What is each offer?

low voltage ride is the ability to respond to the main reduction in energy input for alternative energy sources such as wind and solar power plants. It is predefined so that the load can be disconnected or under voltage of alternative sources such as uninterruptible power sources (UPS). Many critical applications such as satellites and spacecraft are also considered to ride voltage through the design through the design. Most electronic devices can be able to function between about 60 and 130 V AC current (VAC). The drained electricity is approximately the same, although the voltage has dropped due to flexible power circuits. The power supply power supply is able to change the time "ON" on its main switching device to create the same average direct current (DC) voltage for its load. Electronic circuits implement low voltage driving to some extent, as well as the size of the capacitor components. Practical design can provide low -voltage rideUp to about half a second.

Failure driving is a more general feature that includes low -voltage rides and other failures such as exaggerated wind turbines. It is the ability of a power supply to maintain its output voltage due to a short -term power drop. The wind generator farm can undergo reduced wind speed, leading to a drop in voltage. Meanwhile, the power supply may require the same amount of energy that can be provided for a moment by the backup mechanism on the generation device.

Reactive devices are able to support a low voltage ride for short -term energy loss. The capacitor or capacitor is able to provide electricity taken from the electric field generated between the conductive plates, while the inductor is able to produce the current when the winding taken from the magnetic field collapse in its Core. The magnetic core is capable ofSave a strong magnetic field.

Another source for low -voltage ride is inertial storage. In this form, the mechanical energy can be stored as the momentum of a rotating flywheel. For example, using magnetic bearings can be a heavy flywheel weighing at least 220.5 lb. (100 kg) suspended in the vacuum and once suspended, the flywheel has an engine drive that uses additional electricity to create the speed of rotation. Without any resistance, the flywheel is still rotating. During the power outages, the generator occupies a flywheel and converts rotary energy into electricity.

The

battery is able to ensure a low voltage ride for up to several hours. There are systems that use DC directly, so there is no need to convert electricity during power failure. In some In-Line UPS systems, it generates AC current (AC) in the synchronization with a network force. If for some reason the power supply is not available, the UPS controls the load of the force. When the network forceReturn, UPS electronics will come up and return to tracking.
