Abstract

The order model of synchronous generator plays very important roles of determine the accuracy of power system dynamic study. This paper presents the simulation and analysis of the sixth order model of synchronous generator for power system dynamic study by using Simulink. The mathematical model of stream turbine governor and exciter are also considered in this paper. The presented method is tested on the single machine infinite bus system.

Highlights

  • The dynamic behavior of power systems is important to both the system organizations, from an economic viewpoint, and reliability viewpoint

  • The stream turbine consists of mechanical-hydraulic governors for stream turbines and the exciter system can maintain the system returning to the steady state almost at the same time

  • It can be mentioned here that governors and exciter system can improve the dynamic behaviors of power system

Summary

INTRODUCTION

The dynamic behavior of power systems is important to both the system organizations, from an economic viewpoint, and reliability viewpoint. The first is referred to as the momentary mode In this approach, all power system components including synchronous generator, exciter, and stream turbine are modeled in the detailed of three-phase sine functions. Most commercial software packages such as DigSilent, PSCAD, and EMTP are used this approach [2]-[3] They are suitable for power engineering industry. The second approach is called stability mode In this approach, all power system components are model in the much simpler way by using one phase rms function [4]. All power system components are model in the much simpler way by using one phase rms function [4] This approach is very suitable for integrating in curricula. Reference [6], [7] used
