| Abstract |
This paper presents a new application example of flexible ac transmission systems (FACTS) devices in the advanced industrial power control schemes. An integrated multi-functional power quality controller and energy saving system based on the unified power flow controller (UPFC) is proposed. The proposed integrated system can compensate the reactive power, harmonic current and the unbalanced power of the controlled distribution system with a capacity-limitation manner by its shunt branch. It also can regulate multiple load voltages simultaneously based on the prescribed P-V characteristics of distinct loads for the purpose of energy saving via its series branch. The detailed design procedure of the controllers providing flexible hardware configuration and multiple control functions is presented. A 15KVA test-system with the variable structure UPFC configuration performing active power filter functions and simultaneously regulating an 7HP induction motor for energy saving is numerically investigated with EMTP programs. The feasibility and effectiveness of the proposed system and the related control techniques are confirmed through some simulation results. |
