It is represented using an algebraic equation V = Z I where V is a vector of bus voltage, I is a vector of injected current at each bus where the dynamic components are connected and Z is a matrix representing the impedance of transmission line and other components not modelled separately. The network model consists of all transmission network components except the components modeled separately. The output of the network model is fed back to the dynamic models making it a closed loop system. 1 shows a top level view of the model, where various dynamic models are connected to a network model. Results of an SMIB test system simulation are discussed in Part IV and several suggestions for possible future work are detailed.Ī model of a power system is an integration of several dynamic models such as synchronous generators, asynchronous generators, load, FACTS devices, etc. The Section III explains the procedure for translating the dynamic model into a Simulink model. Following the introductory section, the Section II deals with the modelling aspects of a power system and lists key equations for dynamic model of a synchronous machine. The program can be modified to include multiple synchronous machines, asynchronous machines, FACTS devices, dynamic load etc. A basic methodology for developing a simulation program is discussed without detailing the theory behind the model.

This paper deals with programming of a single machine infinite bus (SMIB) test system using MATLAB/ Simulink software and intended for a complete beginner in the field of power system analysis. They are used to study the operation and stability of the system, controllers design and testing, operator training etc. They are used in the electricity related industry from the early days of digital computers. Modelling and simulation studies are an integral part of power system analysis. Power system dynamics, modelling, Synchronous machines, MATLAB, Simulink The method can be extended to make a program to simulate network having multiple synchronous machines, asynchronous machines, FACTS devices, dynamic load etc. The program is useful to demonstrate various operational and stability challenges in power system operations. The paper illustrates a procedure to develop a dynamic simulation program for a single machine infinite bus (SMIB) test system using MATLAB/Simulink software.
