Load Flow Analysis and Abnormality Removal of Bangladesh Power System Using Software CYME PSAF

Load flow analysis is an inseparable part of depth studies on transmission and distribution network of a power system. This paper focuses on setting up CYME PSAF for load flow analysis and its implementation as a real case virtual laboratory. Newton-Raphson method is acknowledged one for fast computational applications. The whole Power System of Bangladesh is chosen for detailed analysis which consists of 404 buses and 223 transmission lines. The analysis and comparison of these simulation results from PSAF reveals that the results approximately depict the precise situation of the real time system as found in the Power Grid Company Bangladesh (PGCB) reports. After the full load simulation in order to reduce line losses and mismatches, different measures such as reactive var compensation, adding parallel line to overloaded lines etc. are done and system is simulated again. The reasonable reduction in line loss as well as mismatches therefore represents better performance.
