Abstract
It is obvious that power flow study and analysis are important to any kind of electrical power system engineering. The main purpose of this research paper is to study and analyze the power flow and system stability of the 24.6 MW Diesel Power Plant (DPP) which is the cement manufacture located in Cambodia at 6.9 kV bus using the commercial electrical transient analysis program called ETAP. Such a power plant comprises of four diesel generators with the generation capacity of 6,150 kW each. There are three outgoing feeders to different load type in various processes in this manufacture. Power flow study and analysis in this paper includes steady-state conditions to assure the voltage drop, voltage regulation, active and reactive power flow limits, transformer capabilities, cable sizing, and power factor at all connection points. Four cases of operations are in consideration in this research. All diesel engine generators assume to be operating in isochronous load sharing control. Nominal system voltage is at 6.6 kV plus/minus 5%. Maximum continuous operating voltage of the interest island system is 105% of 6.6 kV and minimum continuous operating voltage is 95% of 6.6 kV nominal system voltages. All motors loads are IEC standard design, typical motor load data from ETAP software database is used for this study. The simulation results will be shown here in this paper. The simulation results analysis, discussion and conclusion are also illustrated.
