Circuit breaker (CB) installed for capacitor bank is the CB which commonly experiences the switching process due to the capacitor bank function as a voltage regulator. In closing switching process, CB encounter transient condition due to inrush current. In this paper, the simulation for studying the inrush current characteristic of capacitor bank switching in Indonesia has been performed. Simulation...
In Indonesia distribution system, the power distribution from 20/0.4kV transformer to customer feeder is done using low voltage switchboards. Low voltage switchboard utilized in Indonesia distribution system is consist of several fuse rails, where each fuse rail supplies one customer feeder and the amount of fuse rail that is mounted to low voltage switchboard is depended on the capacity of 20/0.4kV...
The isolated electrical system is the one solution for electrical distribution in the archipelago. Any disruption to this system would disserve the public and detriment the utility companies because it can't sell the energy. The problem of an isolated solar plant failure is happened in Indonesia exactly in System A. Currently, there are few references that address the investigation of real cases problem,...
This paper discuss about the investigation of 150kV capacitor voltage transformer (CVT) breakdown which is occurred simultaneously after capacitor bank disconnecting process. Analysis is performed referring to the last routine maintenance and digital fault recorder (DFR) data. Based on the analysis of both data and transient simulation analysis from the model created to represent the condition during...
In Indonesia, there are many capacitor bank installed to regulate the nominal voltage. Currently, the Recovery Voltage (RV) data related to the capacitor bank switching is unavailable, whereas this data is very important to analyze Circuit Breaker (CB) performance to understand whether it will success to interrupt the current or not. In addition, if the CB cannot retain the RV, it will degrade the...
This paper discuss about effect of traction substation for high speed railway in Indonesia. The purpose of this paper is to obtain magnitude of voltage and current unbalance due to traction substation that perceived by system and generator adjacent to traction substation. Analysis is performed by doing simulation of 5 scenarios in simple system model that created in power system simulation program...
Calculation of transmission line parameter such as capacitance and inductance had been done by several researchers. However, it's common that in calculation, the earth surface under the transmission line is assumed to be horizontal. In fact, the earth surface is not horizontal but has an uneven contour. This paper explained a method to determine the parameter value of transmission line which passing...
This study is performed to determine the phase arrangement for 500kV quadruple circuit transmission line that will be used in Indonesia. The phase arrangement selection is based on the value of electric field and magnetic field exposure. The purpose of this method is to obtain phase arrangement with minimum value of exposure to electromagnetic fields. Simulation is conducted using numerical analysis...
Four circuits transmission line is an alternative solution to transfer high quantity of electrical power. The transmission line has four parallel circuits on a tower and can be categorized as a new type of transmission line in Indonesia. Therefore, its electrical characteristics should be investigated. This paper studied the switching transient of the transmission line and evaluates the electrical...
This study determines the influence of lightning stroke current on 500 kV quadruple circuit transmission lines that will be used in Indonesia's power system. Analysis is conducted in ATPDraw and multistory model is used in modeling of transmission tower. Lightning induced voltage across insulator strings is the main factor being considered in this paper. Therefore, effect of varying lightning current...
