Voltage quality enhancement with custom power park

In the recent years, power electronics based Custom Power (CP) devices that solve these problems attract attention. However, the system formed by putting together the CP devices in an industrial/commercial power park is known as Custom Power Park (CPP). The CPP provides continuous and high quality power to the customers having sensitive loads.In this thesis, a CPP is designed, simulated and made experimental analysis to enhance the voltage quality. The CP devices which are modeled, made experimental analysis and put together in a prototype low voltage power park are Dynamic Voltage Restorer (DVR) and Static Transfer Switch (STS). A new voltage compensation method is proposed for the DVR. However, a new sag detection method is presented for the DVR. The same detection method is also proposed for the STS. The proposed control methods are used for both devices in simulations and experimental setup and get successful results. Finally, the STS and the DVR are integrated to a power park prototype and the CPP is set up. The voltage quality improvements with the help of this CPP are examined against various fault scenarios.The publications made as a result of these studies will contribute to scientific literature. Besides, it will also contribute to become conscious about a new country wide progress ?finding solutions to the electric power quality problems? and this will also contribute to the using of power quality devices in our country.
