Abstract

In the paper, the standard IEEE 10-generator 39-bus test system is simulated offline and also in real-time using an educational real-time simulator, called miniature full spectrum simulator (Mini-FSS). In a power system, the interactions between one another among the various generators, their excitation systems, and their automatic voltage regulators lead to low-frequency oscillations. Power system stabilizers (PSS) are used to damp out such oscillations. This paper reviews the design of PSS and implements the same on the test system considered. For the design of the stabilizer, a small signal model of the system is derived by modeling the machines using the 1.1 model and linearizing them about the operating point. With the stabilizer implementation, damping of the oscillations in terminal voltage, excitation voltage, and rotor angle difference is clearly observed. These are contrasted with those results without the stabilizer implementation. Dynamic response of the system to 10 percent step-change in terminal voltage reference is also studied. Computation time taken by the real-time simulator is also ascertained. The educational real-time simulator, which consists of 9 DSP processors for parallel computation, is found capable of simulating the 10-generator system in real-time with only one processor, completing the calculations in each computational step within 30 μs.
