Operational characteristic of the high quality power conditioner with SMES
Abstract
Superconducting magnetic energy storage (SMES) system is getting increasing acceptance in variation applications of power system because of its higher efficiency and faster response. This paper proposes a high quality power conditioner system for the SMES system operation. The power conditioner consists of a voltage source converter using IGBT (Insulated Gate Bipolar Transistor). In order to compensate several problems such as voltage sag and harmonic current flowing in to utility, active filter systems could be a good solution method. SMES is a very good promising source due to the high response time of charge and discharge. This paper presents a simulation technique for a decision method of the specification of the active filter system combined with SMES system. Through the results of several analyses and simulations carried out by PSCAD/EMTDC, this paper demonstrates the significant effect of the control by SMES on the improvement of power system performance. Based on this simulation, authors developed a power conditioner connected to the utility system. It was shown that the developed power conditioner was well-designed and effective. © 2008 IEEE.
