WitrynaThe great importance of power flow or load-flow studies is in the planning the future expansion of power systems as well as in determining the best operation of existing systems. Also the system can be analysed and simulation results can be studied before any new change in the existing system without affecting the original system. WitrynaA successful load flow study can calculate the voltage at each bus, the voltage drop on each feeder, and the power flow and losses in all branch and feeder circuits. The most common uses for load flow studies include: Optimisation of components. Identifying reactive and real power flows. Reduce kW and kVar losses.
