Design of a custom power park for wind turbine system and analysis of the system performance under power quality disturbances

This study presents an operation of custom power park (CPP) with wind turbine system (WTS). The classical power system stability, changes and challenges in the power system with installation of wind energy sources are given. The CPP is composed by static transfer switch (STS) for WTS. An electromagnetic transient model of a system is composed by WTS and STS in power system computer aided design/electromagnetic transient including DC (PSCAD/EMTDC) programme. The entire model of the proposed system is developed and simulating results are verified in PSCAD/EMTDC programme at different fault types. The system responses of the different fault types are given and obtained results are evaluated in detail for power quality problems. Moreover, of the different type faults are implemented to the WT feeder and the response of the proposed system is observed for all cases. Then, the simulating results are evaluated. The currents and voltages of all systems are investigated during normal, transfer and post-transfer periods and also these simulating results are evaluated.
