Abstract

Improved power quality is the driving capability for today's modern manufacturers. Consumer awareness regarding reliable power supply has risen enormously in the last decade. This has led to an additional impact in the development of small distributed generation (DG). Small isolated DG sets can feed local loads, leading to enhancement in the authenticity of power with low capital investment. These systems also increase importance in remote areas where transmission using overhead conductors or cables is unrealistic or prohibitive due to high cost and other circumstances. Small generation systems in rural areas, islands, hilly terrains, marine plants, aircraft, etc., can be efficiently used in developing countries too. However, these DG sets have to be de-rated if the induction motor loads are instantaneously started. One practical choice is to use DSTATCOM in a shunt structure with the central system to efficiently utilize the full capacity of producing sets. DSTATCOM consists of a voltage source converter (VSC), and it internally has the required capacitive and inductive reactive power. Its control is high-speed and can provide acceptable reactive power compensation to the system to which it is connected. The method of DSTATCOM for solving power quality problems due to voltage fall/dip, flickers, swell, etc., has been suggested. The purpose of DSTATCOM is to provide efficient voltage regulation at the point of standard coupling (PCC) and thus prevent significant voltage dips.
