A Multi-machine Power System Installed with Power System Stabilizers

Figure 5.1 shows the configuration of a two-machine power system where two synchronous generators are connected by a transmission line. This simple system is used in this section to demonstrate the procedure of establishing the mathematical model of a multi-machine power system . Later, it will be used for introducing basic concepts and methods in the analysis of power system oscillations and design of PSSs in the multi-machine power system. For the purpose of demonstration, a load is connected at the terminal of two generators and a node along the transmission line, respectively.
