In this chapter, an overload and short-circuit protection method is proposed for voltage-source inverter-based uninterruptible power supply (UPS) system. In order to achieve high reliability and availability of the UPS, a short-circuit and overload protection scheme is necessary.
Power distortions such as power interruptions, voltage sags and swells, voltage spikes, and voltage harmonics can cause severe impacts on sensitive loads in the electric systems. Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high-quality power for these sensitive loads.
During a power outage this option becomes unavailable. The UPS must NOT be overloaded during battery operation when the mains is not present. If an overload occurs the UPS will protect itself and sadly drop the critical load because it has no power source for the overload.
The UPS is being overloaded if the load power demand is greater than the rating of the UPS. An overload may happen quickly, or slowly increase above the rating of the UPS. Inside the UPS there are current switching devices which can cope with minor overloads for a considerable time until they become too hot.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
