Abstract:

This paper demonstrates with Active Power Filter and Passive Power Filter. It is great specified in Minimizing the voltage and current based harmonics and improvement in the Power factor with the relatively low capacity active power filter. In reconstitute power system, Power Quality is one of the most important Modern eras. The Problems associated with the voltage sags and voltage swells are one of the powerful impacts on the sensitive loads. To recover from this problem, Custom Power devices are usually used. One of those devices is Dynamic Voltage Regulator (DVR) and Fuzzy Logic Controller (FLC). The Dynamic Voltage Restorer (DVR), which is one of the most effective in modern custom power devices used in Power Distribution Network and Fuzzy Logic Controller (FLC) control the algorithm DVR is proposed in this paper to control the load terminal voltage during the sag, swell in the voltage at the point of common coupling (PCC). An adaptive fuzzy dividing frequency control method composed of a generalized PI control unit and fuzzy adjustor unit was proposed. In the new control scheme, The PI control unit is used to achieve dividing frequency control method whereas the fuzzy adjustor unit is used to adjust the parameters of the PI control unit to generate better adaptive ability and dynamic response. The Fuzzification rules are used to generate The Dynamic Voltage Regulator (DVR). This voltage is injected in series for the pulse Width Modulation (PWM) Control and problems associated with Power Quality are not only easy to be calculated and implemented, but also very effective in reducing harmonics.
