INTRODUCTION
Figure 25.1 illustrates the overall protection scheme in a generating station. The auxiliary equipment inside the plant requires 5 to 10 percent of the power generated. The remainder goes to the grid. Since the plant is closely interconnected, a single failure requires more than the electrical and mechanical disconnection of the faulted system. This chapter covers the following topics:
1. The main unit protection. It includes the electrical protection of the plant equipment for which faults result in the tripping of one of the main plant systems.
2. The methods used to initiate the tripping of other associated plant systems.
