摘要

Considering the last two to three decades, the industrial load / application demands have widely grown in terms of speed, accuracy, controllability, dynamic response and features. Added to these are restrictions / penalties by the utility side in respect of the voltage and current distortion, maximum or peak reactive power, maximum KVA and excess KW drawn by the consumer. This has exerted considerable stress on the designer and the manufacturer of power electronic equipment's who have to satisfy both the consumer as well as the utility and provide the answers through the available power electronic devices and the controllers. As a part of this major battle and also as a part of the power quality drive, reactive power compensation technology has also undergone tremendous amount of change starting from the switched capacitors (electromechanical and thyristorised) to active converter based compensation. This paper addresses the need for such active converter based technology, the demand verses economical solutions offered through it, practical results of such a technology working with Windmills and spot welding applications, and insight in the design while meeting the load / application challenges in terms of load dynamics. It further throws light on possible ways of meeting dynamic load requirements upto 4 MVAR while maintaining the input power factor close to unity. The technological solutions are based on use of self commutated IGBT (Insulated Gate Bipolar Transistor) power devices controlled through existing Intel processor with embedded software developed to tune the load dynamics.
