Abstract

This paper presents dynamic performance of synchronous generator in steam power plant. Steam power plants are the most popular power plants to date. Until the end of 2018, 48.43% of the total installed capacity of power plants in Indonesia is this type of power plant. The largest steam power plant in Indonesia is in Paiton, Probolinggo, East Java, which is the object of this research. In its operation, the generator in this generator experiences dynamics as electricity load changes. This study discusses the analysis of the performance of synchronous generators to changes in electrical load. The analysis includes the voltage, active power, reactive power, power factor, and generator efficiency variables. The results showed that the generator performance remained good despite serving a very dynamic electricity load.

Highlights

Electrical energy is vital in all activities of human life to meet daily needs
The steam turbine must be protected from all possible causes of disturbances and abnormal conditions that occur, both interference originating from the steam turbine itself or interference or abnormal conditions originating from other parts of the electric power system [12][14]
The type of generator used at PT Paiton Operation and Maintenance Indonesia (POMI)'s unit 7 steam power plant is a synchronous generator

Summary

Introduction

Along with the development of technology that is very rapid, the level of electricity demand every day is increasing in every human and industrial activity [1]-[4]. Power generation to produce electrical energy is increasing and where the nature of electrical energy is channeled and converted into other forms of energy, such as mechanical energy, light energy, heat energy, and others [5][7]. Steam turbines play a significant role in the generation and distribution of electricity in an electric power system. The steam turbine must be protected from all possible causes of disturbances and abnormal conditions that occur, both interference originating from the steam turbine itself or interference or abnormal conditions originating from other parts of the electric power system [12][14]
