A Simple Control Algorithm for Three-Phase Shunt Active Power Filter for Reactive Power and Current Harmonic Compensation

Power quality issues are becoming a major concern of today's power system engineers. Shunt active power filter (SAPF) is one of the effective means for harmonic current compensation in electrical power system. The performance and dynamic characteristics of a three-phase SAPF with a simple control algorithm is presented and analyzed in this paper. This algorithm operates at fixed switching frequ...

On the AC-Side Interface Filter in Three-Phase Shunt Active Power Filter Systems

The proper selection of the AC-side passive filter interconnecting the voltage source converter to the power supply is essential to obtain satisfactory performances of an active power filter system. The use of the LCL-type filter has the advantage of eliminating the high frequency switching harmonics in the current injected into the power supply. This paper is mainly focused on analyzing the in...

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

Single-Phase Shunt Active Power Filter Using Indirect Control Method

A single-phase shunt active power filter is used mainly for the elimination of harmonics in single-phase AC networks. In this paper a single-phase shunt active power filter based on, an indirect control technique is designed and simulated. This control technique is achieved by phase shifting the input signal(voltage/current) by π/2.The overall action of the shunt active power filter to eliminat...
