Calculation of Booster power requirements and power line flicker for 1.5 GeV proton operation

摘要

The Booster power requirements and power line flicker has been previously calculated for the 1 GEV proton cycle. Since then the maximum proton energy has been increased to 1.5 GEV, and the cycle period increased from 100 to 133 millisec. the design manual lists the peak magnet current as 2220A (previous value of 1672A). The maximum stored energy is increased by a factor of 1.763 and the power swing is increased by a factor of 1.32; increasing the flicker approximately by this factor. The required magnet voltage has been calculated and is given for the dipole and quadrupole strings. The total power at the AC bus bar is given. To calculate the reactive power, the dipole excitation is assumed to consist of 5--1000 volt supplies in series and sequentially switched. The quadrupole supply consist of 5--175 volt supplies in series and sequentially switched. (ERA citation 17:029086)
