Ann Controller Based Adaptive Shunt Hybrid Filter for Static and Dynamic Loads

Chapter 3 presents ANN based adaptive shunt passive filter, whose performance is found to be superior to fixed element shunt passive filter in harmonic and reactive compensation. However, the drawback is that it can provide only partial harmonic and reactive power compensation. Hence, an ANN based digital controller for active filter is developed. It compensates for the major portion of source current harmonics and reactive power under varying load condition as stated in Chapter 5. But this harmonic mitigation scheme requires active filter, whose rating is almost near to that of the load. Therefore, an effective filter configuration with reduced active filter rating is required.
