Stability Improvement by Reducing Voltage Fluctuation using SVC in Penetration Wind Power System

Abstract

Currently, wind energy is a renewable energy that is growing because some of its advantages are connected to the grid system. This study is focus on presenting a probabilistic theory to design power system stability (PSS) and excitation of the FACTS system controller generator via Static Var Compensator (SVC) connected to wind turbines in Sidrap, region of South Sulawesi system. The purpose of the test system is on oscillation, profile voltage and influence stability of wind turbine penetration. An oscillating system requires system performance compensation from the side of the machine via PSS and transmission via SCV to increase the depth of the electro mechanical mode. So, the simulation results on 44 buses in the South Sulawesi system show the stability of the system and rapid voltage improvement and can reduce the oscillation that occurs. This system is tested using a time domain-based PSAT software simulation on the system.

Parallel Induction Analysis for Reduction of Interference Due to Lighting Strikes At 70 kV SUTT Parakan-Kadipaten

“…In the course of the lightning impulse current to the tower grounding system, the current will pass through the tower which has a tower inductance L. The presence of L will produce a high voltage due to each lightning strike IOP Publishing doi:10.1088/1755-1315/1157/1/012038 2 having a steep current wave [3]. The back flashover phenomenon will occur when the voltage on the line insulator is greater than or equal to the critical voltage of the insulator fire jump so that a fire jump occurs in the insulator [4][5][6][7][8][9][10].…”
