Abstract: The power consumption in industrial settings should be minimized not to incur heavy penalties for excessive use. One of the ways to do this is using an Automatic Power Factor Correction (APFC) unit containing a fuzzy control system. Low power factor and increased power consumption are problems for industrial companies, as utility providers often levy penalties on them. Such penalties are generally assessed to reward consumers into developing a stable and economical pattern of electricity consumption. An APFC unit can be implanted to effectively raise the power factor and thereby reduce total power consumption. It is an electronic device which automatically can adjust the reactive power within an electrical system to a predetermined level of power factor. It also monitors the real-time power factor and make necessary modifications to maintain a system at its optimum operating level. Fuzzy control is a design method for systems based on principles of fuzzy logic. Working with imprecise or uncertain input data and shaking off numbness in a dynamic environment are possible.
The APFC unit can meter out reactive power through fuzzy control techniques in response to changing loads, voltage variations and all the other general operating conditions. The addition of fuzzy control to the APFC unit allows that device to adaptively compensate for real-time conditions. This leads to more effective management of power factor and helps avoid penalties for poor power usage profiles. A combination of an APFC unit and fuzzy control has great advantages for reducing penalties on industrial power consumption. The APFC unit keeps the power factor within acceptable limits, thus reducing penalties paid on account of poor power factor. With the use of fuzzy control, the APFC can compensate for reactive power in response to real-time conditions and energy is used more efficiently this way. With the usage of SD card module, the data can be effectively stored and can further use the data for future technological advancements.
