A Reconfigurable Uninterruptible Power Supply System for Multiple Power Quality Applications
A Reconfigurable Uninterruptible Power Supply System for Multiple Power Quality Applications

... To illustrate the development of the proposed UPS system, let us begin with a simple single-phase half-bridge inverter, the circuit topology of which is shown in Fig. 5. It can be seen that this topology operates by causing the load current to flow directly through the dc capacitors. As the switches ...

Islanding

Islanding refers to the condition in which a distributed generator (DG) continues to power a location even though electrical grid power from the electric utility is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices. For that reason, distributed generators must detect islanding and immediately stop producing power; this is referred to as anti-islanding.The common example of islanding is a grid supply line that has solar panels attached to it. In the case of a blackout, the solar panels will continue to deliver power as long as irradiance is sufficient. In this case, the supply line becomes an ""island"" with power surrounded by a ""sea"" of unpowered lines. For this reason, solar inverters that are designed to supply power to the grid are generally required to have some sort of automatic anti-islanding circuitry in them.In intentional islanding, the generator disconnects from the grid, and forces the distributed generator to power the local circuit. This is often used as a power backup system for buildings that normally sell their excess power to the grid.
