Description
Summary:Real time simulation is becoming an essential simulation environment for engineering design, especially in power systems. This paper discusses two real time simulators applied to power system simulation: real time digital simulator (RTDS) and National Instruments-PXI (PCI eXtensions for Instrumentation). RTDS is an efficient tool for the design, development, and testing of power system and its components. NI-PXI is a high-performance and low-cost PC-based platform, used for simulating wide variety of systems. Virtual testing of power systems on the NI-PXI and its potential power system simulating capabilities has been discussed here. The performances of both the simulators are studied and compared by running an eight-bus power system under different fault conditions in real time. A Schweitzer Engineering Laboratories (SEL)-351S directional over-current relay is used to test these power system simulators. The SEL reports obtained by simulating the power system on these simulators are compared as a part of verification process.
