D-STATCOM for Power Quality Improvement Trained by ANN

Power quality has become an important issue since many loads at distribution ends have become intolerant to various power quality issues. The power quality issues such as voltage sag, voltage swell and harmonics which are certainly major concerning issues in the present era. These issues can lead to failure of the many sensitive loads connected to the distribution system. To solve this problem advanced custom power devices are used. One of such device is the Distribution Static Synchronous Compensation (D-STATCOM). DSTATCOM provides to maintain the desired power factor, voltage and also suppress the harmonic content in distribution network. The event of power quality is detected by trained artificial neural network then the appropriate event will be mitigated using neural network aided D-STATCOM. The results show clearly the performance of the Artificial Neural Network based D-STATCOM in mitigating the voltage sag, harmonics, reactive power compensation and power factor improvement.
