Abstract
Abstract Power systems rely more and more on a wide range of equipment that regulate power plants, voltage and reactive power, or protect the grid against malfunctions. To test these various equipment, such as relays, controls or power electronic devices, analog simulators have been developed over the years. However, the poor flexibility and the maintenance costs of these simulators opened up the way for fully digital real-time simulators able to simulate high frequency phenomena: the real-time Digital Transient Network Analysers (DTNA). Up to now, DTNA's used mainly hybrid or non-standard technologies that limited their assets compared to analog simulators. This paper presents a new and fully digital real-time DTNA that can perform real-time tests on a standard multi-purpose parallel computer: ARENE. This new facility will be used to test all kinds of equipment from protective relays to generator controllers, HVDC or FACTS prototypes or controllers.
