Study of SMES System with DC Intertie for Power Line Stabilization
A new superconducting magnet energy storage (SMES) system proposed by one of authors for power transmission line stabilization is studied by an experimental model system and computer simulation. It has a SMES in a dc intertie section connected to ac transmission lines via convertors. The distinctive characteristics of this system is that independent stabilization can be made for each ac line and also that the power flow through the dc section can be controlled. For verifying these characteristics we developed a model system consisted of a superconducting pulse magnet (lOOkJ), pulse width modulation (PWM) convertors, simulated power line system with a generator (lOkVA) and a short-circuiting device to give power line fault.
