Abstract

Short circuit is one type of interference that often occurs in electric power systems. The interference if it lasts a long time will affect the quality and continity of electrical power distribution as well as the reliability and safety of the equipment on the system. To minimize the possibility of interference and to minimize the consequences caused by interference, an analysis of disturbances in the electric power system is needed. This study discusses the classification and analysis of disturbances in the electric power system. The type of interference in the electric power system is classified into two, namely symmetry and non-symmetrical interference. Symmetry disturbances are three phase disturbances which are described by the equation of the sequence of the symmetry component system. Sequence equations from the symmetry component system are positive sequence equations, negative sequence equations, and zero sequence equations. Non-symmetrical interference is a disorder that often occurs in electric power systems, namely the interference of one network to the ground, network interference to the network and interference of two networks to the ground. This research is to classify and to analyze the types of disturbances in the Java-Bali electric power system 500 kV 20 buses in the form of a single line diagram, using Power World Simulator and ETAP Software applications. The simulation results are calculated and display the simulation design of the power system with the tools contained in the program.

Abstract

Buck Boost converter controls the use of efficient and economical low and medium power applications, another advantage is its simple design. Very fast response speed, low harmonic distortion components, and high power factor. In this paper, simulation control of the Buck-Boost DC Motor is presented using PSIM software. The results of the analysis and simulation with the PSIM program can be summarized as follows: In open loop dc motor speed, stable in 4.181 seconds and DC motor speed -2.499 rpm. In a closed loop controlled condition, the dc motor speed is stable at 2,308 seconds and the DC motor speed is 6,702 rpm.

Abstract

Fuzzy Logic Control (FLC) is a reliable control system for controlling nonlinear systems, but to obtain optimal fuzzy logic control results, optimal Membership Function parameters are needed. Therefore in this paper Particle Swarm Optimization (PSO) is used as a fast and accurate optimization method to determine Membership Function parameters. The optimal control system simulation is carried out on the automatic steering system of the vehicle model and the results obtained are the vehicle's lateral motion error can be minimized so that the movement of the vehicle can always be maintained on the expected trajectory

Abstract

In this paper, we present the doubly-fed induction generator (DFIG) model in a wind turbine system as a unit of the distributed generator. The wind turbine driven by doubly-fed induction machine is a part of the distributed generation which feeds ac power to the distribution network. The system is modeled and simulated in the Matlab Simulink environment in such a way that it can be suited for modeling of all types of induction generator configurations. The model makes use of rotor reference frame using a dynamic vector approach for machine model. The fuzzy logic controller is applied to the rotor side converter for active power control and voltage regulation of wind turbine. Wind turbine and its control unit are described in details. All power system components and the fuzzy controller are simulated in Matlab Simulink software. For studying the performance of the controller, different abnormal conditions are applied even the worst case. Simulation results prove the excellent performance of the fuzzy controller unit as improving power quality and stability of the wind turbine.
