”, forecasts of electricity demand have increased greatly over the years, coupled with a slowdown in research and innovation in electricity generation technology. so maintaining a stable power source is a huge challenge for Vietnam. Vietnamese enterprises are forced to accept and overcome this limitation by themselves in order to develop their business. Many businesses aim to use generators, but in addition to the inherent advantages, generators still have disadvantages such as noise, poor output quality … Therefore, with the function of saving electricity, UPS also is a solution that many businesses have been, are and will use.
- Second value, we analyze the English name of the UPS device is “Uninterruptible Power Supply” or “Uninterruptible Power System” or “Uninterruptible Power Source”. In English sense, UPS can be understood as uninterrupted power supply or uninterruptible power supply. What is uninterruptible power, and what conditions ensure that the power supply to the device is continuous? Uninterruptible power supply (as analyzed above) and potential risks. So the convenience will depend on the backup power source is the UPS, and the condition to ensure that the power supply to the consuming equipment will be accumulated on the UPS (of course, the mains power is still indispensable in case). The UPS itself must meet the requirements for the quality power of power consuming equipment. To understand this we will look at the power requirement of a device that consumes power (load) and why it is difficult (or impossible) to meet the power requirements of the loads properly. / li>
- About load input power requirement – sufficient capacity, voltage, stable frequency (permissible fluctuation), small harmonic distortion …
- About the quality of the mains power- a quality mains power will not have the following problems:
- Power failure: the cause is a fault from the power plant, the line power transmission, intermediate protective devices (voltage cooler, fuse, circuit breaker) … lead to power failure
- Temporary drop in voltage (Power sag): the cause of the device is dissipated high power consumption starting, switching operating modes … causing voltage to drop temporarily in some time.
- Power surge: caused by lightning, switching … appear electrical pulses propagating on the source line.
- Under-voltage: due to phase loss, the amount of load used increases rapidly … causing voltage drop, low voltage. li>
Nine power quality problems
- Over-voltage: large change in load capacity, system failure … causes overvoltage.
- Line noise: occurs due to loads nonlinearity in the electrical system, motor loads, transceiver equipment … causing propagation disturbances in the source path.
- Frequency variation: due to mains or generators Poor quality power causes the frequency to vary greatly from the standard frequency (50Hz / 60Hz)
- Switching transient: caused by switching (on / off) the load power consumption, electrostatic discharge causes high voltage pulses to appear, rapidly spreading on the source line.
- Harmonic distortion: (Harmonic distortion): caused by nonlinear loads, inverter … cause power source distortion.
All of the above problems of the mains power can occur individually or at the same time cause failures, reducing the service life of the power consumption loads, data loss …
Each power supply problem can be eliminated when using individual protective equipment such as surge suppressor, harmonic distortion filter, voltage stabilizer … However, if combined Electrical equipment on a power system will cause costly investment, and may increase the failure, single point of failure …
UPS with inherent features (operating principle) and some additional features will help you with power supply problems (depending on the type of UPS used) when connecting the drain load. receptor at its output source. At this point, you can know the value of the device is more than just saving electricity.
