Abstract

Abstrak Makalah ini menyajikan pemodelan dan kontrol eksitasi melalui automatic voltage regulator (AVR) dan governor melalui automatic generation control (AGC) atau frequency load control (FLC) untuk meningkatkan stabilitas pembangkit listrik tenaga mikro hidro (PLTMH Kata kunci: kontrol eksitasi-governor, pembangkit listrik tenaga micro hidro, PSO Abstract This paper presents the modeling and control of the excitation system via the automatic voltage regulator (AVR) and governor system through the automatic generation control (AGC) or frequency load control (FLC) to improve stability on a micro hydro power plant (MHPP). Three main parts of the generation system are synchronous generator, AVR-excitation, AGC modelled linearly. Generator is modelled by a single machine connected to infinite bus (SMIB) which is equipped by AVR and excitation linear model. Excitation control system made by optimizing the gain of the AVR (KA) and the governor with the gain of the AGC (Ki). Optimization is done using the method improved particle swarm optimization (IPSO). The main purpose of setting the gain of the AVR-AGC is to stabilize the oscillation frequency of the

Power System Design using Firefly Algorithm for Dynamic Stability Enhancement

“…The brigness of a firefly is influenced or determined by the objective function [27]. The objective function used to test the sytem is the Comprehensive Damping Index (CDI) [28,29]. Futhermore the dynamic model of power system will be converted into state matrix in equation (5) and (6).…”

Speed Control and Optimization of Variable Speed Diesel Generator Set

“…The manufacturing and processing of sensors with high reliability, high sensitivity, and excellent electromagnetic anti-interference ability and high-precision, high-response speed actuators has always been the focus of research, and it is also the future development trends of electronic control system component. 2) Research on the mathematical model of the electronic control system [11][12][13][14][15][16][17][18]. The current electronic governor generally adopts negative feedback regulation to control the diesel engine speed, so a more accurate electronic control system and a more suitable diesel engine mathematical model will play a key role in the control system.…”
