Modern power systems, employing an increasing number of converter-based renewable energy sources (RES) and decreasing the usage of conventional power plants, are leading to lower levels of short-circuit power and rotational inertia. A solution to this is the employment of synchronous condensers in the grid, in order to provide …
Understanding Fault Technical Report
A fault in an electrical power system is the unintentional conducting path (short circuit) or blockage of current (open circuit). The short-circuit fault is typically the most common and is usually implied when most people use the term fault (Grigsby 2001). We have limited our discussion to the short-circuit fault variety for this technical ...
