Modeling and analysis of custom power park by PSCAD/EMTDC program

The advances in power electronics based devices to improve power quality have been increased the interest on Custom Power Park (CPP). CPP concept means the integration of multiple CP Devices within the Industrial/Commercial Park, which offers customers high quality of power at the distribution system voltage level. CPP is one of the most useful solutions to prevent voltage sags/swells and harmonics from distribution lines.In this thesis, CPP has been modeled by using PSCAD/EMTDC program. CPP is composed of Static Transfer Switch (STS) and Dynamic Voltage Restorer (DVR). The operation principles of STS and DVR have been explained in detail and then they have been modeled with PSCAD/EMTDC program. Simulation results have been comprehensively investigated. Different types of faults are applied for STS and DVR in CPP and the response of the system for these disturbances are examined.
