Electrodynamics power system simulator for bulk power systems investigations and for testing, debugging and adjustment of various digital control and automation systems

Now on power stations and in electric power systems of UPS of Russia there is a process of modernizing and replacement morally and physically out-of-date inventory, including devices of automatic control, regulation, protection and automation, basing on semiconductor elements. They are replaced by various microprocessor digital devices. JSC "HVDC Power Transmission Research Institute" (NIIPT) performs testing, debugging and a preliminary adjustment of the generators\´ automatic excitation regulators and power system stabilizers in conditions, corresponded to operational conditions in power system. Tests are performed using specialized electrodynamics power system simulator (EDS). Tests on the EDS ensure essential reduction of starting-up and adjustment works volume, their cost and, correspondingly, terms of power installations commissioning.
