Transient Stability Enhancement for Distribution System Using three Phase Unified Power Quality Conditioner with an Intrinsic Power Prediction Technique

R. Rajarajan and Dr.R. Prakash

In recent year the quality and stable power transfer to the transmission line is focused and implemented. The power electronic device is used to enhance the energy stability and reduce the losses in industries and distribution area. In this transmission power is effected in some reasons like sag, swell, overvoltage, under voltage, Total Harmonics distortion (THD) and climatic condition. So this power was not quality in the output side and also harmonics are high so the output was not stable. In this reasons the unified power quality controller is implemented in this work, with help of the proposed Intrinsic Power Prediction Technique (IPPT) to diminishing the THD and provides stable power. The proposed IPPT controller will analyses output of this power system and provides feedback signal to the IPPT controller, this controller give the pulse to converter and with help of the shunt filter and series filter (Hybrid filters) to compensate the power fluctuation presented in the distribution system. In this system the Unified Power Quality Conditioner (UPQC) is connected between the high power generation and distribution system. The power variation should be analyzed in both source and load side, so for an proposed IPPT technique with an Hybrid UPQC filters are used to compensate the all power quality problem in the distribution system. The newly design UPQC with an advanced control approach of an system will be implemented in MATLAB 2017b simulation and the dynamic performance analysis of the UPQC system is obtained under ruining condition. Finally the present model of an UPQC produced the effective result in different parameters of the system especially in THD it will generate the value of 0.64%.
