| Abstract |
A system, consisting of a magnetically suspended high speed turbine-generator machine set and an
AC/AC converter is applied in gas expansion stations for pressure reduction. This system, apart from
producing active electric power, can also be operated to provide power factor correction and, as the
primary energy source is independent from the mains, UPS service. In this paper the operation
parallell to the line and operation as UPS is investigated by numerical simulation. The simulation was
veryfied by measurements from an installation to be commissioned in summer 2001. |
