详细说明： Chapter 1 introduces the basic components of a distribution system. Included is an introduction to the type of data that is necessary to model a distribution system. Chapter 2 is a discussion of “load.” The attempt here is to make the student understand that the load on a distribution system is constantly changing, and that this must be taken into account in all studies. Chapter 3 presents some helpful approximate analysis techniques that will help the student know what “ballpark” answers to look for when more precise studies ar e made. Chapter 4 is a very important chapter in developing the exact model of line segments. How to take into account the unbalanced loading and unsymmetrical configurations in the calculation of line impedances is presented in great detail. Both overhead and underground lines are included. Chapter 5 is in many ways a continuation of Chapter 4, except that it is limited to shunt admittance calculations. Chapter 6 develops the first of the generalized matrices that will be used to model the major components of a distribution system. This chapter is limited to the three-phase, unbalanced line model. Chapter 7 addresses voltage regulation. Starting with a review of basic transformer theory, the chapter moves to the development of three-phase models of step-voltage regulators and their control. The models developed are in the form of generalized matrices similar to those developed for line segments. Chapter 8 develops comprehensive models of several of the standard three-phase transformer connections that are common on a distribution system. The models, again, are in the form of generalized matrices. Chapter 9 develops the models for the various types of loads on a distribution system. Chapter 10 puts it all together. All of the component models developed in earlier chapters are put together to form a model of a distribution feeder. The ladder iterative technique is developed and demonstrated. Also, the three-phase model for short-circuit studies is developed and demonstrated. ...展开收缩
