Superconducting magnetic energy storage for electric power system dynamic stabilization

Conference ·
OSTI ID:6207137

A Superconducting Magnetic Energy Storage (SMES) system is being developed at the Los Alamos Scientific Laboratory (LASL) for a dynamic stabilizer to be installed in the Bonneville Power Administration (BPA) power system at Tacoma, Washington, by 1982. This unit will be an alternate stabilization method to the dc modulator now used to stabilize the 900 mile, ac intertie between BPA and Southern California. The generation control systems' response to the constantly occuring, small-load and voltage changes can result in negatively damped, low-frequency power oscillations. The dc modulator provides stabilization by fast load control of the High-Voltage dc (HVDC). The SMES unit consists of a 30-MJ solenoid, a 10 MW convertor, a liquid helium dewar and auxiliary systems which operate independent of the HVDC system. The SMES dynamic stabilizer design is presented with status information about the superconducting coil, the converter and other components of the SMES dynamic stabilizer summarized.
