Power Flow study is the starting point in the planning stage for a new power system or a future expansion to an existing system.
We study all operating scenarios and identify overloaded equipment and cables. We determine the active and reactive power, voltage, current, and power factor throughout the power system.
We also exam the performance of the system during maintenance situations. For example, if a transmission line or a transformer is taken off line due to planned maintenance or due to a fault, can the remaining lines or transformers perform safely and can it support the loads without interruption or the need for load sheading.
We note the rating of all electrical equipment such as transformers, cables, switchgears, motor control centers, and distribution panel boards. We identify the percentage of rated load during normal and worst case contingency operation.
We determine the percentage of rated voltage of all buses during normal and contingency operation and while direct online starting of large motors.
We end the report with conclusions and make recommendations.
