The first uses the Teaching Learning Based Optimization (TLBO) to solve the optimal capacitor placement problem in electric distribution systems. The second uses ETAP software and its integrated tool of optimally placing power factor correction capacitors.
This means that the capacitor placement problem transforms to an optimization problem and should be formulated with some desired objective function (such as loss minimization) and various technical constraints (e.g. the limits of voltage levels and power flow) .
04.07 Maintain personal protection equipment. 04.08 Report unsafe conditions/practices. Basic Electricity, DC/AC concepts. This lab is designed to help students understand the concept of capacitance and how materials, surface area, and thickness impact the performance of a capacitor. After this activity, students
Conventionally, there are two strategies to deal with the problem of capacitor placement for reactive power compensation. Either a bank of capacitors is placed at each power system bus or simply placing a bank of capacitors at the mains to enhance the overall system power factor.
The main constraints for capacitor placement are: To ensure that all voltage magnitudes of load (PQ) buses should be within the limits andto ensure that power factor (PF) should be greater than a threshold. It may be a maximum power factor limit.
Either a bank of capacitors is placed at each power system bus or simply placing a bank of capacitors at the mains to enhance the overall system power factor. The effectiveness of either strategy depends on the criticality of the system.
